Ingenuity and thriftiness allow you to improve country cottage area at low cost. One example of using your skills and abilities is the construction of a greenhouse or greenhouse from unnecessary old window frames. Such a greenhouse will be no worse than a greenhouse structure built from new materials, but construction costs will be significantly less.

Selection and preparation of a site for a greenhouse

Important! The foundation will be finally ready after hardening. Which takes 2-3 weeks.

The main elements for the construction of greenhouse walls are window frames. They must be connected to each other into a single, durable structure.

To do this, from boards 4-5 cm thick, a frame, installing the vertical posts first in the corners of the greenhouse, and then connecting them at the bottom and top.

The frames are attached to these racks, connecting each other with their long sides. Self-tapping screws are used as fasteners, as well as metal corners.

For greater stability of the structure, it is additionally reinforced with support bars, nailing them to the inside of the frame.

Cracks and holes that appear in the structure are sealed polyurethane foam or sealant.

The best for a greenhouse is single-slope or gable roof type, which provides the necessary slope for water drainage during precipitation.

The choice of roof type is largely determined by the availability of a sufficient number of prepared parts. If they are lacking, preference is usually given to a pitched roof.

A greenhouse made from window frames has a significant weight. Therefore, in order to avoid making it even heavier, it is better not to erect heavy roof structures over it. It's enough to make it easy sheathing of the upper part greenhouses and cover the “ceiling” with polycarbonate or film, securing it with special clamps and clamps.

For lathing, slats, mounting profile or steel wire are used. If you plan to use the greenhouse in the future, it is recommended to do this in advance. extra seats for attaching threads that can be used to tie up seedlings.

It will become even easier to build a greenhouse from frames by watching the corresponding videos and photos with the stages installation work:

Ready-made greenhouses from cellular polycarbonate and ideal aluminum profiles They certainly look great. But their price is so high that even the most economical gardener may completely lose the desire to acquire such a miracle. And everyone who does their best builds their own greenhouses and greenhouses literally from scrap materials - it’s not beautiful, but it’s practically free and very practical. And in this regard, those who often visit the city are especially lucky: today the fashion for plastic windows It’s simply at its peak, and orderly rows of old and quite decent wooden frames, even with intact glass, appear every day near landfills. It’s enough to just go with a trailer to such places twice – and that’s it: building a greenhouse from window frames is not difficult. All that remains is to understand the intricacies of making a small foundation and erecting a frame - and you can assemble your greenhouse-architectural tetris from window frames of different sizes. And self-tapping screws and connecting compounds will be used: silicone sealant, cement and construction foam.

Stage I. Making the right foundation

If the greenhouse made from window frames will be located on clayey or swampy soil, it is necessary to make a cushion of gravel in advance, on top of which a layer of sand 10-15 cm high should be poured. After all, greenhouses and even a small greenhouse made from window frames are the heaviest, and they can easily sag on unstable soil. That is why it would be advisable to install pillars made of stone, brick, or even make them concrete at the corners of the greenhouse. In general, experienced experts advise starting the construction of a greenhouse from window frames only with the construction of the foundation - even if the future greenhouse will be located on “normal” soil.

So, a good foundation for a greenhouse can be a strip, 10x10 cm timber and sleepers.

How to make a foundation from timber

First you need to remove all fertile layer soil and compact the next layer of soil if it turns out to be loose. Next, all work should be carried out according to the following algorithm:

1. A layer of sand or crushed stone is placed and poured cement mortar by 15 cm.
2. You need to lay bricks or stones on the resulting “cushion” and fill it with cement mortar again.
3. A new layer of stones or bricks is laid so that they completely cover the seams of the bottom row.
4. On top of everything you need to lay 2 layers of waterproofing roofing felt.

How to make a strip foundation

It is better to build a greenhouse from window frames on a solid strip foundation. In its manufacture, you should also remove the top fertile layer of soil and dig a trench. If the soil under the top layer turns out to be weak and crumbling, then formwork will be necessary, but in a denser one you can do without it. And making formwork is not difficult - just put old boards along the walls of the trench and cover them with film to prevent concrete from adhering to them.

There is another way - a rubble concrete strip foundation. To do this, you need to lay large stones at the bottom of the dug trench and fill the space between them with smaller ones or crushed stone. Then fill everything with concrete and repeat the whole procedure again.

Stage II. Preparation of building material

Window frames must be prepared before installation. All hinges, handles and latches must be removed. It is generally advisable to remove old paint and treat exposed wood with a special antiseptic.

If during the work the frames will be attached to the frame with nails, then it is better to remove the glass first and carefully position it. After all, on the glass itself there may be microcracks invisible to the eye, which from the vibrations of a hammer can easily turn into large cracks. But those windows that will not be used in the greenhouse should be sealed, carefully sealing all the cracks - after all, you can make a greenhouse from window frames without any windows at all, like.

Stage III. Laying the floor in a greenhouse

For the floor in the greenhouse, you need to dig a space at least 15 cm deep. The entire base should ultimately be well leveled and compacted. You can pour concrete into the floor directly over this compacted earth for extra strength.

So, it is necessary to pour fine gravel onto the prepared base, in a layer about 10 cm thick. Next, the gravel is covered with plastic or roofing felt - this will be an excellent barrier to dampness and undesirable growth of weeds underfoot. On top of everything you need to pour 5-10 cm of good construction sand and compact it again. To ensure that the floor in the greenhouse is compacted well, you can use a vibrating plate. And finally, it’s better to lay the bricks closer together on the floor and fill them up construction sand so that all the cracks are filled.

Stage IV. Construction of frame and roof

The basis for a greenhouse made of window frames can be a frame made of boards of the same thickness as the window frames - 4-5 cm. In general, the frame will consist of an upper and lower frame plus posts. It is more expedient to make the bottom trim from two boards, because the height of window frames usually does not exceed 160 cm. There will be places on the racks long sides frames, thanks to which the gaps between them will be covered. It is advisable to attach the frames to the racks themselves with self-tapping screws, and to strengthen the frames in the frame, you can nail support bars to the inside of the racks. Moreover, the support bars can be safely made from boards of a slightly smaller cross-section.

In those parts of the greenhouse where there are not enough frames, polycarbonate sheets can be used. Best roof for a greenhouse made of window frames - gable and completely covered with polycarbonate. If a greenhouse is being built, then the roof can be made from them.

The height of the walls of such a greenhouse should be at least 170-180 cm. But the height of the greenhouse itself will depend on the angle of inclination of the roof slopes, which in turn is determined by the material used - for film it should be larger so that it does not sag, for polycarbonate - less. To prevent the film on the roof of the greenhouse from sagging at all, you can pre-stretch a nylon cord under it - a fine mesh, or initially purchase a reinforced film.

In order to build walls from window frames, you must first install vertical supports at the base. Using D-shaped notches in the cement, they need to be fixed, and wooden strips create a plane for installing the walls. The wooden sticks themselves should be nailed to the supports. And in order for the greenhouse roof to have the slope necessary for drainage, it is better to trim the upper edges of the supports.

Regardless of how exactly the old windows will be attached to the frame - with large screws or nails - between the frames themselves, it is imperative to seal all the cracks with polyurethane foam. Only then homemade greenhouse from old window frames it will turn out to be truly reliable and durable.

Once the frame for the walls is ready, it's time to move on to the roof - nailing the strips in the same way. The roof of such a greenhouse can be made into a traditional gable roof, especially if old windows are used for its manufacture, or a single-pitch roof. The second option is much more economical and easier, and in winter the light film roof can be removed completely if the greenhouse is used in very coldy If it doesn’t, then there won’t be any risk of a collapse due to a ton of snow.

Now you can nail the windows themselves to the frame. If nails are used, it is advisable to nail them in as often as possible to make the walls strong.

But the roof can be covered with film, polycarbonate, and partially with windows - but not completely, otherwise it will be difficult to avoid overheating in the greenhouse later. Of course, a greenhouse made from photo window frames is far from being as beautiful as those made from expensive polycarbonate, but in terms of functionality and durability it is in many ways superior to any semi-plastic structure.

Old wooden windows you don't always have to throw it away if you have it own dacha, and you are gardening. They may well be useful in order to independently make a good and inexpensive greenhouse or greenhouse for growing seedlings and various vegetable crops, will be an excellent alternative to expensive stationary greenhouses, which are sold in specialized companies. Constructing greenhouses from window frames with your own hands will cost much less than purchasing ready-made structures.

Window frames as a material for a greenhouse: pros and cons

Old windows perfectly transmit light, which is necessary for plants, and they also have high level strength, so a greenhouse made of them can withstand any type of precipitation.

Wood is a strong and stable material that is perfect for constructing greenhouses. And if new wooden structures are very expensive, then greenhouses made from old unnecessary window frames will cost mere pennies.

Old window frames for greenhouse construction

Greenhouses made from old windows have many advantages:

• All windows and vents open, which ensures constant ventilation of the room;
• Allows you to build a stationary, non-demountable or dismountable structure in a short time;
• You can grow vegetables, fruits and flowers all year round;
• Has excellent thermal insulation qualities;
• Allows the introduction of artificial lighting and heating into the room.

The only drawback is that it is often very difficult to find sufficient quantity frames of the same size to ensure that the structure is smooth and aesthetically attractive.

The difficulty of selection increases the construction time of the greenhouse.

Preparation for construction: diagrams, drawings and dimensions

Preparatory work begins with the selection of the required number of identical window frames. If they are completely different, then you will have to show all your skills and abilities in the field of architectural engineering and take measurements of each window separately, and then, having written everything down on paper, try to draw up a diagram - a drawing on paper.

Drawing of a greenhouse made from old window frames without a roof

This is the only way you can assemble not only a durable and reliable, but also an aesthetically attractive greenhouse, which is very important for creating the exterior of the whole personal plot. In addition, if you assemble a structure from windows different sizes, you will not be able to achieve the correct geometry, and therefore complete tightness of the room. Also, you will not be able to make a smooth and practical pitched roof.

Selecting a location

The location for building a greenhouse is very important point, since its future functionality depends on this. It is best to place the greenhouse on a flat area, well lit from all sides by the sun. But it is also important that the area is protected from strong winds, and there were no tall buildings or trees nearby that would create large and unnecessary shady areas for plants.

The greenhouse should be positioned in such a way that its longitudinal side is located from the north to the south.

Selecting a location for building a greenhouse from old windows

Soil selection

The ground under the greenhouse should be completely dry and clean. It is optimal when it lies under chernozem sand layer soil. Since window frames with glass are quite heavy, the soil must be dense and well compacted. Especially if our structure is erected without a solid foundation.

If you have clay terrain, then it will need to be well prepared. To do this, you need to make a blind area from medium gravel, and then make sand cushion about 10 centimeters thick, on which good fertile soil is poured.

It is very important to take into account the presence groundwater, which should be at a depth of more than one and a half meters. Soil with a high level of humidity is not suitable for building a heavy greenhouse from window frames.

In principle, to build a stationary greenhouse from old windows, any old frames with glass will suit us, and the main thing is that they should be the same as possible. We choose windows with intact frames (not eaten away by bugs and fungi), as well as intact glass, so that you don’t have to buy new ones, since they are not cheap.

Selecting window frames for greenhouse construction

It is necessary to remove all unnecessary metal elements from the window frames: hinges, handles, latches, etc. Then completely clean the window frames of old peeling paint and sand them with abrasive paper or a special sanding machine. We also recommend processing wooden frames an antiseptic substance that protects them from mice, rats, dampness and various insects.

If you want to attach the frames to a wooden frame using nails, you will have to remove the glass to avoid breaking them. And if you use ordinary screws, then there is no need to remove the glass. But at the same time, it is necessary to close all the windows so that they do not slam during operation. It is recommended to make the height of the greenhouse walls no lower than 1 meter 80 centimeters.

Calculation of the required amount of material and tools

In order to calculate required amount additional material you need to know the height and width of the windows. Depending on this, it is necessary to buy timber for constructing the frame, slats for creating sheathing and other materials.

It is also necessary to measure the width of all existing windows in order to have an idea of ​​how long the future greenhouse will be. In order to calculate the width, we recommend drawing up a drawing on which all passages and locations of the beds will be indicated in advance. Mostly, dacha owners make beds at least 1 meter wide. The width of the passage between them should be such that a small garden cart can be easily transported along it. Usually the width of the passage is also 1 meter, but it can be more or less depending on the wishes of the greenhouse owner and his ideas.

For work we will need tools and materials such as:

• Hammer;
• Nails;
• Screwdriver;
• Screws or self-tapping screws;
• Abrasive paper or sanding machine;
• Metal corners and plates;
• Polyethylene film;
• Boards - thickness 4 – 5 cm;
• Wooden beam 10x10 cm;
• Wood paint;
• Ruberoid;
• Bitumen mastic and antiseptics;
• Sealant and construction foam.

Step-by-step instructions with photos for building a greenhouse with a pitched roof and without a foundation

Since the window frames and glass are quite heavy, we cannot do without a foundation completely. Another thing is that we will not make it solid: concrete, stone or brick. We will simply make a base from a thick wooden beam, on which we will place our greenhouse.

1. First, you need to dig a narrow trench, about 15 cm deep, around the entire perimeter of the future greenhouse frame and fill it with small crushed stone. Compact everything well (you just need to pour water on the crushed stone and walk on it a little).
2. We put roofing felt on this crushed stone in two layers, and this is mandatory. You can use other waterproofing material, but roofing felt is more economical.
3. We place a timber approximately 10x10 cm in size on the roofing material along the entire perimeter of the structure. Before this, we treat the timber from below with bitumen mastic. This will increase its service life.

   Timber base for a greenhouse

4. We connect the timber at all corners from the inside with metal corners, and on the outside with iron plates.
5. When the so-called foundation is ready, we begin to build the frame for the future greenhouse. We will make it from boards about 4 thick – 5 centimeters. From these we need to make the upper and lower trim.

   Frame for a greenhouse from old windows

6. To do this, we install vertical posts along the length of all sides in the corners, as well as every 2.5 or 3 meters. The installation pitch of the racks must be calculated depending on the width of the window frames. In this case, it is better to make the bottom row from two rows of boards so that the height of the structure is much greater.
7. From above, all the racks must be connected in general design using a thinner wooden beam, for example 4x4 cm. It is the vertical posts that are the main volume of the frame.

   Upper framing device

8. We also fasten the entire frame together with iron corners and self-tapping screws so that the greenhouse made from old windows is as strong and rigid as possible.
9. We attach the prepared window frames to the vertical posts using self-tapping screws, and blow out the resulting cracks with regular foam. The frames also need to be secured on the inside by nailing support bars to them.

   Fastening the window frame to the frame with nails

10. If your window frames are too “low”, then you will have to make a two-tier frame, which will allow you to attach the frames to it not only vertically, but also horizontally. It would be good if we could find a sufficient number of single-leaf windows, with the help of which we would “raise” our greenhouse to the required height.

11. If you also make a pitched roof from window frames, then you should make a frame for the roof with a certain angle of inclination, since the glass in the window frames may not withstand a large amount of snow.
12. For a pitched roof, we make the rear pillars much lower to provide the required roof angle.

    Shed roof made of window frames

13. If you do not want to make a roof from window frames, then you can simply install a sheathing of wooden slats on the created frame and stretch plastic film. You can secure it to the frame using nails or a furniture stapler. This will be much simpler and easier, since the film can be removed for the winter so that a lot of snow does not accumulate on it.

    Construction of a roof from old window frames made of reinforced film

14. After the frames are screwed to the frame, it is necessary to insert the windows, secure them with glazing beads and lubricate the edges with sealant to prevent air movement inside the room.
15. Hooks or latches are screwed or nailed to the windows that will subsequently open. The rest can simply be nailed in and sealed with sealant.
16. We install doors. If the end of the greenhouse where the door will be installed is very narrow, then there is no point in installing window frames there at all. Maybe just the space between door frame and cover the frame with thick plastic film.
17. We make the door frame from timber. The door can be used as a regular interior door with or without glass. If dimensions allow, the door can also be made of high window frames.

Finishing: what color to paint and how to complement the structure

Window frames that have been cleared of old paint must be treated with various antiseptic and antifungal agents and, if desired, can be primed with a special wood primer. This is done to increase the service life of the “old wood”. Although I would like to note that old wooden frames have enough good quality, since in Soviet times everything was done “conscientiously.”

Then you can simply paint them with any paint you like, but usually choose the classic one White color. If you are a great esthete, you can fork out the cash and open all the frames with varnish. Such a greenhouse will look simply gorgeous.

The finishing touches exterior decoration- installation of handles on the windows that will open to ventilate the greenhouse and on the doors.

Floor construction

Inside the finished greenhouse, we pour a layer of fertile soil and arrange the beds at our discretion.

There are also other options, but they are more expensive.

Video: how to build a greenhouse from old window frames with your own hands

Based on our article, it cannot be said that a greenhouse from old window frames can be built in one day and costs nothing. But if you compare it with expensive factory stationary models, then it is no worse in its technical characteristics and the functions performed, and if you do everything as expected and put all your effort into building a really good structure, then it will serve you for more than one year. Such a greenhouse will not only allow you to grow your favorite vegetables and fruits, but will also become an integral part of your garden plot.

Spacious, "growth" greenhouse for growing early vegetables and seedlings is the dream of every gardener. Unfortunately, most often this desire does not coincide with financial capabilities owners of suburban areas - high prices for factory-made products, as well as the cost of building materials, can cool the ardor of even the most avid summer residents. To avoid unnecessary expenses and get a reliable and durable structure, just pay attention to the old window frames - perfect solution for making a greenhouse with your own hands.

Window frames as a building material: pros and cons

What home craftsmen come up with, breathing a second life into seemingly useless and unnecessary things. Today it is impossible to say who first came up with the idea of ​​building a greenhouse from used window frames, but the genius and simplicity of this solution deserves respect and admiration. Old windows are practically ideal option, because they have whole line advantages over other building materials:

• tightness ensured design features frame;
• high degree of light transmission due to the large glazing area;
• mechanical strength;
• rigidity;
• the presence of vents for ventilation;
• installation speed;
• the possibility of building a greenhouse without the involvement of assistants;
• ease of repair in case of damage;
• low cost.

The demand for plastic windows simplifies the search for material for building a greenhouse

Although the use of window frames has so many undeniable advantages, it’s still not worth idealizing this material. The weight of a wooden frame is, in fact, small, but when assembled with glass, the structure becomes heavy and requires a solid foundation - otherwise, ground movement can cause the structure to shift and damage the glass. Over time, the joints between individual elements dry out and require sealing, and the wood itself needs protection from harmful effects warm and humid environment, so be prepared for some repair work at the beginning of each season. However, these shortcomings are not so significant as to refuse such a simple and accessible way construction.

Design and design features

Like other similar structures, a greenhouse made from old windows is installed on a solid wooden or concrete base. The choice of foundation depends entirely on the frequency of use of the structure, the structure of the soil, the topography of the site and other natural factors. On durable earthen soils as a support it is enough to use boards 50–60 mm thick made of hard wood, while sand or sandy loam soil, as well as the risk of groundwater flooding, will require extensive concrete work.

In some cases, without durable concrete base not enough

Of course, individual window frames can be attached directly to each other, but to get a strong one, reliable design, you must first assemble a frame from wooden slats with a cross-section of at least 50x30 mm. This solution will significantly increase the rigidity of the structure, which means that the risk of damage to windows when frames are deformed during installation and during operation will be reduced. Another factor in favor of a wooden frame is the ease of installation of doors and a significant simplification of the roof structure, so it is not worth giving up a solid frame in order to save money - in the future this decision will justify itself many times over.

Greenhouse frame construction from used windows

Some home craftsmen also use window frames as roofing material, arguing that the light transmission of the greenhouse increases and the structure becomes truly monolithic. However, this is not recommended for several reasons:

• moisture flowing into cracks and gaps between the glass provokes increased rotting of the wood;
• possibility of roof damage from hail;
• low structural stability under snow load;
• an increase in roof mass reduces the stability of the greenhouse;
• It is impossible to predict how old window frames will behave over time, so such a roof is considered potentially dangerous.

At the same time, for the construction of not a greenhouse, but a greenhouse, the use of window frames as roofing material is more convenient and practical.

One of the greenhouse options for a suburban area

An important issue that should be decided at the design stage is the type of roof. Gable or arched structures Although they are more complex, they perfectly withstand winter drifts - snow rolls perfectly along their inclined surfaces. Concerning pitched roof, then it is much easier to install and requires less building materials, but you will have to pay for it by reducing the reliability of the structure.

An arched roof copes best with snow and rain

To connect individual frames and building elements to each other, you can use furniture corners and metal strips, which are fastened with self-tapping screws. Of course, preference should be given to parts made of galvanized metal - we should not forget about high humidity, which provokes rapid corrosion of fasteners.

Corners and metal perforated strips from the nearest building materials store are suitable for attaching window frames.

Most likely, the frames intended for the construction of a greenhouse will differ in size. To simplify the work, you will need to take the dimensions of the windows and number them, and then make a small sketch indicating the sizes and installation locations of individual mounting blocks. Of course, it is better to use windows of the same height - in this case it will be easier to install them, and the greenhouse will turn out not only even and symmetrical, but also beautiful.

When drawing up a working drawing, be sure to take into account the recommended sizes of beds and passages between them

The length of the structure can be any - it all depends on personal preferences, availability of space and building materials. But when calculating the width, it is necessary to take into account the location and number of beds, as well as the paths between them. To make it convenient to work in the greenhouse, its passages are taken equal to 0.5 m - this will allow you to move around with a small wheelbarrow. The width of the beds must be at least 1 m, otherwise the plants will not have enough space for normal growth.

Tip: a larger greenhouse can be built from the same amount of material if it is built as an extension to one of the outbuildings located on the site.

Getting ready for construction

At the very first stage, they select a place for the greenhouse, clear the site, and also prepare Construction Materials and tool.

Choosing a place

The success of the entire event depends on how correctly the location for future construction is chosen. Firstly, the structure should be illuminated by sunlight for as long as possible, so shaded areas near tall buildings or trees should not be considered. Secondly, it is better to install the greenhouse in places with minimal movement of atmospheric layers - reducing the wind load affects the stability of the structure and reduces heat losses. Thirdly, the fertility and condition of the soil must be taken into account. On bulk and unstable soils, it will be necessary to build a columnar or strip foundation, otherwise the walls will warp and the glass in the frames will crack.

The construction site should not be located in lowlands. Even if it is possible to avoid flooding or silting of the beds, the high groundwater level will have a detrimental effect on the plants.

Before starting to arrange the foundation for a greenhouse, stumps are removed at the construction site, the area is cleared of debris, and cleared of weeds and bushes.

Scheme for choosing a location for installing a greenhouse or greenhouse

What you need to build a greenhouse

Depending on the chosen greenhouse design, in addition to the window frames themselves, the following materials will be needed for construction:

• roofing felt;
• sand and crushed stone;
• cement;
• steel pipes with a diameter of at least 100 mm;
• hardwood boards 50–60 mm thick;
• timber 50x50 mm;
• slats 20x40 mm;
• metal corners;
• self-tapping screws;
• polyurethane foam;
• polyethylene film or polycarbonate sheets;
• protective and antiseptic agents for wood processing.

You can’t do without polyurethane foam when building a greenhouse from window frames - it reliably seals all joints and gaps

It is better to prepare the tools in advance, otherwise the process of pleasant creation may turn into a tedious search. Here's what you might need while working:

• an angle grinder (“grinder”) with a cutting disc for working on metal;
• sledgehammer;
• shovel and bayonet;
• containers or stretchers for carrying bulk materials;
• wood hacksaw;
• a set of screwdrivers or a screwdriver;
• hammer;
• drill with a set of drills for wood and metal;
• roulette;
• building level;
• pencil.

If you plan to install the greenhouse on a solid foundation, then you should take care in advance about how it will be prepared. concrete mortar- you will need a metal vat or a concrete mixer.

Preparing window frames

To build a spacious greenhouse you will need a lot of window frames, so it is better to look for materials for construction in advance. Of course, you can ask friends and acquaintances about their availability, but it is best to look through newspapers for free advertisements or contact one of the companies that install plastic double-glazed windows - where you can buy old windows for a nominal fee.

You can use a hair dryer to remove old paint.

Before starting construction, future Wall panels should be prepared. This will increase their service life and make the structure more attractive. To tidy up old window frames, you need to:

• dismantle fasteners and fittings (handles, latches, latches, hinges, etc.);
• with help grinding machine or scrapers to remove any remaining old paint. In some cases, you can use a special remover, for example, the compositions “Antikras-Sprint”, “Zebra SP-6”, “Household” and others;
• treat the frames with antiseptic agents that can protect the wood from fungi and insects;
• Secure unused windows with self-tapping screws. Gaps on mating surfaces should be repaired using sealant or putty.

Some online resources suggest exposing glass from frames, arguing that it may be damaged during installation. We do not recommend doing this under any circumstances. Most likely, the glass will require replacement just after unsuccessful dismantling, especially if during its installation wooden glazing beads were used, mounted on ordinary enamel or oil paint.

Step-by-step instructions for building a lean-to greenhouse from window frames with your own hands (without a foundation)

We offer you an algorithm for building a spacious greenhouse from old window frames. Its installation does not require a solid concrete foundation, so installation can be completed within two weekends. The structure has a pitched roof and is distinguished by its simple and undemanding design - any home craftsman can replicate it.

Base installation

A properly arranged wooden base will last at least 10 years only if certain conditions for its protection are met. Otherwise, the wood will rot much faster - a humid environment and contact with soil do not contribute to the safety of the boards.

So, you will need a beam with a cross-section of at least 100x100 mm from larch, oak, acacia and others resistant varieties tree. It must be treated with several layers of antiseptic agents and then tarred.

The place where the base will be laid must be prepared in advance. To do this, a trench up to 20 cm deep is dug along the perimeter of the structure, in which a sand and crushed stone cushion is installed. The drainage layer will remove excess moisture and promote durability wooden base. To achieve its maximum durability, the trench is covered with a layer of roofing material and only after that the timber is laid.

The wooden base of the greenhouse is protected from moisture in any available way.

The individual elements are attached end to end using metal strips and corners, as well as using the “half-tree” method. To do this, indentations are made on the mating parts using a saw, hammer and chisel, after which they are connected to each other using nails or self-tapping screws. Usually, additional fastening no foundation to the ground is required - the mass of the window frames will be enough for the structure to successfully withstand the wind. However, for reliability, pipe sections 0.5–0.6 m long can be driven into the ground from the inside of each corner, attaching them to the beam using metal strips.

One of the ways to attach a wooden greenhouse base

For significant differences in elevation, as well as in lowlands, use columnar foundation. It is equipped using metal pipes large diameter or by pouring concrete blocks. Boards laid on such posts are secured using dowels or metal corners, and the gap between the base and the surface of the area is covered with clay and thoroughly compacted.

Walling

The assembly of the greenhouse begins with the construction of the frame. To do this, a lower frame made of timber is laid on the base. You can use any type of lumber, it is important that their cross-section approximately matches the thickness of the frames. Most often, they take inexpensive pine beams with a cross-section of 50x50 mm, the individual elements of which are fastened with furniture corners or the “half-tree” method.

The frame of the greenhouse made of window frames includes vertical posts and horizontal lower and upper trim

Vertical posts are installed at the corners of the frame, as well as every 2–3 m (the distance depends on the width of the window frames). Their length is chosen taking into account the height of the windows, as well as focusing on one’s own height - it must be comfortable in the greenhouse, otherwise work “for the soul” will turn into punishment. The greenhouse has a pitched roof, so the posts on one side should be 0.5–1 m higher - this will provide the roof with the required slope.

For a small greenhouse, vertical posts installed at the corners of the structure will be sufficient.

At one end of the greenhouse, vertical posts are installed so that the resulting opening can serve as a door frame. Perhaps the width of the structure will not be enough to cover the remaining space with window frames. In this case, the space between the door and corner posts covered with plastic film.

Above vertical elements The structures are connected to each other by horizontal strapping using the same self-tapping screws and metal corners. Unlike greenhouses covered with plastic film, structures with walls made of windows do not require reinforcement of the frame. The structure will acquire the necessary rigidity after the wooden frames are installed in place. However, there is no need to rush to install them - you should first make the roof.

The construction of a pitched roof for permanent structures is shown in the figure. In our case, there is no need to install additional racks and rafter legs - they, like ceiling beams, will be needed only in greenhouses more than 6 meters wide. In the greenhouse under consideration, the roof support in the lower part is top harness frame, so all that is needed is to attach the timber to the ends of the long posts and install the rafters. The best material for them is not timber, but a board installed “on edge” measuring 50x100 mm. It will not allow the roof to sag even with a significant snow load.

Shed roof design

If the greenhouse will be covered with film, then the rafters should be sanded and then covered with fabric or foam rubber. They will save roofing material from damage.

The rafter legs are mounted to the horizontal frame in the places where the racks are installed, at a distance of no more than 1 m from each other. For fastening polycarbonate sheets 20 mm thick slats can be laid perpendicular to the rafters, while polyethylene film does not require additional sheathing.

One of the ways to attach a rafter leg

We have already said above that it is not recommended to use window frames as a roof - film or polycarbonate is much safer, and they are also easier to install. When choosing polyethylene fabric, preference is given to heat-stabilized materials - they are practically not susceptible to the destructive effects of ultraviolet radiation. The best option is considered a special reinforced film for greenhouses. As a rule, such coverage is enough for 2-3 seasons.

It is convenient to use thin slats or window beads to attach the film.

Mount roll material with a little tension, so this work is best done together with a partner. To attach the film, wooden planks are used - they provide sufficient pressure and prevent damage to the polyethylene. An overlap is made on both sides of the greenhouse, which will be sufficient to eliminate the gaps between the frame framing and the longitudinal beams of the roof. The gable openings are also covered with polyethylene or triangular polycarbonate panels. By the way, the latter option is more preferable due to its durability - it will not be necessary to renew the coating for many years.

Fixing window frames and installing doors

After constructing the frame and roof, they begin to install the window frames, checking with the previously developed drawing. Windows are installed with outside frame, after which they are fixed to the beams and to each other using nails, self-tapping screws, furniture corners and perforated metal strips. During installation, the frames are oriented so that the windows open outward. Excessive vibration that occurs during nailing of frames to the frame threatens to crack the glass. To reduce the impact load, through drilling is performed in the right places. Their diameter should be 0.5–1 mm smaller than that of the nails used - a slight tension will only benefit the connections.

The gaps between the individual elements of the greenhouse are filled with polyurethane foam. After hardening, excess polyurethane sealant is cut off flush with the frames, and then plastered or covered with thin wooden strips. This will protect the sealing layer from the harmful effects of ultraviolet radiation and excess moisture.

A greenhouse made from old window frames is ready for use.

The door frame is made of wooden beams and attached to the frame using conventional metal hinges in such a way that the door opens towards you when visiting the greenhouse. Considering the increased operational load, it is better to sew up the sashes not with film, but with a polycarbonate sheet. When building a large greenhouse, you can use ready-made balcony door. Of course, in this case doorjamb must be reinforced, so it is made from a 50x100 mm board with a selected quarter.

Latch bolts and stops are mounted on the door and vents, which will allow them to be held in place. open position for ventilation of the internal space.

The success of a greenhouse mini-farm will depend both on the quality of the structure itself and on its internal filling. A properly equipped greenhouse will make it possible to work easily and conveniently, while maintaining positive mood. And this, as you know, is half the success in any business.

One of the most important stages When building a greenhouse, the construction of beds is necessary. If the site is located on fertile soil and is not subject to flooding, then it is enough to install fences and pour a mixture of humus with peat and chernozem inside. If there is a danger of flooding, as well as in places with high groundwater levels, paths and beds are made only after drainage has been installed on the floor.

Arranging beds in a greenhouse

For these purposes, soil is removed to a depth of 20 cm, after which the floor is covered with a 10-centimeter layer of fine crushed stone or granite screenings. The remaining space is filled with sand and compacted thoroughly. After this, the beds are formed, installing border tape or strips along their perimeter flat slate by creating frames from boards or doing brickwork. Inner space covered with fertile mixture. Its thickness should be sufficient to grow the selected garden crops, therefore this parameter is not standardized. For some, a layer of 20–30 cm is enough, while others prefer not to bend over, creating so-called raised beds up to 70–90 cm high.

The paths inside the greenhouse can be covered with crushed stone or sawdust - this will effectively remove moisture. The disadvantage of such a coating is that it creates difficulties when moving greenhouse equipment and complicates cleaning. It's best to spend a little money and lay out the tracks paving slabs, concrete or make a boardwalk. In the latter case, oak logs and hardwood boards are used. Before installation load-bearing elements the structures must be tarred, and the platform itself must be treated with an antiseptic and coated with oil paint.

In a properly equipped greenhouse, work is a pleasure

So that the greenhouse is not only a functional unit, but also has a complete appearance, All wooden parts should be painted inside and out. This will not only make the structure more attractive, but will also make it more durable.

Video: features of building a greenhouse from old windows

Building a greenhouse from old window frames is not difficult at all. For this you will not need either expensive materials or a specific tool - only your desire and imagination. Having equipped it with a system drip irrigation, by installing heating and lighting, you can achieve excellent results in growing early garden crops and get food on the table fresh vegetables in any season.

After renovating the house, all that remains is to replace the old window frames with new plastic windows. Well, what should we do with the old frames? What to do with them? If you have a small plot of land, make a greenhouse out of old windows with your own hands!

1. The main condition for good growth plants this is light. The future place should be open; there were no trees nearby that would block the light of the sun.
2. The second condition is the presence of groundwater close to the surface. Our greenhouse is quite heavy (this, by the way, is a minus) and the close location of groundwater can simply flood our greenhouse.
3. The third important condition is the location of the edges of the greenhouse from east to west. This is done to ensure that the plants receive the maximum possible amount of sunlight.

By the way! A greenhouse made from old windows (frames) has the maximum possible light transmittance, which distinguishes this material for building greenhouses from many others (polycarbonate, polyethylene, etc.).

Plan the size of the greenhouse based on:

Main track. Will be used to approach plants for the purpose of maintenance and harvesting. Focus on a path about 60-70 cm wide. If it is smaller, then it will be uncomfortable for you to walk along it and you may end up touching plants with your feet.

Garden bed. Place for planting plants. Optimal size the beds are up to 1 m. But this size can be adjusted up or down based on what you are going to grow.

Foundation

To protect a heavy structure from shrinking into the ground (and a greenhouse made from window frames is undoubtedly heavy), you need to build a strong foundation.

In addition to shrinking the frame into the ground, the foundation slightly insulates the greenhouse soil, protecting the plants from cool weather conditions.

Foundations may be different. Concrete, metal and brick. We will focus on the most common and reliable one, this is a concrete foundation, namely a strip or monolithic type.

Monolithic type of concrete foundation is not often done, due to high flow rate materials, which is very unreasonable today.

Let's take a closer look at the strip foundation. Conditionally, construction (installation) strip foundation can be divided into stages of work.

Preparing our old window frames

In order not to waste a lot of time, it is better to prepare old window frames for installation. What to look for?

Removing foreign elements that are not useful to us. Handles, canopies, latches, etc.

Replacement of cracked glasses with new ones. Everything here is simple and clear. We don't need glass falling into our cucumbers from the wind. We change cracked glass without looking at the new ones!

Removing old peeling paint. Ultraviolet does its job, but there should always be protective paint. It protects wooden elements from exposure to the sun, thereby prolonging its service life. For long-term use, you only need to paint the wooden elements every or every year. If the old paint holds up well, then you don’t have to remove it all, but just go through it superficially (disturb upper layer old paint) with a piece of sandpaper. Thus, we increase the level of “adhesion” of the new paint to old surface. To explain in simple words, we use sandpaper to make micro-scratches that will cling to new paint. Also, keep in mind when applying the paint should not be very thick or, on the contrary, liquid (meaning dilution with a solvent). Which paint should I choose? Yes, the simplest one, the same PF 115 will do. Please note that PF come with different numbers, so for our needs we need exactly 115 (there should be a note on the can that the paint is for exterior use).

I apologize for writing so much about painting. The experience of a painter and sandblaster in industrial mountaineering does not allow him to write just two words.

If the greenhouse elements are fastened (frame to frame) using screws, then the glass does not need to be removed. If you decide to fasten with nails, think again, if you haven’t changed your mind, remove all the glass! If you are too lazy, go get a bucket and collect the fragments in it. And then buy new glass to replace the broken ones.

Installation of the greenhouse frame

The frames are screwed to a special frame (skeleton). It can be made from timber or boards. If it is a timber, then the diameter should be 5x5 cm. If it is a board, then its thickness should be at least 4 cm.

Installing window frames on a wooden frame

There is nothing complicated here. The frames are attached to the vertical posts of the frame. We start, of course, not from the middle, but from the corner, and move towards another corner. We foam the joints between the frames with polyurethane foam. It is better to use screws to attach frames to the frame. If you do this with nails, the structure may become loose over time.

Roof

For the roof, you can use film or polycarbonate.

The first is cheaper, the second is more reliable.

If you choose cheaper. Before each cold weather, we remove the film and put it on again in the spring.

It is ideal to make a gable roof from polycarbonate.

It is made in the same way as a greenhouse, first a wooden frame, then polycarbonate is attached.

In this video, the owner built a small greenhouse from window frames. The roof was made from ordinary polyethylene film.

And in this video, the owner built a rather large greenhouse (greenhouse) from old frames. Gives advice and recommendations on how not to get confused during construction.
