How to make a house from OSB with your own hands, without losing quality and saving money? Indeed, for the same area, the cost of construction, depending on the materials used, can vary greatly. And with some construction technologies you can’t do without renting powerful equipment. The most inexpensive, fastest and in a simple way Frame house construction made from sandwich panels or OSB boards is considered.

OSB or oriented strand boards consist of 90% wood chips. The remaining components are binder waterproof resins. Building panels are obtained by pressing large fragments of wood coniferous species, aspen and larch. The size of the chips is up to 15 cm. Inside the future product, it is laid in three rows. Outer layers are placed parallel long side slabs The middle layer is perpendicular. The pressure in the press is so strong that the fibers interpenetrate. This guarantees high strength to the final product.

The resulting material is sometimes called improved wood. It is lightweight and easy to handle. Unlike natural solid wood, OSB does not burn or rot; there are no knots or voids in their structure that reduce its stability. In terms of its characteristics, it surpasses chipboard sheets, MDF or plywood. These panels hold fasteners well: bolts, nails, dowels.

The use of phenol in binder mixtures raised the most questions among consumers. But now many manufacturers have begun to switch to polymer resins, which are completely safe for health. Such a product is marked with the words “ECO” or “Green” on the packaging.

Construction from OSB panels

In private house construction, 4 types of OSB panels are used, differing in water resistance, strength and price.

Moisture resistance depends on the binding adhesive, and strength depends on the mutual placement of chips in its structure. Lamination and varnishing of the surface provides additional resistance to all types of influences. Such slabs can be used in the construction of formwork, and repeatedly.

Type 1. OSB-1 has little resistance to stress and is hydrophobic. They are taken for finishing when interior work ah or furniture making;

Type 2. OSB-2 is also resistant to moisture, but is much stronger and therefore suitable for the construction of partitions, false ceilings, that is, those parts where there are no heavy loads and the possibility of getting wet;

Type 3. OSB-3 is suitable for creating external facades, they are high-strength and moisture-resistant;

Type 4. OSB-4 is very durable, used for assembly load-bearing elements walls and roofs, give the structure rigidity.

A house made of OSB boards is made mostly of type 3 products. Height – up to 3 floors inclusive.

Construction Features

1. The work takes 2–3 weeks without the use of heavy machinery.
2. The building is not even built, but assembled like a construction kit from ready-made parts made at the factory. They are made to order, specific project. This means that there will be no unexpected expenses and urgent additional purchases of missing building materials, as well as difficult-to-sell balances after completion of all stages.
3. OSB boards are much cheaper than bricks or foam blocks.
4. The frame building weighs a little, almost 5 times less brick house the same cubic capacity. Therefore, the structure does not require a massive and expensive foundation.
5. The OSB-3 box can already have layers of thermal insulation installed during production. This is how SIP panels are made. Then additional insulation no need. Saved inside comfortable temperature at external differences from -40 to +40°C.
6. The smooth surfaces of the panels do not require priming or leveling before finishing decorative coating on the walls or ceiling. Unless you need to putty the joints.
7. If the technology is followed, houses made of OSB do not shrink or warp.

OSB boards are a universal material and can be used at any stage of construction.

Foundation. Laminated or veneered sheets can be used as foundation facing panels, assembled on a frame made of beams. They are fastened with ties made of steel wire or thin reinforcement.

Floor. The slabs are laid on the logs with the long side perpendicular to them. A technological (dilation) gap of 3 mm is left along the perimeter of the panels. It is needed to compensate for thermal expansion or other deformations. There is also a 12 mm gap between the walls and the floor. The sheets themselves are fixed using a tongue-and-groove profile and reinforced with mounting adhesive for reliability.

The connection of the short sides must always take place on supports. An additional layer of waterproofing is stretched under the flooring adjacent to the ground. The pitch between the lags is determined by the thickness of the material:

Walls. Oriented strand products can be mounted both vertically and horizontally. When assembling the walls, 12 mm thick sheets are used. They rest on bars with a pitch of 400 and 600 mm. Between the slabs, as well as in places adjacent to doors and window openings leave gaps of 3 mm. For insulation from the outside, the building can be insulated with mineral wool.

Roof. The sheets form continuous sheathing, on which it subsequently spreads roof covering. Installation begins along the ridge, wood panels are laid similarly to the floor. Each sheet is fastened so that there are two supports underneath it. The joints of the slabs should also be on the rafter joists.

So that the roof can withstand snow load, select the spaces between them depending on the thickness of the slab:

When working at any stage, take into account the main rule of building a house from OSB: the connections of the support beam and panels must be sealed. The joints and corner parts are fastened with self-tapping screws in increments of 15 cm.

Thanks to the properties of sheets made of oriented shavings, the structure does not rot and is not undermined by insects. He is also not afraid of fires. According to experts, the service life of a house made from OSB-3 panels is the same as from brick.

We invite you to watch a video about building a house from OSB panels.

house made of OSB boards

The abbreviation OSB translates as oriented strand boards; the building material is ideal for construction according to frame technology and provides high performance, since during manufacturing the sheets are treated with resin.

Installation of OSB boards

OSB boards have the following layers:

• inside the chips are located transversely;
• On top, the chips are located longitudinally.

If a layer of insulation is laid between these layers, these will already be sandwich panels. Usually the role of insulation is performed mineral wool, polystyrene foam or polyurethane foam.

Types of OSB boards for the construction of frame houses

types of OSB boards

Group 1: used for arranging partitions between rooms. The boards have low strength and cannot be used at high humidity.

Group 2: used for load-bearing walls in a buiding. They have low resistance to moisture.

Group 3: suitable for construction external walls, because it is not afraid of excess moisture.

Group 4: sheets of this type are not purchased very often, although they have increased strength.

These particle boards, depending on their purpose, are indispensable in the construction of houses using frame technology.

Pros and cons of OSB boards when building a frame house

Since these panels are made of wood chips, their characteristics are similar to fiberboard and chipboard. However residential buildings are built precisely from these slabs, since they have the following undeniable advantages:

1. High strength.
2. For production, environmentally friendly raw materials are used, corresponding sanitary requirements and standards.
3. Easy to handle, transport and install.
4. Low cost compared to other types of building materials.
5. Slow flammability and combustion;
6. Elasticity and flexibility;
7. Resistance to insects, fungi and bacteria.

However, OSB boards also have some negative properties. For example, it is recommended to build walls from the panels of the last two groups from the outside. The fact is that they contain a resin containing toxic substances.

Be sure to ask for a certificate for this material and be sure to study all instructions.

Step-by-step algorithm for installing an OSB frame

construction frame house from OSB boards

OSB boards are a modern and quite popular material for construction. The whole process must begin with the construction of the required type of foundation: strip, monolithic or pile. The choice of foundation should take into account the construction site, ground freezing indicators, as well as data on what level the The groundwater. But in most cases they install pile foundation, since the weight frame structure small.

After the foundation has been laid, it is necessary to determine the quantity and type building material: sandwich panels or OSB panels 3-4 groups. Yes, you can use panels of the first two types, but you need to additionally insulate the structure. Over the entire area of ​​the base of the building you need to attach support board, subsequently installing the selected type of OSB panels on it. The frame elements are fixed using self-tapping screws and grooves.

The assembly of a frame house should begin from the corner of the future structure. To connect OSB sheets, it is necessary to use nails, horizontal grooves and a vertical beam. In particular, it is necessary to correctly join panels of building material in the corners so that gaps do not form.

When using simple OSB boards, the interior of the house must be insulated. Waterproofing is not needed here, because groups 3 and 4 of the material have good performance moisture resistance. Upon completion of thermal insulation, you can begin finishing the surface of the walls, for example, with plasterboard. After assembling the frame, partitions between rooms can be installed using group 2 particle boards.

Using OSB boards, you can build both walls and a roof (group 3 of OSB panels). Initially, rafters and supports are installed, wooden sheathing from bars, and panels are already attached to them with nails or screws. It is important to decide in advance on the location for the chimney so that there is the required distance around it.

Our step by step instructions We will divide the construction of a frame house into several stages:

It is worth noting that each stage of building a frame house deserves a separate article, in addition to everything, if we describe everything possible options foundations, roofs, etc., it could be a whole book. In this regard, to improve readability, some steps in construction are described in detail in separate articles, but here - only what concerns the features specifically frame house.

Step No. 1: Preparatory work for the construction of a frame house

Preparatory work for the construction of any house are the same and include:

1. Site preparation
2. House marking

Site preparation

First, you need to clear the area of ​​vegetation, if not all, then at least the place where the house will be built. This will greatly facilitate the marking and allow you to make it more accurately.

If the construction site has a large slope, then, depending on the type of foundation and desire, it can be pre-leveled using special equipment.

Attention! Do not neglect this procedure, spending 1-2 hours on clearing, in the future you will make your work much easier, and measurements in the grass may be subject to a large error.

House marking

Marking is a very important stage, because the layout and evenness of the corners of the walls depends on it. If the marking is inaccurate, it will be very difficult to correct this error in the next stages.

Marking the foundation of a frame house, as well as any other, as a rule, includes preliminary placement of pegs (all external walls are marked), as well as marking of all interior walls.

If you want to learn how to correctly mark the foundation for a house with your own hands, and so that all the walls and corners are level and correspond to the project, I advise you to read my article about this. Given the large amount of information, it had to be submitted separately.

Step No. 2: Do-it-yourself foundation for a frame house

The great advantage of a frame house is that almost any type of foundation is suitable for its construction. The only limitation is the type of soil on the site and your capabilities.

It is worth saying that laying the foundation for a frame house with your own hands deserves separate topics of discussion and is included in separate articles. Moreover, there are several types of suitable foundations, and it’s up to you to decide which one to choose.

Here I will tell you in a nutshell about suitable foundations for a frame house, and in what cases each of them is used, and also give links to their detailed description.

The most common type of foundation for a frame house is a pile-screw foundation. This is practically the simplest and cheapest option for such a house, especially since installing a pile-screw foundation is not difficult even with your own hands.

Such a foundation is suitable for almost any soil, except rocky ones. Particularly suitable for swampy soils, where compact soils are located deep and other types require huge costs.

In general, all the pros and cons of pile-screw foundations are discussed in another topic that will help you decide on the choice of support for your home.

Shallow strip foundation

Shallow strip foundation, is also used for construction quite often. This is due to the relatively low cost of laying it, as well as the possibility of using concrete floors in the house.

Such a foundation, due to its relative fragility, requires strict adherence to laying technology.

As a rule, shallow strip foundations are used in good soils, and is strictly contraindicated on the basis of very high level groundwater and marshy soils.

Slab foundation for a frame house

IN Lately, slab foundations are becoming increasingly popular for building a frame house with your own hands. Despite its considerable cost, it has obvious advantages, such as versatility, reliability, durability, and it can also be used as a subfloor in the house and not spend money on it separately.

Often, instead of the classical monolithic slab use a slab foundation with stiffeners. This allows you to save a little on laying, and also strengthens the entire structure as a whole.

Step No. 3: Installing the floor of a frame house with your own hands

The floors in a frame house are not much different from the floors of other types of houses and can be wooden or concrete. The choice depends entirely on the type of foundation, capabilities and desires.

In this step by step instructions We will consider in detail only the wooden floor, concrete - in a nutshell, since it is used less often, and it is not possible to fit everything into one article.

Concrete floor installation

It is worth noting that a concrete floor in a frame house is installed in cases slab foundation, or tape. With a slab, everything is clear - the slab itself will be the floor of the first floor.

But if the foundation is strip, the concrete floor is made of lightweight concrete, such as expanded clay concrete, for example.

Wooden floor installation

Let's look at the construction of a wooden floor using the example of a pile-screw foundation. For tape, in principle, everything is done exactly the same, except bottom trim, it may be made of thinner timber. But first things first.

Tying the foundation of a frame house

The installation of a wooden floor begins with tying the foundation. As a rule, the piping is made from timber 150x150 or 150x200, depending on the thickness of the wall and the distance between the piles. The greater the distance, the thicker the timber should be to avoid sagging.

The strapping is necessary, firstly, in order to give rigidity to the foundation, secondly, to evenly distribute the load on the foundation, and thirdly, it will serve as a support for the future floor of the frame house.

In order to easily carry out the tying process with your own hands, we will divide it into several stages:

1. The timber is laid out along the perimeter of the foundation, the length of the walls and diagonals are checked. At this stage, the final and accurate marking of the walls is carried out, according to the project. By the way, don’t forget about waterproofing, which we put under the harness in the form of roofing material.
   
2. The next step is to outline the joining points of the timber; they should be located on the pile, since these will be the weakest points that should not “hang”. This applies to houses whose walls are longer than the length of the purchased beams.
   
3. The timber is joined with an overlap of 20-30cm, as shown in the photo. To do this, so-called “locks” are cut out from the end.
   
4. The corners fit almost exactly the same way. This is clearly visible in the photo.
   
5. The beam is attached to the foundation using bolts or studs. To do this, it is necessary to drill holes both in the head of the foundation and in the beam itself. For ease of further installation, protruding parts - bolt heads or nuts with studs - must be deepened. The joints are additionally punched with nails measuring 150 mm or 200 mm, depending on the size of the timber.
   
6. Once the perimeter is ready, we move on to the final step - tying the foundation under the internal walls of the frame house. This beam, to the already installed external one, is attached in the same way. For reinforcement, you can additionally use fastening metal corners.
   

When the piping of the foundation of the frame house is ready, we proceed to next stage our instructions for the construction of a floor frame.

Floor frame in the house

It is worth noting that already at this stage it is advisable to provide for all communications entering the house, such as water and sewerage. Electricity and gas can be supplied later, but if everything is foreseen in advance, it will be much more less problems after.

The next step is to install the joists on top of the trim. If the distance between the supports is about 4 meters, then it would be better to use timber measuring 100x200mm or 100x150mm. You can use a 50x200mm or 50x150mm board, sewing them together in twos.

If the distance is less than 3 meters, you can use a board measuring 50x150mm or better 50x200mm.

Installation of logs is a simple stage in assembling a frame house, but there are some nuances that must be covered in these instructions:

Do-it-yourself waterproofing and insulation of the floor of a frame house

It is worth noting that waterproofing, as well as vapor barrier, must be installed with an overlap, according to the instructions for the material, while preventing moisture from entering the insulation, both from the outside and from the inside. And the insulation itself is laid tightly, without gaps.

So we have looked at the instructions for installing the floor of a frame house, now it’s time to start working on the walls.

Step No. 4: Construction of the walls of a frame house

Our next step instructions I will be installing the walls myself. Just like with the floor, we will fasten all the boards and beams with nails and (or) mounting metal corners, some fastenings can be made with studs.

It is worth noting that almost the entire frame is assembled from boards measuring 50x150mm or 50x200mm, depending on required thickness walls and the required thickness of insulation.

Some people think that it would be better to install timber in the corners of a frame house, but this is not entirely correct, and I’ll tell you why a little later, during the installation process.

So, let's start assembling the frame of the walls of the future house.

For better understanding and assimilation, we will divide our instructions for constructing the walls of a frame house into several stages:

1. Assembling the walls of a frame house. Windows and doors
2. Installation and fastening of walls vertically on site

Assembling the walls of a frame house with your own hands. Windows and doors

We will assemble the walls on the already finished floor of the frame house, this is the most convenient option. But we must take into account that in this case, it is necessary that all dimensions be accurate so that the walls do not turn out to be longer or shorter than the already installed floor.

To make it clear what I'm talking about, first look at sectional wall of a frame house , and then I will tell you everything in order.

Now let’s look at step by step how to assemble all the walls of a frame house with your own hands:

1. First of all, we need to decide on the ceiling height in the house. Let's assume that the height of the rough ceiling will be 280cm. Means vertical racks frame walls should be 280-15=265cm. The diagram shows where the 15 cm came from.
   
2. The distance between the racks, as a rule, is selected based on the width of the insulation sheet, as a rule, its width is 60 cm. If the insulation is on a cotton basis, then the distance is made less by 2 cm, for a tighter contact.
   
3. The top and bottom boards of the wall are laid out on the floor and the places where the vertical posts will be nailed are marked. Then the racks themselves are laid out and pierced with 120-150mm nails. You can additionally fasten them with corners.
   
4. It is worth noting that each wall will be smaller in wall thickness than the length of the floor. This is clearly visible in the diagram.
   
5. If the length of the wall is greater than the length of the board, then the wall is assembled from several parts. This is also done in cases where there are few helpers, because the whole assembled wall will have a lot of weight.
   
6. As a rule, to add rigidity to the entire structure, jumpers are mounted between the racks. There are no strict rules on the number and frequency of installation, it all depends on the length and height of the walls, but usually they are installed one or two per space between the racks. The second option is better and is visible in the photo; in the case when they are made one at a time, they are mounted in a checkerboard pattern (one at the bottom, the next at the top). This can be done later, when the walls are installed. Most often, jumpers are made with the expectation that they will serve as a joint for plywood or osb boards, depending on further work.
   
7. Window and door openings in the wall of a frame house are arranged as shown in the diagram.
   
8. This is what it looks like “live”.
   

The most common mistake when assembling the walls of a frame house is that many people forget to take into account the thickness of the board when calculating, thus the wall is not as long as we would like.

Putting the walls in place

It is worth noting that when assembling walls, it is necessary to use a cord, pulling it from one corner to another, otherwise the corners will be even, but the walls will not.

Top trim and structural reinforcement

So, the wall frame is assembled, now you need to make top harness from the same board as the walls.

The top trim is necessary, first of all, for stronger adhesion of the corners, and will also give unity to all parts of the frame walls and distribute the load between them.

To do this, it is necessary to pierce the board with 120-150mm nails over the walls, along the entire perimeter, including the internal load-bearing ones, so that all joints are covered with an overlap of at least 25-30 cm. Except for the corners, where the overlap will be equal to the thickness of the wall.

The next step in our instructions will be to strengthen the entire structure as a whole. There are several options, the most common is reinforcement using plywood or OSB board.

As a rule, having pierced one side along the entire perimeter (internal or external) with sheets of OSB boards, the frame of the house already becomes very rigid.

Internal partitions of a frame house

The construction of internal partitions is almost no different from the construction of external walls, except that they have more lenient requirements in terms of thickness and insulation.

1. Internal partitions, unlike external walls, can be made thinner. Everything will depend on preferences and comfort in terms of sound insulation.
2. The insulation inside the partitions will serve primarily as a sound-absorbing material rather than as thermal insulation.
3. Internal partitions can be insulated without waterproofing and vapor barrier materials.

These are all the main differences between internal walls and external ones, otherwise they are arranged in exactly the same way.

Step No. 5: Roof of a frame house

The roof of a frame house is practically no different from the roof of other houses, be it concrete, brick or any other. I’ll even say more that installing a roof for a frame house will be less labor-intensive than, for example, for a block or brick house, because its fastening to the walls will be much simpler.

It is worth noting that building a roof is a very responsible process, but if you do not have a complex house layout, then you can easily do it yourself.

Building the roof of any house, including a frame one, is a very large topic with many nuances. Firstly, there are many types of roofs, and it is not possible to describe everything in detail in one article. Well, secondly, in order not to confuse you, I will probably move this topic to a separate article.

Step No. 6: Insulating the frame house

Now we have come to the final stage of building a frame house - its insulation. Everything needs to be insulated - floor, walls and ceiling.

You can read more about insulating a frame house with your own hands in another step-by-step instruction; here we will discuss only general points.

When choosing insulation for the walls of a frame house, it is necessary to take into account not only the characteristics of the insulation itself, but also the characteristics of wood, with which not all types of insulation will interact well.

Here small instructions for insulating a frame house with your own hands:

1. Outside, over the OSB sheets, a special waterproofing membrane is stretched. Which side should be in the instructions for it.
2. From the inside of the house, between the studs, insulation is laid in several layers, depending on the requirements for the house and the thickness of the wall. Each layer is laid overlapping the joint of the previous one to avoid cold bridges.
3. Floor insulation occurs in the same way.
4. It is better to insulate the ceiling from the attic, having previously filled the vapor barrier film from below onto ceiling beams and hemming them with board or plywood.
5. After laying the insulation, it is necessary to fill a vapor barrier film over it; it will protect the insulation from moisture from the inside.
6. Depending on needs and further finishing works, on top of the film, sheathing material is placed on the walls - boards or slats, but most often - OSB sheets, on top of which, in the future, finishing is carried out.

As you have already seen, there was a lot of text. But, I believe, all stages of construction were described in detail here DIY frame house, despite the fact that some points were included in separate topics, but this is only for your convenience.

I hope that by following these step-by-step instructions, you will be able to minimal costs get a warm, cozy and reliable home.

Materials made from wood waste have all the positive qualities of natural materials and a lower cost. Modern technologies made them stronger and more resistant to water and fire. Frame construction is becoming more and more popular. People like a house made of OSB boards, it is warm, light, and retains the smell of the forest for a long time. By ordering parts in accordance with the project, you can build a house with your own hands without lifting equipment and wet work.

How to build a house from OSB?

Improved qualities of natural wood in OSB panels

Wood surpasses all others in its qualities that create comfort in the home. natural materials. Its disadvantage is swelling from water and fire hazard. Rodents and insects love to live in warm walls, prematurely destroying them.

In the production of products from solid wood a lot of waste remains:

• small pieces of wood;
• branches;
• wood chips;
• sawdust;
• shavings.

They are sorted and combined different ways and pressed. The result is panels that take the best qualities of wood.

The production of OSB panels uses large chips, accounting for 80% of the mass of the slab. It is laid in layers, orienting the direction external parties along the leaf. The internal chips are arranged transversely. Perpendicularly oriented fiber eliminates warping and shrinkage of the panels. Pressing and impregnation with synthetic resins makes the material more resistant to fire. It does not ignite and does not support combustion, but it chars and collapses. This does not release toxic substances.

OSB panels for house construction

In construction, there are 4 groups of OSB panels based on strength and moisture resistance. The table shows the main use of each type.

OSB board class	Strength	Moisture resistance	Application area
OSB-1	low	low	furniture making, internal partitions, interior elements
OSB-2	average	low	only in dry rooms
OSB-3	average	high	outdoor and interior lining walls, partitions and finishing in wet rooms, bathrooms
OSB-4	high	high	all types construction work, including plinths and basements, reusable formwork

Walls made of OSB panels retain heat and absorb noise slightly worse than natural wood. The material has high environmental friendliness. The lack of wood in its combustion and absorption of moisture is eliminated by impregnation, additives and pressing.

When making house parts from panels with your own hands, you should take into account the specific location of the fibers and hardness. OSB cuts and drills worse than solid wood.

Frame houses are cheaper and quick to install

Frame house

Construction residential buildings from OSB boards is done according to the approved project. Blocks are made at the factory and labeled. A light foundation is made on site and then the frame of the house is mounted on it and sheathed with the resulting parts. The insulation is installed during the production of blocks. This method of construction has a number of advantages over standard brick buildings.

1. You can move into the house immediately after laying the roof and do the finishing, or simply varnish the inside walls.
2. Construction is done using the dry method and takes less than a month, including the creation of the foundation.
3. A frame house is 3–5 times lighter than a brick one. A light foundation at a shallow depth or a support-column foundation is made under it.
4. There is no need to use lifting mechanisms to erect walls and roofs.
5. The smooth surface of the panels is finished without complex plaster. Putty is sufficient for painting and wallpapering.
6. The material of OSB panels is used for insulation of brick and wooden house. Additionally, polystyrene foam or other extruded plastic is placed inside. The heat in the house is retained better than with brick walls 1 meter thick.
7. It's comfortable inside the house, the walls breathe.
8. They do not shrink.
9. There is no waste during installation; the blocks are made to size at the factory.
10. The cost of a frame house made of OSB is significantly lower than a brick one.

Frame houses also have their disadvantages. If you want to have a basement in your house, you need to make a strip foundation to its entire depth or dig and lay out the walls separately, at a distance from load-bearing structure. It is more difficult to hide the wiring with your own hands. Cannot be hung on OSB walls heavy equipment and cabinets.

Construction of frame houses

We build a house from OSB ourselves

If you want to build a house with your own hands from OSB, then you will need helpers. Optimal quantity for work 4 people. You can get by with a minimum number of workers - 2 builders. Then one must have experience in assembly frame houses. The second is to be able to understand it, present it, hold it.

1. Placed on the foundation waterproofing layer. There is a lower harness on it.
2. The racks and corners of the walls are attached, and a diagonal fastening is made to prevent the structure from “folding.”
3. The top trim is installed.
4. Floor and ceiling beams are laid.
5. The frames of the openings are installed.
6. The rafters are installed and sheathed.
7. The floor and ceiling are covered.
8. Sheathing is done with OSB panels.
9. Sealing extensions are installed at the corners and joints of the panels.

When building with your own hands, the walls outside and inside of a residential building are sheathed separately. Insulation is laid between the layers of OSB, wires and life support systems are laid.

Advice! Self-tapping screws do not screw into OSB well and become warped. It is advisable to drill a hole for them. The drill diameter should be smaller than the screw thread.

For thermal expansion, a gap of 3 mm is left between the panels and racks around the perimeter of the floor. There is a gap of 2 mm between the plates themselves along the entire sheathing. Wall panels do not reach the floor covering 10 - 12 mm. The finishing gap is closed with skirting boards.

The floor panels are laid on the beams across their location. There must be at least 3 crossbars under each OSB slab. Along the length, the ends of the sheets are connected on a beam. Both edges are secured with self-tapping screws. The pitch between the floor beams is 500 - 600 mm.

A house built from OSB panels can easily withstand outside temperatures from 40 degrees below zero to the same heat reading. The comfort of buildings is not inferior to brick buildings with insulation and wooden houses. The walls breathe, removing moisture out. The air inside remains fresh. Fungus and mold do not appear.

OSB sandwich panels

DIY house made from OSB sandwich panels

OSB sheets are also used to create sandwich panels. The space between two slabs of pressed wood chips is filled with expanded polystyrene. Such a house is assembled by a specialized team. Sheathing, installation and fastening are used similarly to the construction of buildings made of sandwich panels.

The frame and lining of the openings are made from boards 3 cm thick. The starting profile is a strip equal in width to the groove at the end of the panel. It is attached along the entire perimeter to the foundation with metal brackets. The panels are fastened together with timber. They are fixed to the posts with long screws.

The interior of buildings is inferior to houses made of OSB boards in aesthetics. Therefore, such technologies are rarely used for residential buildings.

To build quickly and inexpensively frame house, OSB – oriented particle board, fits all parameters. To build the frame, beams and beams are used, so the structure is light and does not require a massive and expensive foundation. Study the types of OSB boards, get acquainted with the features of the technology of building and finishing a house from improved wood.

Technical features of the material

Knowing the abbreviation is not enough to understand all the features of OSB panels. Therefore, it is necessary to study the advantages and disadvantages of this material, as well as its functional differences.
OSB is oriented strand board, that is, panels that are made from wood chips. You can also find the name in English – OSB.

What is OSB

These panels are somewhat similar to chipboard, but differ significantly in the installation method, as well as the type of chips used. So, in chipboard the chips are smaller, they are mixed in different directions and glued together chaotically. And in OSB panels, all the chips are directed in one direction, which is why they are called oriented.

Another feature of these panels is that each layer in them has its own direction. Usually there are 3-4 of these layers. As a rule, chips are placed in slabs as follows:

1. The first layer - make the direction of the fibers parallel to the panel structure.
2. The second layer is strictly perpendicular to the first.
3. The third layer is laid in the same direction as the first.
4. The fourth layer of chips is again perpendicular to the third layer of fibers.

Sometimes another option for placing layers inside the slab is allowed. So, you can make the direction of the chips in the outer layers parallel to the panel itself, and perpendicular in the two inner layers.

The chip size for the production of OSB panels is up to 15 cm in length. It is placed on a certain area and pressed under high pressure. To ensure that the chip fibers stick to each other, they are impregnated with waterproof synthetic resin.

According to reviews from many developers who used OSB panels in the construction of frame houses, thanks to this structure, the building frame becomes more heat-intensive, which saves money on heating.

Typically, oriented strand sandwich panels are used in the construction of buildings using Canadian technologies. This means that the wall in section represents three-layer construction.

Between two layers of OSB there is some kind of insulation. This is very comfortable, because this material is convenient to use, it has high performance characteristics, increased durability, ability to build quickly. But you need to take into account that OSB boards also have their disadvantages.

Advantages and disadvantages of OSB

When choosing, especially if we're talking about about building with your own hands, it is worth considering all its advantages and disadvantages. Essential advantage of OSB boards is that they are minimum thickness more durable and stable.

There are other positive qualities of this material:

• Minimum cost of building materials.
• Due to the fact that the slabs are lightweight, they can be installed without the use of heavy and expensive lifting equipment. Because of this, those who build a house on their own choose OSB panels.
• Minimum weight of slabs. If we compare wood slabs with brick, then their weight is 5 times less. Therefore, you can save on the foundation and make it less expensive and complicated, since even a very large house will be light.
• OSB frame houses can be built on almost all types of soil.
• Fire resistance. Although the slabs are made from natural wood, they don't burn like wood. Firstly, fire resistance is ensured through a special production technology. Secondly, the panels are treated with special substances.
• Moisture resistance. The house and OSB panels will not deteriorate even under constant exposure to moisture, since the material is treated with a special water-repellent coating.
• High thermal insulation properties. OSB maintains the temperature in the house well, even if there are strong temperature changes outside. Moreover, many sandwich panel manufacturers specially produce OSB boards with insulation inside, if the house will be used in particularly difficult weather conditions.
• Simple finishing. Due to the fact that the surface of OSB boards is almost perfectly flat and slightly rough, you can simply apply Decoration Materials without pre-treatment.

But even despite such an impressive list positive qualities This material has its drawbacks. But there are fewer of them than the advantages:

• Low sound insulation. Due to the fact that the slabs are very thin, they transmit sound very easily. Therefore, special soundproofing materials must be applied to them.
• Flammability. Although the materials are more fire resistant than ordinary tree, since they are impregnated with a special substance, there is still a minimal danger of maintaining a fire.
• The need to strictly follow all technology. Yes, you can build a frame house from OSB panels yourself. But to do this, you need to strictly follow the project and observe all dimensions perfectly. This is due to the fact that the building is assembled from many small elements, and if they do not meet the specified parameters, the constructor may not work out.

Classification of OSB panels

Exist different types OSB panels, which have their own narrow areas of application. All of them can be used at individual stages of building a frame house. Experienced builders agree that it is better to choose specific types panels for every situation, what to take universal material.

It is better to study the properties of various OSB boards before ordering the material in order to calculate required amount and areas of application in advance. Since there are only four options for slabs, choosing the right ones for each stage of building a house will not be difficult.

So, panels are distinguished by types:

1. OSB-1. These slabs minimal degree of strength and virtually no moisture resistance. They are purchased for interior work, since such material will collapse on the outside. The use of OSB-1 is especially important in the production of furniture and other small structures as a replacement for chipboard and plywood.
2. OSB-2. The slabs still have low strength characteristics, but they are already higher than those of the first type. Such panels are used not only for interior purposes, but also in the construction of light partitions and ceilings. It is not recommended to use slabs of this type in ground floors, basements, kitchens, bathrooms due to low moisture tolerance.
3. OSB-3. These panels are used most often because they are almost universal. They can apply both outside and inside in different parts of the house. They have fairly good resistance to moisture.
4. OSB-4. These are the most durable OSB boards that can be used for all types of construction work. The limited use is due to its high cost. This material is suitable for outdoor use. In addition, it is used in the construction of roofs and attics. The boards are resistant to moisture, so they can be used not only outside, but also in basements, plinths, and bathrooms.

The difference between all these types of panels is in the different adhesive base, as well as in different technologies gluing of wood chips and thickness of the layer. But there are other differences.

Selecting OSB depending on the type of coating

Both regular panels and those with laminated surface. The latter are purchased for the construction of multiple formwork. In addition, double-sided varnished boards can be purchased for decorative use.

OSB panels in frame houses are even used as a replacement floor coverings. To do this, special connecting elements are installed in them - grooves and end ridges.

Many homeowners buy OSB floor panels because it is a more budget-friendly and convenient option. According to builders, such floors have the following advantages:

• Due to the peculiarities of gluing wood chips and shavings, the material becomes more rigid, so it can better withstand any load.
• Due to the fact that all slabs are produced using the conveyor method, they have ideal exact dimensions, including thickness. They are more convenient to install, unlike many other materials.
• The panels have minimal weight, they are easy to transport and do not create problems during storage. Therefore, with their use, the efficiency of building a house increases.
• Excellent thermal insulation. Nobody likes cold floors, so they choose materials that can make them warmer. High thermal insulation is provided by wood chips.
• Available processing methods. OSB boards withstand cutting, drilling, and grinding well. Even if you hammer nails into the edge of the slab, it will not collapse.

OSB boards have advantages not only in the construction of a house, but also in its operation. They are as follows:

• Houses in which OSB boards are used as the main material for frames do not shrink because they are very light.
• In winter, these houses are very warm, so a minimum amount of money is spent on heating them.
• You can change the layout of the house, since the whole light material, and the removal of some elements will not violate the integrity of the entire structure.

But during operation, disadvantages may also appear. Some home owners are faced with rotting of the frame, others do not like the knots and presence of voids in some slabs. But these are extremely rare problems, and in most cases they are minor.

Of the more significant disadvantages of OSB boards, note the presence of phenol in the adhesive composition. This means that the environmental friendliness of the material may be slightly lower than expected. But in high-quality slabs the amount of harmful substances does not exceed the norm. In addition, you must choose correct type slabs, since waterproof panels contain more harmful substances, so they should not be used for interior decoration.

Painting OSB panels

You can paint OSB panels in the usual way, without using any special technologies. The main thing is to choose a paint that will match the wood. To decorative material adheres better to the surface and lasts longer, it is recommended to prime the panel before doing this.

In the interior the best option there will be application acrylic varnish. You can also choose water-based paints and stain. All these materials are recommended by builders.

Features of OSB boards in construction

So, the use of OSB panels in construction has its own characteristics compared to other materials:

1. It is a very versatile material that can be used in any building structure.
2. With these plates you can do it in a month or less.
3. The advantage of the plate is that it can be used as a construction part. It is enough to prepare the elements in advance required sizes, and then assemble them according to the project.
4. But at the same time, it is necessary to accurately prepare all materials and follow calculations in order for the designer to be assembled.
5. Thanks to its light weight, the building can be placed even on unstable soils. In addition, a regular foundation is required.
6. Since the OSB boards themselves are warm, the most inexpensive additional insulation will do. Moreover, you can purchase ready-made insulated panels. This is especially true for construction in regions with harsh climates.

When building a house from OSB, there is no need to be afraid of further shrinkage and distortions - when proper construction it won't happen.
