Stages of building a house made of laminated veneer lumber

1. Foundation

If there are no problems with groundwater, even suitable for construction strip foundation. GOOD WOOD uses pile-grillage in standard projects - such a base is guaranteed to withstand the weight wooden structure at high level groundwater. Before starting work, we carry out geodetic and geological research. As a result, there appear detailed diagram, information for calculating the foundation, design of the KZh (reinforced concrete structures).

2. Production

Each set is produced for specific project. The tree does not remain in the warehouse for more than 5 days, so there are no problems with fungus, mold, blue stains and other defects. GOOD WOOD uses a full production cycle - from manual sorting of boards, chamber drying to manufacturing 100% of parts for assembly. The production of timber is described in more detail on the page "".

3. Packaging and delivery

The packaging works like a membrane - it does not let moisture in, but does not prevent it from coming out. The timber will not deteriorate during storage construction site, even if you have to wait your turn in the rain. Each part is marked and placed in the assembly sequence so that there are no opened packs lying on the site.

4. Wall assembly

The builders remove the parts in order and place them in the right places. During the process, anti-shrinkage technologies must be observed: they install jacks, studs, sliding fasteners, leave technological gaps in window and doorways. More details about wall installation are described in the “” section.

5. Floors and roofing

Standard floors mounted according to wooden beams. Hidden communications (pipes, wiring) are placed inside. Several layers are used to increase sound insulation mineral wool, screed.

Mandatory technical supervision

The technical supervision engineer is present at all stages of construction:

• accepts hidden work foundation (reinforcement, piles), strength of the finished foundation;
• checks the wall kit after assembling the first and second floors;
• controls the gasket engineering communications;
• checks several stages of roof installation (rafter system, vapor barrier, insulation, waterproofing, ventilation gap, skylights, finishing coat).

In GOOD WOOD projects, the technical supervision engineer takes everything important stages, hidden work. This technology for constructing a wooden house from laminated veneer lumber helps to detect and eliminate defects in a timely manner, and to control stages that cannot be checked after completion of the work.

Mandatory Maintenance

Modern houses made of timber: serial and individual projects

Serial

The technology for building serial houses from laminated veneer lumber in GOOD WOOD has been worked out in detail: the architects have already made changes to the drawings and optimized the layout. Many serial projects can be viewed on demonstration sites or virtually.

There are no restrictions on the styles of individual projects: we design traditional Russian estates, modern and classic mansions, Finnish cottages, houses in high-tech, minimalist styles.

Compared to other wood building materials for the construction of house walls, laminated veneer lumber can rightfully be called the best. These products have many advantages that make houses made of this material strong, warm, durable and environmentally friendly. The technology for building a house from laminated veneer lumber is quite simple, so this construction method can be chosen for self-construction Houses. During the work you will not need construction equipment, which is additional benefit. You can also save on arranging the foundation, because it’s lightweight wall material will not heavily load the base.

Manufacturing Features

If you decide to make laminated veneer lumber yourself, the production technology requires specialized equipment. Without it, you won’t be able to make such material yourself.

The technology for manufacturing laminated wood material includes several stages:

1. Before production, the wood is carefully sorted. Only high-quality raw materials are selected. Wood is selected taking into account the variety, species, size and other important characteristics.
2. Next, the wood is sawed and dried. The material is sawn into boards of a certain size. The thinner the workpiece, the better it will dry. Drying of products is carried out in special chambers with modern equipment. The material is dried to the specified moisture content under continuous equipment monitoring.
3. Control and calibration. Next, the dried workpieces undergo careful control and calibration. This can be done either with special equipment or visually by workers. As a result, defective boards are removed.
4. Formation of lamellas. This stage consists of two stages. First of all, the dried material is sent to a machine, where areas with defects are cut out of it. After this, the board is cut into thin lamellas, which are spliced ​​in length.
5. Next, the workpieces are treated with antiseptic compounds to protect against rotting, fungus and mold, and are also impregnated with fire retardants to increase their fire resistance and resistance to environmental factors environment.
6. After this, the workpieces are lubricated with a special waterproof glue and are sent under pressure. As a result, under pressure, the adhesive penetrates into the pores of the wood and reliably glues the lamellas together. The total number of lamellas in one beam can be 2-5 and depends on the required thickness of the product. The final thickness of the timber can reach up to 250 mm.

Important: in the manufacturing process of timber, only high-quality, harmless glue is used that meets all safety standards. In addition, the adhesive used should not interfere with the natural “breathing” of the wood.

1. The last stage of timber production will be its profiling. Now the timber is cut to length up to required sizes, after which it is sent to a machine on which locking connections in the form of tenons and grooves are cut into the body of the product. These grooves and tenons are precisely adjusted in size and fit together without gaps or cold bridges. Thanks to this lock, when laying the timber, a sealed connection is obtained that does not require the use of tape inter-crown insulation.
2. To protect the product from mechanical damage or surface contamination, it is packaged before storage or delivery to the retail chain.

Typically, the glued timber is made from one type of wood. But in some cases, to increase its aesthetic appeal, lamellas of more expensive types of wood are used as two outer layers. Such products are more expensive than laminated veneer lumber made from one type of wood.

Advantages and disadvantages

Glued laminated timber, the manufacturing technology of which is described above, has its pros and cons. Among positive qualities this building material, thanks to which it is so popular, it is worth listing the following:

• High-quality dried and cut workpieces absorb various protective compounds. Thereby ready product and the entire building is reliably protected from negative impact weather factors, moisture, damage by microorganisms, insects, and are also less susceptible to fire.
• Thanks to a special technology for manufacturing and cutting locks, it is possible to achieve the most dense and airtight connection of individual wall elements. There are no gaps or cold bridges in the wall structure, so your home will always be warm, which will allow you to save on heating costs. You will receive additional savings during construction due to the fact that you will not need inter-crown insulation. In addition, a tight and even connection of the elements, as well as the absence of insulation sticking out of the cracks, will have a beneficial effect on appearance Houses.
• The timber manufacturing technology helps preserve all the positive qualities of wood, thanks to which a favorable microclimate is formed in the house, humidity and temperature in the room are regulated.
• Thanks to chamber drying technology, well-dried wood practically does not shrink, so after building the frame of the house, there is no need to take a long pause for shrinkage before starting finishing work and moving into the house.

Attention: shrinkage of a glued house wood material according to technological standards should not exceed 1.5%.

• Beautiful Smooth surface timber allows you to do without any finishing of the house, which will allow you to save a lot.
• The load-bearing capacity of laminated veneer lumber is much higher than that of solid wood products. This makes it much better than ordinary profiled timber, rounded and untreated logs.
• Dimensional stability. This material is not afraid of changes in humidity and temperature, prolonged static loads, freezing and thawing. It does not respond to all these factors by deformation, shrinkage, cracking and change geometric shape and sizes.
• There are no through cracks on the laminated material, therefore the thermal insulation characteristics of such timber are higher than those of other solid wood products.
• Since during production it is possible to prepare laminated veneer lumber, the dimensions of which will be precisely adjusted to the future construction, during the assembly process waste will be minimal or even equal to zero. This helps reduce estimated cost, speeds up the construction process and allows you to save on labor costs if the house is built by a hired team.

Among the disadvantages of glued products, it is worth mentioning the following points:

• The weight of laminated veneer lumber is slightly higher than that of ordinary products made of wood. However, the increase specific gravity not critical, so this will in no way affect the production of the foundation.
• You should only buy glued elements from a reliable, trusted manufacturer, since you cannot control the manufacturing process. Unscrupulous manufacturers take advantage of this and use low-quality glue or defective wood; they may also work on outdated equipment, which will affect the quality of the product.

Timber laying technology

The technology of construction from laminated veneer lumber is no different from the installation of any wooden house. You can make a lightweight foundation by choosing a shallow strip foundation, a pile-screw or columnar structure. After this it is necessary to carry out horizontal waterproofing grounds. To do this, two layers of roofing material are laid on bitumen mastic.

After this, adhere to the following installation sequence:

1. A larch backing board is laid on the foundation. It must be subjected to antiseptic treatment. The board is leveled. Thanks to this board, it will be possible to protect the expensive timber of the first crown from the destructive effects of moisture and rot.
2. Next, we proceed to laying the first casing crown. First, two beams are laid on opposite walls, and after that the elements on the walls adjacent to them are mounted in grooves. To make a crown molding, you should choose the most durable ones, quality products large section.
3. Corner connections of elements can be made different ways- “in the paw”, “in the bowl”, “in half the tree”, that is, with the remainder or not. The warmest connection is obtained when laying corners according to the Canadian bowl principle. As a result, all elements are reliably connected into one structure without cold bridges or blowing.
4. The first beam is attached to the foundation using anchor bolts, which are inserted into pre-drilled holes.
5. The following elements are being installed. Lock connections all rows are joined according to the “groove-tenon” principle. Insulation of places is mandatory corner connection elements.
6. If there are no grooves in the thickets of the timber for insulation, then it can be laid directly on the bowl of the underlying element at the corner joint.
7. After laying each subsequent row of timber, they are pressed. The width of the inter-crown gap should be no more than 1 mm. It will close after the building settles.
8. Every three crowns, additional fixation is made using long dowels wooden elements. They will give the structure additional stability and protect the logs from twisting.
9. Also, the crowns are additionally tightened with pins to prevent the formation of gaps between the crowns after the building shrinks.
10. The process of installing a roof is the same as when building a house from other wood materials.

Glued laminated timber is a type of timber that consists of several pre-dried lamella boards that are glued together with a special compound. A house made of such material shrinks less than a house made of logs or ordinary timber; the material itself almost does not change shape during use. Such qualities make construction from laminated veneer lumber increasingly popular, despite its relatively high cost. How to build a house from laminated timber?

The first stage is project development

It is better to entrust this work to professionals. They will take into account all the customer’s wishes and the characteristics of the material and develop a house that will be comfortable and safe. Ready-made projects can also be found on the Internet; as a rule, they reflect only the main points: the size of the building, the location of the rooms, internal partitions, stairs, windows, doors. But it should be remembered that a house is not only walls and a roof, but also communications, which also need to be laid in accordance with certain requirements.

Technology of building a house from laminated veneer lumber

When the project is developed, the house is assembled according to the diagram, like a constructor. However, the construction of walls from this material has its own characteristics.

• It is important to check the evenness of all joints and the geometry of walls and corners.
• Jute insulation is used for seams.

Glued laminated timber can have a German or Finnish profile, which differs in the number of grooves and ridges. Thanks to the tongue-and-groove connection, laminated veneer lumber, like profiled timber, is better protected from moisture between the crowns.

Technology for building a house from laminated veneer lumber includes a strip shallow reinforced foundation. The depth of the foundation, as a rule, is no more than 70 cm, while it should rise above the ground by at least 50 cm. If the house is large, then additional brick columns are laid under the floor joists.

The floor joists are attached to the first crown of the timber. After laying them, walls are erected, and then an interfloor or attic floor.

Technology for laying laminated veneer lumber for wooden houses even simpler than the technology of laying profiled or solid timber thanks to more precise geometry.

In the corners, laminated veneer lumber can be joined in several ways. The easiest way is if you bought a timber that has already been marked and sawn “for the project”, then cups for joining have already been cut into it, all that remains is to simply assemble the house according to the instructions. If an unmarked beam is purchased, it is connected in the same way as other types. Connections using metal corners are not recommended. The following types of connections can be used:

• on dowels,
• root thorn,
• end to end
• half a tree,
• in the paw
• frying pan or semi-frying pan,
• dovetail at 45 degrees.

The floor consists of rough flooring, which is attached to the joists using metal corner, and insulation is laid on it between the lags. A finishing floor is made on top.

They do it for the roof rafter system. You can also use laminated veneer lumber for it, usually smaller in size than for walls. The sheathing is nailed to the rafters and arranged roofing pie with waterproofing, insulation and vapor barrier.

Insulation

Is it necessary to insulate a house made of laminated veneer lumber? Exist different opinions on this score, however, if the house is intended for year-round use, experts advise insulating it from the outside. If the house is used periodically and is not heated every winter, then internal sealing is necessary. The benefit of insulation also lies in the fact that in an insulated house, the right conditions for wood, it does not rot or dry out.

Insulation of a house made of laminated veneer lumber includes the following measures:

• sealing all seams in the house, eliminating holes, cracks,
• insulation of the attic, if any,
• sealing all openings near doors and windows,
• sealing of floors,
• sealing and thermal insulation of the building with insulation from the outside,
• floor insulation.

How to insulate a house and what insulation to choose? In the choice of material main role The thickness of the walls and climatic conditions play a role. Typically used as insulation:

• felt,
• cork,
• Styrofoam,
• mineral wool.

If you decide to make do with insulation from the inside, then optimal thickness insulation - 3 cm. This thickness does not significantly reduce the area, but it retains heat quite effectively and works as sound insulation.

Before laying insulation, the walls of the house are treated with an antiseptic. To insulate the outside of the house, a frame made of bars is attached to the walls of the house; the distance between the frame elements should be slightly less than the width of the insulation sheet so that the heat-insulating material fits tightly between the two bars. After this, the insulation is laid from bottom to top, and attached to the top windproof membrane. The final stage is decorative finishing.

Window installation

Important! Despite the fact that laminated veneer lumber shrinks less than a log or profiled beam, it still occurs, so time must pass between the construction of walls and the installation of windows.

Both wooden and plastic windows are installed in houses made of laminated timber. Installation plastic windows in a house made of laminated timber it is done as follows:

• The first stage is window marking. The height of the window sill is made within the range of 90-130 cm. A smaller height is unsafe, and a larger height is inconvenient. Next, the dimensions of the window structure itself are marked on the wall, from which the dimensions of the casing are set aside - 2.5-5 cm (board thickness). The thickness of the window carriage into which the frame is inserted is also taken into account. In addition, add 1.5 cm for polyurethane foam.
• Further cut a hole for the window. They do it circular saw. After cutting, you need to cut off all split areas. Then the hole is checked for level and its edges are ground.
• After this the tree treated with antiseptics.
• Constructing a casing box. She will protect window design from shrinkage of the house, which will continue throughout the entire period of operation, although less than at first. There are two options here: either the groove is cut out at the ends of the beam, and a tenon is cut into the casing frame, or vice versa. The casing is made from planed and sanded boards.

Attention! When installing a window frame, it is advisable not to use fasteners, especially self-tapping screws or nails. The casing frame must move in the opening so that it can soften the load on the glass unit from shrinkage of the house.

After this, the window is installed. If the block is a sash, then the sash is removed and the frame is installed first, and then the sash is hung. If the window is not casement, then assistance will be required, since the weight of the window is quite large.

• The frame is inserted into the opening, leveled and grabbed in several places.
• Next, the glass unit is finally leveled and screwed simultaneously on the right and left.
• The installation of windows in a laminated timber house is completed by foaming the gaps.

Advice! If you do not have experience in such work, then it is better to turn to specialists. Of course, you will have to pay, but you will receive competent work with a guarantee. If you are confident in your abilities, but have not yet installed windows yourself, you need to consult a specialist.

Glued laminated timber - modern material, and building a house from it is for many reasons easier than from other lumber. However, it also has its own characteristics. It is important to observe geometry during construction, and if the house is assembled according to finished project, do not deviate from the instructions.

LLC "GK Priozersky Timber Plant" has been operating in the timber market since 1999 and is the largest in North-West region timber enterprise full cycle for wood processing.

The main activity of our plant is the production of houses from profiled laminated timber and the sale of related lumber.

You can build a house from laminated veneer lumber in a few months. You can discuss the cost and buy a house kit throughout the year. Sales are carried out at the company's head office at the address: St. Petersburg, emb. Martynova, house 6.

Every season market suburban construction is replenished with new housing construction technologies. Over the past few years, house projects made from laminated veneer lumber have become very popular among buyers. This is due to the many positive qualities they possess.

Advantages of timber houses

1. Environmentally friendly construction. The glue used to join wood is safe for humans and the environment. It consists of natural composites. Additionally, the glue acts as an antiseptic, preventing the appearance of pests in the material.

2. Wooden houses constructed from laminated veneer lumber quickly. An experienced work team assembles a building on a finished foundation in 1 month. Thus, the entire construction of a house from the construction of the foundation to completion can take only 3 months.

3. Glued laminated timber is characterized by low thermal conductivity. This helps reduce the cost of heating the premises from it to winter time. During the construction of a house, only insulation of floors and ceilings is required.

4. Houses made of laminated veneer lumber, reviews of which are mostly positive from owners, are strong and durable. This is due to the peculiarities of the material production technology.

5. Wooden buildings made of timber have stable geometric dimensions, that is, the material does not twist, bend or shrink.

Disadvantages of timber houses

1. For wooden house special care is required, only this ensures the preservation of the pleasant color of the external walls. Every year they need to be coated with special compounds that slow down the rate of aging of the building.

2. Various manufacturers may use special fireproofing impregnations that are not safe for humans. Before purchasing the material, it is necessary to clarify exactly what compositions were used.

3. The construction of houses made of laminated veneer lumber is sometimes delayed due to the need for additional sanding of the walls. It is a consequence of the fact that during transportation the material gets dirty, and it is impossible to remove dirt from it by rubbing.

Glued laminated timber manufacturing technology

The technology for producing laminated veneer lumber was first tested more than thirty years ago. Now the material is very popular.

The raw material for timber is logs. Passing through special equipment, they are dissolved into boards. They are dried at certain temperature and humidity levels in the room. After this, the material is checked for defects.

Boards suitable for use are treated with antiseptics and fire retardants, then planed. Only if all these operations have been completed can you begin to directly form a beam of 2-5 layers. The boards are connected to each other under the influence of a press. A special water-repellent glue is used as an adhesive, which does not interfere with the wood’s “breathing”.

The boards are laid under the press in a certain way. Fibers of different layers are directed in opposite directions. This significantly increases the strength of the manufactured product. This structure protects the tree from changing size under the influence of environmental conditions. Due to its high strength, laminated wood can be used as floor beams and rafters in a house under construction.

Reviews from owners about houses made of laminated veneer lumber

On Russian market houses made of laminated veneer lumber, reviews of the owners of which will be discussed below, have been known for more than ten years. During this time, building construction technologies have improved slightly. Owners of houses built quite a long time ago can objectively speak about all the actual advantages and disadvantages of the technology under consideration for the production of timber and the construction of residential buildings from it.

Reviews about the actual construction time of houses

Manufacturers and construction companies they claim that houses made of profiled laminated veneer lumber can be erected in 1 month. This is true. A box of standard buildings, the designs of which have already been repeatedly applied in practice, are erected very quickly. But then comes the stage of interior finishing work, which can last for months or even a year.

When choosing a project, customers need to pay attention to various nuances. For example, the locations of holes in the timber for installing lamps and running pipes. All these small additions will further affect the speed of communications and finishing work.

It is worth keeping in mind that standard interiors of houses made of laminated veneer lumber are created faster than extraordinary ones. As a rule, to carry out the latter, the owners of the future home hire a designer who takes responsibility for the deadlines for completing the order.

We can conclude that the construction of houses made of laminated veneer lumber takes 3-4 months only if it uses standard solutions for finishing work and installation of plumbing. In all other cases, the terms increase several times.

Feedback from owners about maintaining the dimensions of laminated veneer lumber declared by the manufacturer

Wood tends to dry out under the influence of environmental factors. Glued laminated timber, according to manufacturers, is not subject to this, which allows you to proceed finishing works immediately after assembling the box at home.

In reality, the material may dry out a little and shrink. The formation of small cracks is also possible. This is especially noticeable at the ends of the house.

Such phenomena must be taken into account when installing frames for windows and doors. Glued laminated timber does not require mandatory interior finishing; the special texture of its walls itself creates a unique atmosphere in the house. Some owners specifically choose house designs made from laminated veneer lumber in order to get a semblance of a village hut inside.

In winter, the street is relatively dry and the outer walls decrease in size by several centimeters. Internal logs at the same time, they are in a more humid environment, since people live there who cook food, wash clothes and take showers. The difference in humidity outside and inside leads to the fact that in winter some changes may occur in the frame of the house, manifested in the appearance of a distance between the beams. In spring this phenomenon will not be so noticeable. This does not affect the safety of being in the building.

Thus, small changes in geometric dimensions are characteristic of laminated veneer lumber. This should not be neglected during finishing work.
