The appearance of natural wood has remained popular at all times. Therefore, when decorating the facade of a building, many tend to use this particular material. However, this implies a complex construction technology with the need to pay for the services of expensive specialists. The array itself is not cheap, which is not available to everyone. An alternative solution for such a situation would be an imitation of a larch bar.
This lumber allows you to create the external impression that the facade of the house is built of natural wood. At the same time, it costs several times cheaper than a real bar, allows you to build quickly and even with your own hands.
This is an environmentally friendly material, which is a larch wood slats. Along their lateral perimeter, special cuts were made with a milling machine, which function as locks. Such protrusions allow you to tightly dock the board with each other, while creating the appearance of a holistic structure.
The material is used as the basis for cladding facades and even interior decoration.
Various softwoods can be used as raw materials for making imitation timber. Most often it is larch itself, sometimes pine is used. The thickness of the board can be from 20 to 40 mm. The width of the planks varies from from 135 to 200 mm.
Most often, it is better to choose a board 20x146x6000 mm for cladding one and two-storey buildings. It is quite stiff and much cheaper than thicker material.
For the manufacture of false beam, wood with a residual moisture content of 14% is used , due to which, during storage and installation of finished material, its warping is excluded. Finished imitation larch timber can have different shades from yellow to brown. The material is environmentally friendly and non-toxic, but in case of individual intolerance, it can cause allergies and hives.
This is observed only in people with a genetic predisposition to intolerance to conifers, which occurs every 10 thousand cases.
In general, the scope of use of imitation of a bar is very extensive. It is used for construction and upgrading:
Often, the use of imitation of larch timber is chosen to restore the facades of old buildings, but most often the material is used for facing new buildings. It is great for country houses, cottages, hotels and other low-rise buildings.
Fastening of the imitation larch timber is carried out to the frame, which is pre-mounted on the facade of the building.Thanks to this technology, it is possible to create the external impression of evenness of the walls, even if the base has serious curvatures. In practice, imitation can be used for the restoration of old buildings by creating ventilated facades that hide defects. The beam can be used for facing buildings from the following materials:
Application of this material is an opportunity for significant savings, both in terms of estimates and construction time.
Thanks to the fastening to the frame, it does not matter what the walls are made of. They can be folded from large gas blocks, panel slabs and other budget materials that allow for construction in a short time. After that, the surface of the facades is covered with an imitation of larch timber.
Attention! The applied installation technology allows for preliminary insulation of buildings with any heat-insulating materials, including mineral wool and polyurethane foam.
The possibility of insulation allows you to save on the materials themselves for laying walls, while fully compensating for their high thermal conductivity using inexpensive insulation.
At the same time, during construction, there is no need to comply with the aesthetics of masonry, and the need for external plastering work is also eliminated.
Larch is a tree from the pine family. Its wood is often used for facade cladding. This is due to the high aesthetic appeal of the material, richness of texture and depth of color.
Operational properties of larch.
|Resistance to fungal formations and lesions insects||high|
|Resistance to weathering||high|
|Service life||10-15 years|
|Resin release when heated||80-90 ° С|
|Moisture level of dry material||up to 14-15%|
|Densities g / cm3||0.66|
Technical the parameters of wood do not always allow the use of larch when arranging a bath and a sauna. This is due to the fact that when the temperature rises to 80 ° C and above, resin is released , which is accompanied by a corresponding rosin smell. Many people do not like this, so before choosing a false beam for a steam room, it is better to weigh the pros and cons.
It is believed that such wood releases medicinal phytoncides into the air, which improve the indoor microclimate.
The material has a natural resistance to wood pests and putrefactive bacteria. This ensures its long service life even without specialized impregnations. Due to its moisture-repellent properties, the painted imitation larch bar can be washed to remove dirt deposits.
The closest competitor of this material is imitation oak, but although larch is less hard, it is more resistant to wear and tear.
Even while on the facade of a building, cracks are very rare.
The average specific gravity of larch is calculated by weighing wood with a moisture level of 12%. When buying lumber for finishing, the degree of moisture content in it can be 14-15%, which is the norm. Thus, the actual weight of the board will be slightly higher than the tabular data.
Weight of a larch board 6 m long.
|Section, mm||Weight, kg|
|150х25|| 15. |
|200х32||26. 5| Lining, imitation of a bar, block-house
The process of fastening the imitation timber larch to the facade, walls or ceiling does not differ from the technology of working with other similar materials. If you wish, you can do everything yourself without involving paid specialists. This requires a minimal set of tools. Ideally, use a screwdriver and screws for fastening, but nails and a hammer are acceptable.
To complete the work, you will need a horizontal level, a plumb line, a construction stapler and a set of concrete drills to secure the frame. A miter saw, circular saw, hand jigsaw or hacksaw can be used to cut the material to the required length.
Attention! Recommended after purchasing a simulation larch timber to fold the material for 7-10 days for its acclimatization within the installation area. As a result of storage, the board will acquire the required level of humidity, which will exclude its deformation after rigid fixing.
Direct editing is carried out in the following order:
Waterproofing the walls with a membrane material and a construction stapler. The film is laid with an overlap of approximately 40 cm.
Step 2. Carrying out markings to fix the guides.
Securing the frame. For its manufacture, metal profiles can be used, as well as a wooden block with a cross section of at least 30 mm. The crossbeams are fixed vertically and strictly parallel. The distance between the beams is 60-70 cm, which depends on the rigidity of the timber imitation.
Laying the insulation. It can be used as mineral wool, as well as any other material. It is fixed in a spacer between the bars.
Step 5. Insulation waterproofing.
Step 6. Direct the panels are fastened from the bottom up. They are subject to horizontal orientation. You need to start at a distance of 15 cm from the bottom of the building. When joining the grooves, it is necessary to maintain a gap between the panels 2 mm.
It is needed to prevent material warping during off-season fluctuations in humidity.
Step 7. Painting the facade specialized means.
Direct fastening of the imitation of a bar to the frame can be carried out with self-tapping screws, nails or special clamps. The use of the latter eliminates the need for direct drilling of the simulation itself.
Since larch has a high density, it is better to make a through hole with a thin drill before screwing a self-tapping screw into it.
If only one screwdriver is available, this slows down the installation, therefore the use of clamps is preferred. Since they only attach to the frame, which is usually made of pine, no pre-drilling is required. The foot of such an attachment presses the imitation of a bar, without creating external damage on its surface.
If desired, it is allowed to lay an imitation of a bar with an overlap, in this case, overlapping boards should be not more than 30 mm.
The vertical arrangement of the false beam is allowed only if it is under a canopy, which prevents moisture from entering it.
The specificity of this material does not allow it to create attractive board joints at the corners. In this regard, overhead wooden corners are used to decorate the latter. They can be purchased ready-made or made using the same imitation. To do this, you need to cut off the locking part of the board using a circular saw.
Two imitations of a bar are installed vertically at an angle, one for each wall. Usually, later, when carrying out painting work, the vertical parts of the facade are painted in a different shade, but not always.
Since this is natural sawn timber, it is natural that it is divided into grades depending on the quality. This is primarily due to the appearance of the board. The differences between the varieties are due to the coating of the surface with a different number of natural imperfections, such as knots or tar pockets.
Their presence reduces the attractiveness of the appearance, although in certain styles of interior and exterior decoration, the use of such materials is more preferable. As for the direct mechanical properties of different grades, they are almost the same.
There are 4 main varieties of timber imitation in total
There are also mixed types AB and BC, when surface sorting is possible. It is important to understand that for the manufacture of imitation of larch timber of different varieties, manufacturers use identical technology and use one batch of timber.
The material is dried in common drying chambers and processed by the same machines. The only real difference is that the sawing resulted in a knot or other natural defect on the board.
The boards obtained after cutting can be hand-packed. Each grade has its own deviation rates, according to which the total batch of sawn timber is divided into four groups.
Differences between the varieties of imitation of larch timber.
|Extra||Highest grade with perfect geometry. The board is free from knots. The wood has a natural light shade without stains and mechanical defects.|
|Class A|| The boards have a smooth surface with a knot index from 1 to 3.
|Class B|| A slight violation of the board geometry is allowed, but does not affect the quality of the installation. There may be sanding gaps on the surface. The number of knots on the front part does not exceed 3 pieces. Mechanical damage and resin pockets up to 2 pieces are allowed. The depth of defects in the form of chips and cracks to a depth of 0.
|Class C||The lowest grade material with mechanical damage. On the board there are knots that have fallen out, as well as irregularities in the gluing of the timber. Deep cracks, chips and resin pockets can be found on the material.|
Imitation of the Extra class larch timber is an absolutely ideal material without any defects.
However, the absence of damage gives the impression of artificiality. At a cursory glance, it may seem that not an expensive imitation of a bar is used on the facade, but a cheaper metal siding.
Despite the fact that the difference between the imitation of different varieties is fundamentally different, there are lumber that is generally not allowed to be sold for finishing. The buyer has the right to demand from the seller to replace such a board if the following defects are detected in it:
Impregnation for wood
Imitation of larch timber is a beautiful material, the advantages of which must be emphasized correctly.
For this reason, naturally, no one uses opaque colorants. Ideally, use special impregnations consisting of natural ingredients. There are many German brands of paint and varnish products on the market that fit perfectly. When choosing materials for painting imitation of larch timber, you need to pay attention to their composition. It is desirable that it includes:
Such compositions are also offered by domestic manufacturers, the range of which is an order of magnitude cheaper. The use of such materials for painting allows you to extend the life of the larch and not harm its surface. Impregnations protect wood from wind, ultraviolet radiation and temperature changes. They also enhance the properties of larch.
Pay attention! Impregnations are produced separately for indoor and outdoor use.
In the event that it is necessary to paint the imitation inside the building, you need to select the appropriate paint. It has less protective properties, but lacks the bright smell of oils.
Painting imitation larch timber with impregnating compounds should be carried out with sufficient consumption specified in the instructions. The fact is that the substances must penetrate the board, creating an impenetrable protection on its surface against adverse effects. For this reason, it is ideal to do the work by hand with a brush.
Using a spray gun will only create a thin layer.With regard to the use of the roller, its plane is not able to penetrate into the recesses of the imitation grooves, which is unacceptable.
The pricing policy of this material is fully consistent with those generally accepted in the sawn timber market. The cost is influenced by:
Larch is different: Siberian, Kuril and European.
They differ in hardness and shade. Lumber of the same geometry and type in all parameters may have different prices, depending on which tree they were cut from.
