Often houses that look like they were built from a bar are not. This look is given to them by the imitation of natural timber, which is now becoming a very popular finishing material. It is also used in the creation of original interiors. Let’s talk about the false beam in more detail.
Wooden house building is in trend now. Therefore, often the owners of stone, brick, panel, aerated concrete houses decide to decorate the facade with a material that imitates natural timber. Previously, siding was used for this purpose, including metal or fiber cement, which tried to copy the structure of natural wood. However, up close, the fake was easy to identify..
Nowadays, such siding is increasingly being replaced by an imitation of profiled, glued beams, which, even upon closer inspection, is difficult to distinguish from the original.
Imitation of a bar is actually made from natural wood. That is why it is superior to metal siding in terms of decorativeness, similarity to a real profiled bar. It turns out that it is not necessary to imitate the structure of a tree, it is present in reality, only a similarity with a specific material is given – a bar.
An imitation of a bar is made as follows: a facing board is cut out of a tree, which, after the initial sawing, is calibrated, undergoes multi-stage drying in special chambers, then profiled and sorted. Profiling implies the creation of side chamfers beveled at an angle of 40 °, the formation of thermal paths on the back side and a tongue-and-groove system for convenient and durable installation. The moisture content of such imitation of a bar is less than 12%.
Most often, timber imitation is created from coniferous wood planks. But there are also luxury options. If the pine cladding will cost about 300 rubles per square meter, then the imitation of the larch timber will cost the owners already 1400 rubles per square meter..
The standard dimensions of the raised beam are:
- Thickness from 14 to 40 mm;
- Width from 110 to 190 mm;
- Length from 2 to 6 m.
Most of all, a board with a thickness of 22-30 mm and a width of 150-180 mm looks like a timber. It is she who is most often used on the facade. The length is selected based on the length of the trim section so that the joints are as small as possible.
What is the difference between imitation of a bar and a lining or block house? False timber, in contrast to the lining, is more massive, wider and thicker, the front side is noticeably better processed, and it is also stronger and more reliable. The block house, on the other hand, does not imitate a timber, but a rounded log, so these are similar materials, but with a different appearance. In addition, it is more difficult to assemble a block house..
The entire false beam is divided into classes:
- “Extra”. The highest grade, which has not yet learned to make in our country. Perfect finish, perfect geometry, perfect surface without knots and even microscopic cracks. It is very expensive and therefore unpopular;
- “AND”. It is produced in Russia, therefore, it is much more affordable and popular. No cracks or damage, but knots are acceptable – maximum two per running meter. There may also be resinous areas, but only on the back. The geometry of the board is excellent;
- “AB”. Mixed class with more errors. True, resin pockets, traces of pests are allowed only on the back. There can be three knots per linear meter;
- “IN”. Here, the roughness of the front side is already allowed, in places, due to errors in grinding. There are also no more than three knots on the front side, but they can also be accompanied by resinous pockets. Cracks up to 0.5 mm are allowed;
- “Sun”. There are already a lot of knots, including fallen ones, and traces of pests are not uncommon, cracks can be deeper than 0.5 mm, mechanical damage, defects in the thorn-groove system are permissible;
- “FROM”. The proportion of defects can reach 70% of the entire surface. The material will have to be additionally sanded, to close up the traces of fallen knots, that is, to prepare for use. But, of course, the price is the lowest.
The advantages of a raised beam include:
- Good sound insulation and low thermal conductivity;
- Creation of a favorable microclimate in the house;
- Ability to evaporate and accumulate excess moisture;
- Stable dimensions;
- Ease of installation;
- No shrinkage;
- Easy to care for;
- Resistant to moisture, decay and mold;
- Lower price than natural timber;
- Beautiful, presentable appearance.
On the facade of the house, an imitation of a bar is attached to the crate. “Pie” turns out to be multilayer: vapor barrier, battens, thermal insulation, hydro and wind protection, counter-lattice, false timber.
The imitation of the timber is attached to the crate with wood screws, nails of a suitable size or clamps.
In the interior, the raised beam, due to its qualities, can be used even in the decoration of toilets and bathrooms. Often insulated loggias and balconies are sheathed with this material, one wall in the living room or bedroom is distinguished. You can even create a completely wooden interior, but such a step will reduce the usable area of the room by about 5%..
When installing a false timber inside the house, clamps are often used as the most inconspicuous type of fastener. Lathing is also needed, as well as a vapor barrier, but you can do without insulation. Imitation timber can be painted or coated with wax.
False timber can be laid both vertically and horizontally. Vertical installation will visually raise the ceiling or increase the height of the house. The corners are joined using a 45 degree notch, and they also use platbands or special overlays.
There are few disadvantages to imitation of a bar, among them the main one is the need for special processing. However, this requirement applies to all wood materials. In addition, the raised beam burns like the rest of the tree..
