In addition to the now classic coniferous block house, more expensive versions of this popular finishing natural material are also presented on the domestic construction market. Larch-based block house belongs to the category of universal finishing materials and is used both for internal cladding of wall or ceiling surfaces, and for external facade decoration of any buildings and structures. The presence of visual similarity with a rounded log helps to create a unique interior solution, and gives the finished surface a special, natural decorative effect.
Larch house block
Larch fibers allow the material to be assigned among the hardest cladding products.
Compared to other coniferous species of wood, larch has:

In terms of durability and decorativeness, larch occupies a leading position, and a significant number of advantages has the main impact on the cost of finished products. Larch block house, today is an expensive finishing material.
The price of a larch house block is quite high when compared with products from other types of wood
A properly made block house is characterized by a flat type of inner surface, as well as a convex outer part. In addition to the indisputable aesthetic advantage, a very important advantage of the larch block house is the rather tight fit of the decorative elements to each other, which is carried out through an effective connection.
The thorn-groove system is represented by grooves on the lower ribs of the house block, and thorns or tongues on the upper part of the finishing elements.
This design feature allows for the most tight joining of the boards, and also contributes to the creation of a single, almost monolithic, decorative panel. Among other things, the finishing material made of solid wood is absolutely environmentally friendly.
Base the technology of manufacturing finishing panels of a larch block house is represented by a peculiar way of sawing logs and subsequent processing carried out at all production stages:
House cutter block
Production of block house panels
At the final stage of production, the finished product can be processed with special antiseptic compositions, after which it is packed into shrink films ..
. Only the material manufactured in accordance with the established standards has high performance and attractive appearance.

The reason for the popularity, high decorativeness and durability of larch finishing materials lies not only in the peculiarities of wood. The excellent characteristics of the finished product are due to the following technological features:
Block house, home decoration
A properly assembled structure improves thermal insulation performance and significantly improves soundproofing.
The treatment of the block house with varnish helps to limit the negative effects of moisture, prevents rotting and swelling. It is important to remember that the higher the cost of such a finishing material, the better its quality characteristics, and the longer this finish will last inside or outside the premises.
Finishing materials based on solid larch perfectly imitate classic log masonry, due to the rounded relief of block house panels. When choosing a material, it is very important to pay attention to the compliance of products with the established and regulated GOST standards.

Domestic producers of larch block house, depending on the quality of the original wood and processing technology, often mark their products as follows:
Block House "Extra"
Block house, grade A
Block house, grade А-В
Block house grade C
"Extra", "Prima" and "A" grade are always produced packed in a special cellophane shrink wrap. When choosing a finishing material, you also need to pay attention to the following features:
Sizes of panels
Resins contained in coniferous wood serve as a worthy protection against moisture and can prolong the life operation, therefore, such a material is in demand both for facade decoration and is widely used when it is necessary to carry out interior decoration in rooms with high humidity levels, including a bath.
The average service life of such a cladding, made according to the technology, is fifteen years, and materials additionally treated with paints and varnishes are able to maintain their quality and decorative characteristics even for more than twenty years.
It is not too difficult to independently calculate the amount of board required for finishing the surface. It is enough to use a construction tape, as well as a calculator and expert recommendations.
Step 1. We calculate the surface area by multiplying the wall height by its length.
To calculate the facing, you can use the simplest formulas
Step 2. We calculate the area of all windows and doors by multiplying the indicators of their length and height.
Step 3. We calculate the working area, subtracting the resulting area of windows and doors from the surface area;
Step 4. We calculate the total number of panels for surface cladding, focusing on the size of the block house and the number of products in one square meter.
It should be remembered that the area of all surfaces cannot be summed up, therefore, the calculation must be made for each wall strictly individually.
Calculation of the block house
For self-plating work surfaces with wooden panels must be purchased:
Also, in the process of installing wood sheathing, you will need a good hacksaw for wood or a jigsaw, allowing you to carry out high-quality cutting of the sheathing boards.
Tools for wall cladding with block house
Various fasteners can be purchased and used to mount wooden planking that simulates a log.
Block house clamps
Staples for a construction stapler
When installing using self-tapping screws, it is necessary to pre-make holes in the finishing panels. The size of the hole for fasteners should be several millimeters larger than the diameter of the self-tapping screw, which during installation should be sunk into the board and leveled with a plug or putty for wooden surfaces. Fastening is considered ideal in areas that are closed by a subsequent fragment.
Before finishing work, the panels should be removed from the packaging and kept for a couple of days at the temperature and humidity in which the installation is supposed to be carried out. Place the material on a flat and dry surface.
Unpack the packaging before installation
The preparatory work can also include preliminary leveling and cleaning of the surface from dirt, as well as removing antennas and other protruding elements. If necessary, it is necessary to fix insufficiently stable wall elements.
The main stages of self-assembly of a block house for exterior and interior decoration do not have significant differences, so you need to focus on the technology for performing such works.
Step 1. We cover the surface of the walls with a vapor barrier.
Brick surfaces need not be insulated; in all other cases, preference should be given to Izospan-V, Izospan-FB or Izospan-FS membrane films.
In baths and saunas, it is advisable to use a vapor barrier with a reflective layer - "Izospan-FD" or "Izospan-FX ". For interior decoration, you can use a two-layer polypropylene film material with an anti-condensation surface "Megaizol B".
Step 2. We mount the vertical bar crate.
It is recommended to process the timber with special refractory agents and antiseptic compounds. It is important to remember that the thickness of the timber should be equal to the thickness of the insulation layer.
Installing the battens
Battens for siding
Step 3. We install heat-insulating materials between the bars of the already made lathing ..
. For the arrangement of internal thermal insulation, mineral wool or fiberboard is used. Polyurethane foam and expanded polystyrene boards can be used as insulation for external walls.

The use of mineral wool for insulation
Step 4. We cover the heat-insulating layer with a windproof and moisture-proof film membrane, which will not allow moisture to penetrate the insulation.
Step 5 . Installation of the second layer of lathing. This method of finishing allows not only to fix the wooden panels with high quality, but also helps to provide a ventilation gap between the layer of insulation and the block house.
Step 6. Install the finishing elements one by one, with the tongue upwards, leaving the minimum ventilation between the panels a gap of a few millimeters.
Step 7. We fix the trim with fasteners, one of which is located next to the tongue , and the other is installed closer to the groove.

Fastening imitation timber
When sheathing external and internal surfaces with finishing materials, it is necessary to take into account some features of the block house:
Fasteners for block house
Joining boards using a docking bar
Protection and painting block of house
Antiseptics for outdoor use
When choosing a material, it is recommended to pay special attention to the end of the product. The denser the annual rings are, the higher the blockhouse quality is and the more durable the surface cladding will be.
