Design characteristics

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.

The process of making quality material

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:

  • cutting the outer parts from a log to obtain four blanks;
  • drying the blanks inside special drying chambers up to wood moisture indicators of 10-12%, which makes it possible to obtain durable and crack-resistant products;
  • cutting on the side surfaces of the dried workpiece of the fastening system in the form of a groove and a thorn;
  • drank along the entire length of the inner side of the longitudinal notched grooves, which will allow ventilation under the cladding, and also serve as an excellent protection against moisture and condensation;
  • alignment of the product in width according to established standards;
  • giving to the front side rounded blanks followed by sanding until an optimally smooth surface is obtained.

Technological features

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:

  • careful selection of the initial raw materials and components for manufacturing, as well as correct subsequent processing;
  • the processing process includes mandatory grinding and final cosmetic manipulations , including the impregnation of wood with protective agents;
  • production of finishing elements with special grooves, allowing to connect all the fragments together without the use of complex additional devices.

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.

Standards of larch block house

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.

How to determine the grade

Domestic producers of larch block house, depending on the quality of the original wood and processing technology, often mark their products as follows:

  • "Extra" - there are no such mechanical damages , like knots and defects of wood on the front side, which is due to very careful selection and manual sorting of finished products;

    Larch house block - do-it-yourself assortment and installation rules

    Block House "Extra"

  • "Classic" - it is allowed to have a well-cut outersurfaces without mechanical damage, through cracks, chips, areas from fallen knots and blue, but a small number of knots is possible;
  • "Economy" - the standards allow minor surface damage of a mechanical nature in the form of small cracks, chips and blue, and there may also be knots that have fallen out;
  • grade "A" - the presence of minor defects and errors in the form of one knot, a pair of resin pockets and a pair of blind cracks for every one and a half meters of length is allowed on the finished product;

  • wide panels are imitation of logs D 14-19 cm, which allows external finishing of buildings. The most popular block house is 32x120 mm and 42x160 mm;
  • narrow panels imitate Euro lining and are usually used for interior decoration in premises. The most in demand is a wooden block house with dimensions of 20x80 mm and 20x100 mm.

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.

Self-calculation of the amount

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.

Required tools

For self-plating work surfaces with wooden panels must be purchased:

  • construction level;
  • construction stapler and brackets for fastening film materials;
  • dowels for fixing insulation plates;
  • compounds for wood impregnation;
  • hammer and screwdriver;
  • construction tape;
  • electric drill.

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.

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.

Preparatory work

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.

Finishing technology

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.
