A variety of facing materials will turn a head to any buyer. To make the right choice, you need to know what material will serve the faithful service and will not fail in any weather. The most optimal solution financially for wall cladding in various construction and household structures is the material called lining or “block house”.
The house, lined with material "block house", looks restrained and concise, but it is very dignified and stylish, so the "block house" is widely used not only in the exterior, but also in creating interior solutions.
Once upon a time, the question of what material the “block house” is made of did not even arise. Now presented a variety of modern materials for decoration for every taste, which represent a wide scope for creativity. Consumer properties, sizes, profiles, colors of the “block house” are unlimited, which makes it absolutely “flexible” in the implementation of any exterior solutions of the consumer, providing an excellent visual combination in various styles.
“Block house” is a panel that imitates timber, which can be made of various materials, such as vinyl, metal, MDF, natural wood and others.
Wooden siding “block house” imitate a log, but it is a board with a planed surface with a width of 80 to 150 mm and a thickness of 8 to 20 mm, characterized by the presence of grooves and a comb. The most common samples are made of pine, larch, oak, linden, alder and others. Wooden “block house” is divided into the following types depending on the purpose:
- for interior decoration (approximate overall dimensions of the panel 22x99x2100 mm or 22x99x3000 mm);
- universal (36x142x3000 mm or 36x142x 6000 mm);
- for exterior decoration (36x1930x6000 mm).
The metal “block house” also imitates timber, but has a number of advantages in terms of light resistance, fire resistance, is resistant to temperature extremes and unpretentious in maintenance. The main area of its application is facade cladding. The approximate overall dimensions of the panel are 22x360x600 mm.
PVC “block house” is the most budgetary of all of the above, but this does not prevent it from having a decent list of positive properties:
- resistance to temperature extremes in the range from -50 to + 60ºС;
- resistance to the development of microorganisms when humidity changes;
- unpretentiousness in leaving;
- service life reaches 50 years;
- approximate overall dimensions of the panel are 2x24x366 mm.
Production of wood panels
At the first stage, the pre-processed log is sawn by the transverse or radial method. Then, in the period from 10 days to 2 weeks (the drying period depends on the initial moisture of the tree), it is exposed to high temperatures. Further, with the help of milling machines, the profile and the front surface of the board are directly formed. Next, a comb and grooves are cut. In the next step, the product is trimmed and sorted.
Features of storing wooden options
Do not forget that wood is a very capricious material, therefore it is very important after processing to ensure optimal storage conditions that will not lead to disastrous consequences. The tree must be protected from high humidity.
To avoid damage to the panels due to humidity, the boards are packed in a special heat-shrink film, forming bundles of several lamellas, while leaving the ends open to allow natural ventilation. It should be noted that the board, dried in natural humidity, is much less deformed and cracked. A dry board should have a moisture content that does not exceed 15%.
When choosing, it is worth paying attention to consumer characteristics and cost. Dry lining costs 25-30% more due to the costs of drying, but at the same time it cracks or deforms less.
Given the quality and characteristics of various types of wood, it is possible to divide the panels into grades or classes (A, B, C). This separation is carried out depending on the condition of the wood, the presence of resin pockets and fused knots.
Category data must be reflected on the packaging of the “block house”.
- A - for every 150 cm of length, one knot, two resin pockets and two non-through cracks are allowed;
- B - for every 150 cm of length, no more than four knots, two resin pockets and two non-through cracks are allowed;
- C - cracks, pockets, larger knots are acceptable than in other categories.
The highest quality “block house” belongs to class A.
Stages of fastening panels for house sheathing
When covering the house, it is necessary to observe simple rules and act consistently.
- Before starting work, the material must undergo acclimatization (take environmental properties in order to exclude further deformations, cracks and distortions). For outdoor work, the adaptation period is from 2 to 3 days, for interior decoration - a minimum period of 5 days.
- Thermal insulation and vapor barrier of the exterior walls of the building.
- Preparation of the "block house". Surface treatment of panels with quick and deep penetrating protective agents. For grooves and spikes, this procedure is recommended to be performed twice.
- Directly mounting the panels starts from the bottom of the wall and leads further upwards according to the principle of "tenon into the groove" (tenon — up, groove — down). You can fix the “block house” to the wall with self-tapping screws, studs or special brackets. When temperature and humidity change, the panels can change the density of the material, so cloves are best suited for fastening, as they do not interfere with small displacements.
After facing, it is necessary to re-apply the protective layer on the panel, then update the coating every five years.
Secrets of Masters
In order to reduce the total amount of work, it is recommended to use wide panels with the exterior cladding of the building, which will give the house a stylish appearance. Such panels are difficult to distinguish from a real beam. We must not forget about natural ventilation by stepping back a short distance before starting installation. When re-applying the protective layer, special attention must be paid to the seams and joints.
For external cladding, it is recommended to use a flat "block house" of coniferous species, and for internal - of hardwood. The use of wide indoor panels is not recommended. The estimated cost of finishing work may vary depending on the characteristics and material of the “block house”.
How to choose?
In order to choose the best panels made in accordance with Russian and international standards, and to protect yourself from unnecessary costs, you need to pay attention to several points:
- It’s worth starting with an accurate calculation of the required amount of material, which directly depends on the characteristics and dimensions of the “block house”, not forgetting the error for trimming.
- Great competition among manufacturers in the Russian market does not mean that there are only high-quality panels corresponding to the declared variety. It is necessary to carefully examine the purchased goods for obvious defects (cracks and other damage). But here there are difficulties - you can not unpack the goods if it is packed in film. Only panels located at the edges can be inspected. Inside the package may lurk boards deformed from moisture and improper storage.
- To check for curvature, 2-3 panels are connected to each other, given that there should be no rigid fixation. If possible, be sure to measure the moisture level of the material.
- Panels should be trimmed along the growth of the tree trunk, and annual rings should not protrude from the board to avoid splitting. The edges of the boards must be additionally checked so that they are smooth and without cracks, which are signs of marriage.
- Particular attention should be paid to the "block house", extended in length (milling from several parts of the board). The sections can be of unequal length, adjusted according to the pattern or type of sawing, the connection can be made with glue.
- It is worth paying attention to the presence of mold and other microorganisms.
Any distortions, cracks, irregularities and distortions turn the panels into unsuitable for use and installation. It is worth checking the connecting grooves.
The cost of the “block house” panel depends on several factors, the determining ones of which are the type of wood and geometric parameters. For the manufacture of rocks used, growing in the region of production. However, for an individual order for an additional fee, you can order the production of any material. The cost of tree species common in the middle lane ranges from 150 rubles per m² (pine) to 1250 rubles per m² (oak species).
Classes (A and B) in Russia are very difficult to distinguish visually, respectively, and their price is 20-25% higher. The price for class C is much lower. For an additional cost of 1 m² for class A, forced drying will add.
It is recommended to pay attention to several key points.
- The 300 mm “block house” can be called the most popular and versatile finishing material to date. It is represented by panels of wood, metal, vinyl.
- Due to the variety of materials from which it is made, even the most demanding consumer will find a worthy option that meets personal preferences and opportunities. Among the presented variety, you can choose panels made of wood, metal or vinyl.
- A wide range of characteristics allows the use of a “block house” both for external finishing work with a large temperature difference and at high humidity, as well as for interior decoration.
- When choosing a certain type and class of “block house”, it is very important to carefully examine it, eliminate deformations, and check for chips and cracks.
- During installation work it is necessary to observe certain conditions and not to forget about the acclimatization of the material, processing with protective compounds and natural ventilation, in which case it will last more than a dozen years.
