Clapboard has been one of the favorite finishing materials for a long time. Thanks to her, cozy, warm and original interiors are created.
What is lining
Clapboard - a long planed board. It has a groove and tongue for mounting. The material is environmentally friendly, because it is made of wood. The characteristics are close to those of wood: durability, ease of installation, high-quality sound insulation.
Used lining for interior and exterior walls, ceiling. In addition, it can be used for the construction of terraces, gazebos, baths. Thanks to its good sound absorption, even the walls in cinemas are sheathed with it.
Currently, there are several types of lining:
Regular (also called "euro lining") - has special grooves on its surface that are necessary for ventilation
American - resembles a wooden beam. This view is attached only in the horizontal direction. It is usually used for exterior decoration of buildings
Block house - imitates a round bar
What lining is made of
Traditional material for the manufacture of lining -wood. Various species are used, both coniferous and deciduous.
Among conifers, the most common is pine. Spruce is also used, but much less frequently. This is due to the fact that spruce has a loose structure.
All grades of pine paneling are suitable for indoor use and exterior wall cladding. But in some rooms (for example, a steam room in a bathhouse), such material is not recommended. But spruce lining is resistant to moisture and mold, so it can be used in places where moisture can get in (baths, balconies, open terraces).
Alder, ash, maple, aspen, linden are used from hardwoods. Slightly rarer walnut and oak. Clapboard made of aspen, as well as premium wood species, can be purchased online at vagonkavsem.ru. The goods are delivered in the Russian Federation in a shrink film. Elite species are made from larch. Linden and alder wood never heats up and does not burn the skin, regardless of the air temperature. Therefore, they are often used for lining walls in the steam rooms of baths and building shelves there.
Recently, lining made of other materials (for example, plastic) has also been produced. Such a building material is conditionally called "lining" due to the presence of a "groove-comb" fastening system.
Varieties of lining
Lining is produced in accordance with the standards defined by GOST and TU (technical specifications). If GOST is common for all enterprises, then TU is developed by each manufacturer independently. That's why it's harddivide the lining into separate types. Each manufacturer may have their own.
The quality of the finished material depends on the quality of the selected raw materials. Therefore, such characteristics as the presence of knots and resinous pockets, the blueness of raw materials, existing cracks, etc. are chosen as the basis for dividing the lining into grades. Depending on this, the following types of lining (or classes) are distinguished:
Extra variety (also called "highest" or "premium")
First grade (class A)
Second grade (class B)
Third grade (class C)
Products of different varieties are made using the same technology. Their division occurs after sorting, as the lining types differ only in the presence of external defects.
Extra variety
This lining (grade "extra") is characterized by the complete absence of any defects. It has no knots, no cracks, no chips. Most often, this variety is made by splicing. This is due to the fact that it is very difficult to make perfect boards from a single piece of wood. Their number is very small. This variety is considered elite, it is used to decorate the interiors of rich country houses.
Accordingly, such lining has the highest price - the highest grade. For its safety, manufacturers often pack it in a vacuum. In this way, they reduce the likelihood of damage to the product (chips, deformations) during transportation and storage. The kit usually includes special fasteners for mounting. The premium lining does not need to be adjusted, it will fix perfectly. During installation, you need to be careful not to damage the surface of the material, which is covered with a protective varnish. The lacquer finish further enhances the beauty of the wood.
When buying, you must be careful. Visually inspect the material to avoid deception. Do not trust only the inscriptions on the label. There are times when there are ideal boards on top of the package, and lower quality boards on the bottom. Sellers who are confident in the quality of the material will not obstruct inspection.
First grade
With top-class lining, its characteristics are comparable to class A lining. Grade 1 from some manufacturers is often better than the highest from others. This is due to discrepancies in the requirements of technical specifications during production. Therefore, in such situations, you need to focus on the appearance of the material.
Differences of the first grade lining - in the absence of falling knots and through cracks. Small and necessarily non-through cracks occupy an insignificant part of the boards. Also characteristic is the absence of blue, rot and black dots.
Knots that are on the material must be light, he althy and not falling out. Their size does not exceed 1.5 centimeters in diameter. Drop knots must be he althy, intergrown and no more than 0.5 cm in diameter.
Cracks are allowed up to 9.5 cm long. They are necessarily not through, not plastic, and go to the end of the board.
Defects of a product of this classno need to hide. It is enough to treat the surface with a decorative varnish (oil, wax), which will emphasize the natural lines of wood.
Larch lining (grade 1, like the highest), perfect for interior decoration of residential premises.
Second grade
This lining (grade 2) is characterized by the presence of visible defects. There are dents, cracks, chips. But their size does not exceed 5 cm per 1 meter running board. On the surface of the product there is blue (up to 10% of the volume), knots, resins, cores. At the ends, a non-stitch is acceptable, which does not interfere with installation.
Knots do not exceed two centimeters in diameter, their number is up to one per linear meter of material. If the knots are black, then their diameter should not exceed 1.5 cm. Rotten and falling knots are not allowed.
Plast cracks are allowed, extending into the end, with a length not exceeding a third of the entire length of the board. Through cracks - no more than 30 cm in length. The length of formation through cracks is no more than 15 cm with a width of up to 1 mm.
Places with blue, coloring, pitching are allowed one per board, if their size does not exceed 10x20 cm.
Most defects occur during the manufacturing process. Existing cracks should not be through or go to the end of the board. Possible rot up to 10% and a wormhole (up to 3 per linear meter). For this grade, any defects are acceptable that do not interfere with the installation of the material.
Existing flaws are usually hidden by grouting and painting in dark colors.
This class of liningis a budget option suitable for most of the population.
Third grade
For certain rough work and finishing of utility rooms, lining is also used. Grade 3 is the most suitable option. The low quality of the products explains the minimum cost.
During installation, lining of this class must be adjusted and painted in order to hide serious surface defects. These can be falling knots, through cracks, core, bark remnants, chips. Material defects occupy most of the surface.
Comparative table of lining by grades
Distinctive characteristics, due to which lining types are distinguished, are most conveniently compared using the table.
| Variety "Extra" | 1st grade | 2nd grade | 3 grade | |
| Presence of knots | Invalid | Up to 1 he althy, light and captive knot per 1 linear meter | He althy are acceptable. No more than 1 drop-down (up to 1.5 cm diameter) per linear meter | Eligible |
| Cracks | Invalid | Acceptable (not through) | Acceptable (not through) | Eligible |
| Core | 3-5% | Less than 20% | Eligible | Eligible |
| Rot | Invalid | Invalid | Less than 10% | Eligible |
| Resin pockets | Invalid | Less than 5cm | Eligible | Eligible |
| Wormholes | Invalid | Invalid | Less than 10% | Eligible |
Price differences between types of lining
Differences in the quality of the material and the presence of defects leads to differences in prices for lining. Boards that look the same may differ in price. This may be due to the way the material was dried. The board dried in the usual way has natural moisture, it is heavier, but almost half the price. Kiln dried material (lighter) is more expensive.
Thus, class A pine lining, dried in a chamber, costs about 200-450 rubles per 1m2, and dried naturally - 130-300 rubles. Dry material from pine grades B and C will cost 180-350 and 140-250 rubles per 1m2 respectively.
The price of larch lining is approximately the following (per square meter):
- Highest grade - 1200 rubles and more.
- First grade - 550-900 rubles.
- Second grade - 400-750 rubles.
- Third grade - 330-600 rubles.
Lining, regardless of grade, is a beautiful and environmentally friendly material,which is easy to use. But when choosing the necessary material in the store, care should be taken. It is better to spend a little time checking the purchased products, whether they correspond to the declared grade. Otherwise, you may be wrong. This will affect the aesthetic features of the room, which will not look exactly as planned.
