The main difference between the imitation of the beam is its large width, which can reach 180 mm. Using this material, you can simulate a wall from a whole beam. Connection method – shpunt. Various breeds of trees can be used for manufacture, but the most popular are pine and larch.
Pine is popular because of its low price, and larch due to resistance to decay. Therefore, the material from larch is more often used as a sheathing that does not need special impregnation or antiseptic processing as a protection.
The material has a different classification:
The highest grade belongs to boards without knots, deformations and oblique. No defects and cracks are unacceptable here.
In class A is allowed from 1 to 3 non -flinged knots. But cracks and the presence of tarry pockets are still unacceptable.
Imitation of the beam is mounted in several ways. First – according to a galvanized profile or wooden crate. Another option used more often is the external cladding of the building. In the process, it is advisable to leave a gap of several cm between the surface from the back of the board and the surface under the board. This will serve as ventilation for walls, which will prevent them from decay or deformation, which can form due to humidity. Metal brackets are used as fastenings, which are fixed with the ledges of the boards. Approximately they need up to 10 pieces for each m. sq. You can fix the material both vertically and horizontally. To prevent moisture in the latter case, imitation of the beam is mounted upward. Pine is treated with an antiseptic, varnish or other protective coating.
