Since 2005, the TAMAK laboratory, in addition to CBPB testing for compliance with the requirements of GOST 26816-86, additionally tests CBPB for compliance with the European standard EN 634-2 requirements.
All physical and mechanical parameters are controlled by a certified laboratory.
In the construction and design it is necessary to take into account that the incidence of wood in the CBPB composition entails slight deviations in the linear dimensions of the plates in the context of temperature-humidity changes in the environment
The linear elongation of the TAMAK CBPB is 1.5 mm per 1 m. Therefore, in sheeting external vertical structures between the boards, it is necessary to leave the expansion joints (gaps) of 8 mm, and for the inner lining 4 mm.
In horizontal structures, for example, floors, the boards are laid without a gap between them. Thus between CBPB and walls it is necessary to provide a clearance of 10 mm around the perimeter of the room.
Attention! Linear operational changes in size do not adversely affect the quality and durability of CBPB.
The thermal properties of CBPB in Kaliningrad
CBPB, due to the organic connection of wood and cement, is a homogeneous monolithic material without any air entrapment, which provides high thermal conductivity. The thermal conductivity coefficient is 0.216 W/mK.
Therefore, the greatest use of CBPB can be recorded in designs where a combination of high strength and low thermal resistance of the material is required.
Fireproof properties of CBPB in Kaliningrad
Due to their properties, CBPB are widely used in fire-fighting structures. According to Building Rules (SNiP) 21-01-97 CBPB have the flammability group G1 (low-combustible), which is confirmed by the Fire Safety Certificate No.SSPB.RU.OP031.Н.00091.
TAMAK CBPB belong to the group of difficult non-flammable materials of enhanced biostability and are intended for use in the construction of wall panels, slabs, suspended ceilings, ventilating boxes, in the installation of floors as well as window sills, linings, claddings and other construction products.
