Nowadays, in addition to the improvement of heat insulating properties of buildings, a continuously higher emphasis is placed on the protection of wall against moisture and noise and there is a visible effort to improve the aesthetic look of buildings. In the heated rooms of residential and administration buildings the relative moisture is 60% and it is pushed to the exterior surface of the wall where the vapours condensate. This increases the heat conductivity of the wall where the water freezes and increases its volume and thus damages the plaster. In interiors moulds may develop. The optimum solution of these problems is use of ventilated facade systems. Ventilated facade systems with cement bonded particleboards CETRIS® represent one of the applications of CETRIS® boards in building industry for weather protection of peripheral walls.
