The ventilated facade is marked by an uninterrupted ventilated air chamber between the outer face, which can be made of the most diverse materials and the inner face on which the insulating layer is normally applied. The air chamber provides for the dispersion of water vapor and avoids that it condensate thus preventing moisture; the outer face protects the insulation panels from UV rays and bad weather. 

The polyurethane foam is particularly suitable for this type of application for the very low water absorption values and for the vapour permeability, besides of course the good values of thermal conductivity (λ) and of dimensional stability.

POLIISO^®FB thanks to its excellent reaction to fire (Euroclass B s1 d0) is particularly suitable for the thermal insulation of ventilated facades and buildings subjected to fire prevention.

Laying: anchoring plates to hold the facade's finishing or outer covering are amounted on the inner wall or on the support wall usually made of bricks or cement blocks. The anchoring system consists of a frame made of vertical and/or horizontal bars. Once the bars forming the anchoring system are mounted, the POLIISO^®FB insulation panels are laid by fastening them mechanically to the support wall. This creates a ventilated air chamber with a thickness of about 3 cm between the insulating layer and the outer face. The facade's finish, usually made of thin ceramic, stone or metal plates or tiles, is then mounted on the frame to finish the whole.
