Expanded polystyrene boards in the “FAÇADE” category mean high quality thermal insulation creating a barrier to heat flow, which reduces heating costs. This is definitely the most frequently used thermal insulation material for walls of residential and commercial buildings, constructed with the application of different technologies, and particularly popular in the ETICS (External Thermal Insulation Composite System).
A variation of the HOT DOTTED expanded polystyrene with enhanced insulation characteristics. SILVER façade is recommended for thermal insulation in the ETICS.

- filling expansion joints.
How to install polystyrene boards
After fixing to the external wall, EPS boards should be immediately covered with the outer layer: the reinforcing layer and plaster in thermal insulation systems, outer panels in three-layered walls, etc., in order to protect the EPS against direct operation of weather conditions (UV radiation) which have a destructive effect on EPS surface.
SILVER façade boards demonstrate increased resistance to UV radiation, but in prolonged exposure to weather conditions, the surface layer of the boards may be covered with a yellowish coating. In such a case, before the reinforcing layer is applied in the ETICS system, remove the coating with fine sandpaper until there are no loose particles on the surface which could weaken the adhesion to the polystyrene.

Packaging, storage, transport of EPS
SILVER façade boards are supplied in the original manufacturer's packaging only. The label on the packaging contains the following information: product name, manufacturer's name and factory name, production date, Standard EN 13163 number, code according to this standard, declared technical characteristics. SILVER façade boards should be stored in a manner to protect them against damage and weather conditions.
