EVAFOL SK vapor barrier
EVAFOL SK is a low fire load air and vapor barrier designed specifically for flat-sloped roofs. It consists of a multi-layer aluminum composite with tear-resistant fabric reinforcement. The underside of the membrane is equipped with a self-adhesive layer, which is protected by a PE release film. EVAFOL SK can be used as a low fire load vapor barrier in roof layers in accordance with DIN 18234. It is only suitable for mechanically fastened roof structures or for laying roof layers under ballast.
