Asphalt weldable underlay roofing felt with bitumen strips for fixing thermal insulation. It is a vapor barrier and a bonding layer for thermal insulation panels.

Application

Papa Termoklej is intended for making a vapor barrier layer on roofs and terraces. The roofing felt allows the fixing of EPS, XPS or PIR / PUR thermal insulation boards after heating the strip in the asphalt glue existing on the top side of the roofing felt. The roofing felt is also used upside down, as an underlay felt for two-layer renovation of an old, damp roofing or as underlay felt on a primed, damp concrete base. After welding the roofing felt on the old roofing or concrete substrate, the spaces between the adhesive strips and the ventilation chimneys provide ventilation. The permissible roof slope is 1%. Papa is tested for reaction to fire as a roof waterproofing insulation in.
