Klober Permo® extreme RS SK2 is a non-permeable, taped underlay for increased demands on rain tightness on pitched roofs. This can be used on minimum roof pitches of 12.5 degrees for interlocking tiles, 15 degrees for slate and 22.5 degrees for plain tiles. The high-temperature stability also enables Permo® extreme RS SK2 to be can also be installed under Solar Panels (In-roof system). Gluable two-layered underlay with monolithic TPU coating on extremely tear-resistant PES fleece ƒƒsd-value 0.08 m Surface weight 240 g/m2 Meets the requirements as a roof support system with improved raintightness according to ÖNORM (Austrian standard) B 3661/B 4119 (with rule exception roof pitch >15° and snow load <4 kN/m²) Meets the requirements as a roof support system for extreme loads according to SIA (Swiss Society of Engineers and Architects) 232/1:2011 Double self-adhesive strips permit permanent wind and waterproof sealing of overlaps (shear resistance > 300 N tested) High-temperature stability at peaks up to 100°C and highly UV-resistant Fleece with capillary stop controls the formation of condensation water Robust PES fleece ensures improved mechanical load capacity, thus facilitating the use on sheathing Sealing edge provides good overlapping and improved water drainage High water tightness and tested against heavy rain Use with Klober accessories is recommended.
