SINTOFOIL RT
Polyester reinforced TPO/FPA membrane for single ply waterproofing of exposed flat roofs.
Synthetic waterproofing membrane produced by co-extruding a UV resistant elastomerised TPO/FPA thermoplastic olefin and flexible polypropylene alloy with a polyester net reinforcing mat. The membrane features contrasting colours on its upper and lower faces, providing a signal layer so that any damage occurring during or after installation will be immediately apparent. Available in BIANCO REFLECTA version, manufactured with the upper side of the membrane (top) in WHITE REFLECTA colour, by means of a treatment developed in mass in the entire layer that covers the top of the reinforcement. This process enhances the reflectance and emission features giving the roof a Solar Reflectance Index (SRI) value that reach 102%. Also available in the fire resistant versions (external fire behaviour), in Broof class according to EN 13501-5: SINTOFOIL RT/FR1(1), SINTOFOIL RT/FR2(2), SINTOFOIL RT/FR3(3) (consult the specific data sheet - SINTOFOIL RT/FR). SINTOFOIL RT membranes comply with CE marking requirements, if applicable.
