SINTOFOIL RT FB
Polyester reinforced TPO/FPA membrane for single-ply waterproofing of exposed flat roofs bonded on the lower face with nonwoven polyester fabric.
Synthetic waterproofing membrane produced by co-extruding a UV resistant elastomerised TPO/FPA thermoplastic olefin and flexible polypropylene alloy, with a polyester net reinforcement bonded on the lower face with nonwoven polyester fabric. 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%. SINTOFOIL RT FB membranes comply with CE marking requirements, if applicable.
Fields of application
Specific use
- Mechanically retained waterproofing on exposed roofs.
- Waterproofing layers applied independently under heavy-duty fixed or movable protection for:
- roofing exposed to foot traffic;
- inverted roofs.
