LOGICROOF P-RP 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 reinforcing mat bonded on the lower face with nonwoven polyester fabric. The membrane features contrasting colors 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 the BIANCO REFLECTA version, manufactured with the upper side of the membrane in WHITE REFLECTA color. This enhances the reflectance and emission features, giving the roof a Solar Reflectance Index (SRI) value that reaches 102%.
Fields of application
- Waterproofing of flat roofs in adhered roof systems.
- Waterproofing layers applied independently under heavy-duty fixed or movable protection: roofing exposed to foot traffic; inverted roofs.
