SINTOFOIL ST
Non-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 uniform UV resistant elastomerised TPO/FPA thermoplastic olefin and flexible polypropylene alloy. 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. SINTOFOIL ST membranes comply with CE marking requirements, if applicable..
Fields of application
Specific use
- Waterproofing layers applied independently under heavy-duty fixed or movable protection for:
- roofing exposed to foot traffic and roof gardens.
- Mechanically retained waterproofing on exposed roofs.
