LOGICROOF P-GR FB

Fiberglass 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 fiberglass 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 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 reach 102%.

Fields of application

  • Waterproofing of flat roofs in adhered roof systems.
  • Waterproofing layers applied independently under heavy-duty fixed or movable protection for: roofing exposed to foot and vehicular traffic; roof gardens.
