LOGICROOF P-SR
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 elastomeric TPO/FPA thermoplastic olefin and flexible polypropylene alloy.
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.
Fields of application
- LOGICROOF P-SR is designed for corners reinforcing and sealing of connections between different roof elements such as piping, funnels, aerators and other protruding objects.
