DESCRIPTION
The roofing assembly / material information published in the RCABC Roofing Practices Manual does NOT represent a complete set of the manufacturer’s data or specifications. The preparation of a detailed specification is the responsibility of the design authority.
PERMA-BOARD is a semi-rigid waterproof sheet with a rubberized asphalt core sandwiched within two layers of fibreglass reinforcement. Available with a smooth poly film surface finish or a sanded finish. PERMA-BOARD is compatible with all asphalt roofing systems and is unaffected by moisture and will not rot.
PERMA-BOARD Asphalt Base Board / Overlay
| Uses: | PERMA-BOARD is designed to be used as an overlay to insulation and as a base for modified, built-up and single ply membranes. Elastomeric roofing membranes or built-up roofing may be heat welded or hot mopped directly to PERMA-BOARD, creating a thick waterproofing layer. The asphalt board becomes an integral part of the roof membrane making it stronger and more puncture resistant than it would otherwise be. | |
