Self-Adhered
Polyvap SA G is a self-adhered vapor retarder for use in commercial low-slope roofing applications. Utilizing ADESO® dual-compound self-adhered technology, Polyvap SA G features a polymer modified bitumen upper compound and a proprietary self-adhesive SBS (elastomeric) compound on the bottom. A split release film that protects the self-adhesive compound allows for easy application.
Polyvap SA G is reinforced with a fiberglass mat, and surfaced with aggregate to enhance skid resistance and allow exposure up to 90 days. The rubberized asphalt seals around correctly installed nails on the weathering surface.
