Roof Seal

Polyset® Roof Seal low pressure, two-component spray polyurethane foam (SPF) is specifically designed to provide a temporary seal of the new roofing membrane to the existing roof system. Polyset Roof Seal will protect the roofing membrane against the intrusion of water and other elements until the roofing job resumes. Polyset Roof Seal can also be used to fill gaps and cracks of various sizes to reduce air leaks and thermal breaks. Polyset Roof Seal is available in a portable, disposable kit and includes the patented Handi-Gun® dispensing unit and ColorWise® Temperature Warning Nozzles.

This product is formulated utilizing an HFO blowing agent which is part of our ongoing commitment to developing foam chemistries with lower global warming impact and enhanced product performance.
