Polyset Roof Seal is a low-pressure, two-component spray polyurethane foam used to temporarily seal new roofing membranes to the existing roof system. The seal protects the membrane against moisture intrusion during installation. It can also fill gaps and cracks to reduce air leaks and thermal breaks.
Comes in a portable, disposable kit with a Handi-Gun dispenser and temperature warning nozzles.
