Willseal 150

Willseal 150 is a precompressed, self- expanding polyurethane foam joint sealant that is designed to seal against rain, wind, sound, draft, and dust in primary vertical joint applications. Unlike other conventional methods, Willseal 150 is not susceptible to breakdowns caused by excessive joint movements, joint strain, surface contamination, aging, and general tensile stress-caused failures. It does not dry out, shrink, or deteriorate. There’s no mixing, no masking, no staining, and no mess. Willseal 150 can be installed under many weather and temperature conditions. Willseal 150 can also be used as a redundant seal behind caulk that is not subject to adhesive or cohesive failure.
