Willseal has a full range of pre-compressed, self-expanding foam sealants that are weathertight, dust-proof, noise-reducing, thermally insulating and UV stable. The Willseal products use a solid piece of foam which allows for internal smoke barriers and waterproof membranes to be placed within the foam. This solid foam also allows for varying depths of 2”, 3” and 4” for the Willseal FR (Fire Rated) products.
Willseal is the original brand of pre-compressed joint sealants. They offer a complete line of pre-compressed sealants and expansion joints to satisfy a wide variety of waterproofing needs.
Willseal products are built for extreme performance through innovative design and materials and are solid sealants with a uniform core: no unbonded lamination, and no cheap filler foams.
Willseal is a company firmly committed to environmental stewardship. Our products contain no volatile organic content (VOC), satisfying the U.S. Green Building Council’s LEED™ Criteria for Indoor Environmental Quality. Willseal is committed to bringing intelligent solutions to our customers, using technology-driven design to create superior sealant systems.
