Few other structural secondary building components carry such a heavy safety load, but Willseal products are up to the task; built for extreme performance through innovative design and materials:
Willseal products are solid sealants with a uniform core; no unbonded lamination, and no cheap filler foams.
Exceptional Life Safety
Just about any product installed in a new structure can pass a safety test, but what about three years later? Traffic and other friction can wear silicone seals off the outer layer of lesser products, exposing the foam and allowing smoke through. Our fire-rated systems offer a first-in-class smoke barrier impregnated into the foam, so they don’t need such intumescent outer sealants. Our design provides superior security and viable escape time.
Outstanding Moisture Resistance
Willseal horizontal seals contain a specially designed water barrier, laminated internally and tested to 30 PSI of head pressure.
