MST from EMSEAL is clean-handling, mess free and more reliable way to seal and insulate window and door perimeters that using canned spray foams.
Emseal window and door sealants are self-adhering tape seals made from resilient, open-cell polyurethane foam impregnated with a water-based acrylic-modified asphalt emulsion (AST Hi-Acrylic) or a water-based, acrylic impregnation (MST). They replace and outperform liquid sealants, butyl-tape sealants and closed-cell closures.
Emseal tapes have been the sealants of choice of building component manufacturers and discerning installers worldwide for more than 30 years.
How it Works – The EMSEAL Advantage
The open-cell foam is impregnated, compressed and shipped in reels. The stored strain-energy of compression in the foam means continuous back-pressure is exerted against surfaces to be sealed. This pressure, combined with the adhesive nature of the impregnation, assures reliable adhesion to both substrates. As the sealed components shrink and expand with seasonal temperature changes, long-term sealing contact with the substrates is maintained.
At installation the tape is held to a level of compression suitable to the intended application. Typically, higher compression levels are required for watertightness in water run-off applications; lower compression can be used to maximize insulation advantage.
