Construction Gaskets for Insulation, Heat & Noise ReductionView Product Gallery

At Seal Methods, Inc., we provide builders with products designed to seal, insulate, and reduce sound and thermal transmission. Our broad line of compressible foam and adhesive tapes, gaskets, and extruded foam profiles are available in a wide range of densities, thicknesses, and adhesive formulations. These materials are ideal sealing solutions for hundreds of construction applications – such as glass & windows, sill systems, exterior wall systems, and metal walls & roof panels, acoustical systems, roofing, and more.

Construction Gaskets

Applied between wood or metal framing members and sub-flooring, exterior sheathing, or interior gypsum board, Norton CSTĀ® Construction Gasket utilize a patented technology to reduce sound and thermal transmission. When used on floors, walls, and ceilings, it gives the room a quiet ambiance – it is proven to reduce noise transmission by up to 90%. We offer solid and foam core butyl mastic tapes in a variety of shapes and dimensions to meet the needs of commercial or residential projects.

Low density closed cellular Sill-Seal material is designed to seal between the sill plate and masonry or reinforced concrete. By reducing air infiltration, it provides a tighter building envelope and promotes energy savings. This product has excellent resistance to weathering, fungi, and oxidation and is available with an optional pressure sensitive adhesive to speed installation.

Window Components

SMI provides virtually any type of pressure sensitive tape for temporary or permanent component attachment. We offer a full line of AAMA-approved glazing tapes for applications such as interior glazing, residential and commercial windows, two- and four-sided structurally glazed curtain walls, and skylight systems. Cellular glazing tapes provide superior long-term sealing, thermal resistance, sound dampening and aesthetics when compared to solid and gunnable materials. Economical options are available for both residential and commercial applications. To facilitate bonding glass and other exterior wall panels to the framing system, we offer Thermal bondĀ® structural spacer tapes. We also offer polycarbonate- and Plexiglas-compatible sealants and adhesives.
