STI SSW Wrap Strips are highly flexible, elastomeric strips designed to firestop combustible penetrations in fire-rated floors, floor/ceilings, and walls

SpecSeal SSW Wrap Strips are suitable for firestopping combustible penetrants such as nonmetallic pipes or pipe insulation. They are ideal for all common forms of construction – concrete floors, concrete over steel deck, concrete walls, concrete block walls, gypsum board/stud walls, and wood floor/ceiling assemblies. And can be used with restraining collars or as a tuck-in. SpecSeal SSW Wrap Strips are available in a variety of sizes and types to tackle any combustible penetration. SSW Wrap Strips are available in 12 ft. rolls as well as individually pre-sized strips to minimize waste and speed up installation. When installed in conjunction with restraining steel, SSW Wrap Strips are able to collapse non-metallic piping of up to 12 in. diam.

Convenient 12’ (3.7 m) rolls, or individually sized strips facilitate installation and minimize waste. Four grades are available to suit the product for the purposes. These products utilize STI’s fast responding intumescent technology, providing very responsive and highly directionalized expansion. Rapid expansion provides quick closure for burning combustible penetrants. When exposed to temperatures in excess of 250° F (121° C), the STI SSW Wrap Strip begins to expand (intumesce) rapidly to form a dense, highly insulative char. Expansion continues up to temperatures of 1,000°F (538° C).
