SSW Intumescent Wrap Strips

Check up to five results to perform an action.

SpecSeal® Wrap Strips are highly flexible, elastomeric strips designed to firestop combustible penetrations in fire-rated floors, floor/ceilings, and walls. Convenient 12’ (3.7 m) rolls, or individually sized strips facilitate installation and minimize waste. Four grades are available to suit the product to the application.

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 SpecSeal® Wrap Strip begins to expand (intumesce) rapidly to form a dense, highly insulative char. Free expansion varies according to the grade utilized (See Table A). Expansion continues up to temperatures of 1,000° F (538° C)
