FlameSafe® Intumescent Wrap Strip
Resilient Strip Designed to Firestop Combustible Penetrants
The FlameSafe® Intumescent Wrap Strip (FSWS) is a highly flexible, resilient strip designed to firestop combustible penetrants in fire-rated walls and floors. Highly intumescent, the FSWS rapidly forms a dense char to prevent the spread of fire, smoke and toxic gasses when exposed to temperatures in excess of 250°F (121°C). The FSWS continues to expand up to 1000°F (538°C). Available in 12' rolls, the FlameSafe® Wrap Strip is available in two widths and is easy to cut and fabricate.
US Patent No. 6,207,085.

FlameSafe® Joint Strip
FlameSafe® Joint Strip is a flexible, highly intumescent firestop material used in concrete and masonry floor and wall joints up to 1" wide. It forms a strong insulating char that prevents the passage of flame, smoke and hot gases between joints. FlameSafe® Joint Strip is ideal for stadium construction, tilt up panels, curtain wall panels and all concrete and masonry wall and floor construction joint applications where a fire-rated joint is required. US Patent No. 6,207,085.
