NuFlex 814 Firestopping products are all 100% silicone firestop sealants that are designed to out last all water based firestops while providing a water, smoke and toxic gas proof seal. NuFlex firestops have also passed the UL1479 accelerated aging tests for air and water leakage.

GG-200 is a non-sag silicone sealant designed for wall and floor applications. The non-sag property of GG-200 will give you the confidence to apply this firestop sealant to overhead and vertical penetrating item without fear of running materials due to the effect of gravity.

GG-266 is a patented 100% silicone intumescent firestopping technology designed to seal combustible service penetrations in fire-rated wall and floor assemblies. When exposed to temperatures in excess of 300ºF (150ºC), the cured sealant will expand to fill in voids as the penetrating pipe collapses under fire conditions. GG-266 is the ideal “caulk & walk” firestop system.

SL-100 is a self-levelling sealant formulated for floor applications. When used around congested service penetrations where tooling is difficult, the self-levelling property of SL-100 will eliminate the need for tooling while assuring a complete fill of the void.

Type SSC is a pre-fabricated collar designed to seal combustible pipe penetrations in fire-rated walls and floors. The Galvanized metal collar houses a molded silicone rubber intumescent ring. When the silicone material is heated to temperatures above 300ºF (150ºC), it will expand to fill in the void caused by the collapse of pipes under fire conditions.

MW-300 Mineral Wool is friction-fitted into voids, joints or cavities in fire-separations for use as backing material for firestop sealants. MW-300 is pre-sized semi-rigid, mineral felt strip with a nominal 4.5 pcf (72 kg/m3) density.
