TREMstop™ FBF

Rigid Polyurethane Fire Block Foam to Block/Reduce Air Available for Combustion

TREMstop FBF is a Class III single-component polyurethane foam that is resistant to flame, heat, decay, water, and many chemicals. TREMstop FBF is intended to block or reduce air movement around common small interior thru-wall and fire penetrations during a fire event reducing the amount of oxygen available for flame propagation.
