Firestop Caulk INSS1440 Fire Barrier Caulk is a single component water-based acrylic intumescent firestop sealant caulk. INSS1440 Listed designs use less product and offer exceptional performance, making it more cost effective than other traditional firestop caulkings. The product’s fast expansion technology quickly fills voids, offering excellent protection from fire, heat transfer, smoke and gasses. INSS1440 is used for sealing gaps around single or multiple penetrations through interior walls and floors, or for sealing gaps around doors and window frames in critically fire rated structures.
