- Uses
- 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.
- INSS1440 Fire Barrier Caulk will adhere to most construction materials and penetrant items, is installation-friendly, asbestos and halogen-free, and can be painted after full curing.
- Installation Guide
- Ensure the application area is clean and free of oil, loose dirt, rust or scale and is dry and frost-free.
- Install the correct depth and compression of backing material, if required, as detailed within the applicable listed system, allowing for sufficient depth of fill material.
- Using a caulking gun, trowel or putty knife, apply INSS1440 fire barrier caulk into the seams, gaps or voids between forming material and floor or wall surface.
- Tool the sealant surface smooth using a putty knife dipped in water, making complete contact with substrates to ensure an air and smoke tight seal.
- Clean up, as necessary, with water.
- INSS1440 fire barrier caulk cures by water evaporation and is not recommended for use in a wet environment.
