LPD White Fire and Smoke Intumescent Seal INTRUWFD30S

This white fire and smoke intumescent seal is designed to do two critical jobs at once: block smoke movement and respond quickly during a fire event. It includes a durable nylon pile brush that helps stop cold smoke under normal conditions, while the intumescent core activates when exposed to heat.The seal has a discreet white finish that blends neatly into door frames, making it ideal for both residential and commercial settings where appearance matters as much as safety. Thanks to its self-adhesive backing, installation is straightforward with no special tools required. The strip can be cut to size easily, allowing a precise fit around standard door frames.In the event of a fire, rising temperatures cause the intumescent material to expand, sealing the gap between the door and frame. This expansion helps maintain fire compartment integrity and slows the spread of flames and smoke, supporting safer evacuation and better building protection. For best performance, the seal should be rebated into the door or door frame, ensuring a snug and secure fit. Reliable, practical, and easy to install, this intumescent fire and smoke seal is a smart choice for improving passive fire protection without complicating the installation process.
