LPD Brown Fire and Smoke Intumescent Seal INTRUBFD30S

This brown fire and smoke intumescent seal is designed to improve fire safety while keeping the finish of your door neat and subtle. At normal temperatures, it stays slim and unobtrusive. When exposed to heat during a fire, the intumescent core expands, sealing the gap between the door and frame to slow the spread of flames and hot gases.The built-in nylon pile brush adds an extra layer of protection by reducing cold smoke leakage, drafts, and noise in everyday use. This makes it ideal for both fire protection and day-to-day comfort. The self-adhesive backing allows for quick installation, and the seal can be easily trimmed for a precise fit on site without special tools.For best performance, the seal should be rebated into the door or frame, ensuring proper alignment and long-term reliability. The brown finish blends well with timber doors, making it a practical choice for residential and commercial settings where appearance matters as much as safety.Suitable for 30-minute fire-rated doors, this seal supports safer escape routes, helps maintain fire compartmentation, and contributes to overall building compliance with fire safety requirements.
