Box of 10 Lorient LP1004 Fire Seal Intumescent Strip White

Lorient LP1004 plain intumescent fire seal for FD30 timber fire doors, sold in boxes of 10 x 2100mm lengths. The plain intumescent strip provides fire protection only — when exposed to heat it expands to seal the gap between the door and frame against fire. For fire doors that also require smoke sealing (FD30S), see the Lorient LP1004DS Twin Fin which combines fire and smoke protection in one strip.
