Home / Workplace Safety / Access Control / Door Release / Door Furniture Product Description This intumescent fire and smoke seal is used to maintain the integrity of fire doors in the event of a fire. The 10mm white seal contains an intumescent material which expands when subjected to heat to form a seal around the fire door, preventing the fire from spreading. The seal also has a brush fitted to it which provides a permanent smoke barrier as smoke travels faster and further than the fire itself. Resists passage of fire for up to 60 minutes Fully tested to BS476:Part 22 Fire Only and BS476:Part 31 Width (mm) 10 Depth (mm) 4 Length (mm) 1050 Specifications MPN ISS10/W Brand FIRECHIEF Product Code 111-1085 Customer reviews No reviews left yet Write A Review Sort byMost RecentTop Rated Delivery & Returns Free UK Delivery over £250Returns Policy: The company operates a 14 day returns policy, products returned in an unopened / undamaged condition will be refunded.
