Engineered for safety and compliance, this intumescent strip expands when exposed to heat, helping to seal gaps and slow the spread of fire and smoke through door assemblies.

Ideal for use in fire rated doorsets, this strip is commonly installed in residential, commercial, and public buildings where fire protection is required. The 10mm x 4mm profile provides a reliable seal within routed or rebated grooves, ensuring a secure and professional fit.

Manufactured from quality intumescent material with a clean white finish, this strip offers both functionality and a discreet appearance, blending neatly into door frames. Supplied in a 2.1 metre length, it is suitable for standard door sizes and can be easily cut to length for precise installation.
