Intumescent fire door seals fit into a rebate on the fire door or frame. They expand to many times the original size and fill the gaps around the door with a flame-tight seal for 30 or 60 minutes, depending on width of the Intumescent strip. All of the intumescent strips on this page are 20mm wide x 2.1m long x 4mm deep which is enough for a 30-minute flame tight seal. Each type of strip is available in two colours white and brown.


Fire Only – These are a standard form of intumescent strip

Fire and Smoke – Has a nylon pile to stop smoke as well as the standard intumescent strip

Dual Bladed -  These differ from the smoke seals by having black twin rubber blades in place of the nylon brush that not only stops smoke but draughts as well.


Please note images are for illustration purposes only, if you require the wooden lining set click here for product details. You will require approximately 5m to seal around a standard size door.
