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.

Please note that if you have chosen options such as pre-finishing, your dispatch date will be reflected next to the stock item once you've chosen your quantitiy.

In most instances delivery will be made on a weekday. Couriers may however choose to delivery at the weekend during a busy period. As a result of this we are not able to offer a weekend delivery service but this option may be available directly through your courier if they call to arrange a specific delivery time and date. Please note that your delivery will be made to the kerbside. As such, please ensure you are able to move your order to a secure location.

The stated delivery time is based on an order which is placed before 1:30pm.

Due to the time taken for in-house finishing and the possibility of delivery issues in rare cases, we highly recommend waiting to book tradesmen until your order has been delivered.

Many of our orders are delivered on a pallet. It is the driver's discretion whether they take the pallet away with them following delivery. We are unable to collect any pallets after delivery has taken place. We highly recommend using the pallet to support your doors until they are ready to be hung.
