Interden Strips

Interden strips designed and supplied in the UK

Intumescent low pressure activation, high volume strip ideal for glazing applications within doors or screens, providing up to one hour of fire resistance.

Ideal for door frames and edges, our interden strips have a proven performance record. They are easy to install during door manufacture, or on site and are available in a range of sizes.

In fire conditions, the interden strips will swell to fill the gap between the door and the frame and will continue to re-foam and seal the widening gap as the door deforms under heat.

Product Information

  • Certified to BS476 Part 22 (1987)
