Pyrostrip Interdens is manufactured in multiple formats and available as strips and sheets.
When exposed to fire, the product exerts a two phase expansion at 150ºC and then at 300ºC, the resulting foam acts as both an insulator against radiant heat and a barrier to fill gaps in fire resisting structures.
Standard thicknesses Type 5 – 0.6mm, Type 15 – 1mm and Type 36 – 2mm
Maximum sheet size 2000mm x 1020mm for all above grades. We can manufacture to size and cut to shape as required.
Type 5 – White
Type 15 – White, Brown and Black
Type 36 – White, Red, Brown and Black
The product is semi-rigid and can be used to seal gaps around partitions, doors, grooves in structural components, glazing and for ironmongery protection.
Pyrostrip Interdens has undergone fire tests globally, in the UK it has been successfully tested to BS476 Part 22 and BS EN 1634.
In addition, IFSA have conducted ageing tests as part of an ongoing programme in the UK and Germany.
