Pyrostrip Interdens is manufactured in multiple formats and available as cut to size strips.
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.
Type 36 – 2mm thick supplied in either 10 or 20mm widths depending on test evidence
Can be supplied in either 1m or 2m lengths.
Type 36 – White, Red, Brown and Black
The product is semi-rigid and is used to seal the gap between the glazing bead and glass as dictated by Certifire/fire test evidence.
