NORfast is a revolutionary retro-fit seal.
NORfast provides excellent fire and smoke sealing, in accordance with BS 476 Part 31:1 and BS 476 Part 20:22.
Using 'dual air pocket technology', NORfast creates an effective seal between the door and the stop, which boosts the acoustic performance of the door by up to 42dB.
Designed to include an intumescent strip, NORfast is capable of expanding or swelling (intumescing) under extreme heat, which provides a greater seal in the event of fire.
