This revolutionary retro fit seal increases acoustic
performance of a standard fire rated door simply and effectively. Its
design is based on ‘dual air pocked technology‘ which acts in the same
way as triple glazing. The NOR 710 also has smoke seal capabilities in
accordance with BS 476 Part 31:1 and is unaffected by door furniture
including hinges and latches. We have cycle tested the NOR 710 up
to 100,000 opening and closing cycles.
