Norsound NOR850 acoustic door bottom seal The NOR850 is a door bottom wipe seal, which is a great alternative to an automatic drop down seal. It works together with a threshold plate (not included) which is slightly raised so it doesn‘t wipe over the floor, carpet or tiles. It also creates the dual air pockets synonymous with Norsound‘s products. Norsound NOR710 acoustic perimeter seal This revolutionary retro fit seal increases acoustic performance of a standard door simply and effectively. Its design is based on ‘dual air pocket 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 NOR710 acoustic door seal up to 1,000,000 opening and closing cycles.
