This revolutionary friction fit seal increases acoustic performance of a standard fire rated door simply and effectively. Its design is based on dual air pocket technology which acts in the same way as double or triple glazing.

The NOR710SR also has smoke seal capabilities in accordance with BS 476: Part 31: 1983 and is unaffected by door furniture including hinges and latches. We have cycle tested the NOR710SR acoustic seal up to an impressive 1,000,000 opening and closing cycles.

The NOR710SR has been developed to rout into the stop section of the door frame.
