Designed to fit into a kerf (saw cut) in the door stop, this perimeter seal can increase the acoustic performance of a standard fire door whilst also providing additional protection against cold smoke.

It consists of a semi-rigid base with 2 flexible blades of optimum angles, these flexible blades act like triple glazing giving maximum acoustic performance along with smoke seal capabilities compliant with BS 476: Part 31: 1983 and energy saving properties.

The NOR710STOP provides a continuous acoustic seal not broken by hinges or latches and is also highly durable being tested to 1,000,000 cycle tests.
