Norsound's 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 NOR710 also has smoke seal capabilities in accordance with BS 476: Part 31: 1983. It provides a continuous acoustic seal not broken by hinges or latches. This multi purpose seal is perfect for applications that require a smoke and acoustic seal and it is acoustically capable of achieving up to a massive 48dB reduction.

We have cycle tested the NOR710 acoustic door seal up to 1,000,000 opening and closing cycles.

Would I require a separate smoke seal if I use the NOR 710?

No. Since the NOR710 is a continuous acoustic seal it acts as a smoke seal, better in some ways than standard intumescent smoke seals.

What size rout does the seal fit into?

The NOR710 doesn‘t need a rout as it uses self adhesive on its base to adhere straight to the frame.

Can I use the NOR 710 on latched doorsets?

Yes, due to the fitment position of this seal, it is unaffected by door furniture.
