This revolutionary friction 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 double or triple glazing.

The NOR710SR also has smoke seal capabilities in accordance with BS 476: Part 31: 1987 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.

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

No. Since the NOR 710SR is a continuous acoustic seal it acts as a smoke seal, in fact in some ways acting better than standard intumescent smoke seals!

What size rout does the seal fit into?

The NOR 710SR will fit into a standard kerf fitting of 3mm wide and 8mm deep into the frame.

Can I use the NOR 710SR on latched doorsets?

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