NSSF7 10mm floor soundproofing acoustic underlay used underneath carpet to increase the sound insulation between floors, reduce impact and airborne noise.

The NSSF7 is a 10mm acoustic underlay mat used in homes, offices and public buildings that require additional sound insulation against impact and airborne noise. Combine with DFM acoustic insulation for excellent levels of airborne soundproofing. Lay the NSSF7 over wooden or concrete flooring, predominantly used below a carpeted floor finish, carpets can be laid directly over the NSSF7, if you are combining the product with a carpet underlay the perimeter strips should be used around the edge of the room. Gripper rods are attached onto the strips to raise them up to the correct height of the carpet. Underlay can be laid over the top of the NSSF7. Homeowners or carpet fitters would be able to install this product into homes or businesses for increased sound insulation against footfall and conversation sound coming through separating floors.

NSSF7 is simple to install into any room, supplied in 1200mm x 1200mm sheets it is easy to store and handle. The mat should be laid over the floor in a brick pattern, if you are working to Part E Building Regulations the NSSF7 should be bonded to the floor using a suitable adhesive. Cut the NSSF7 with a sharp knife or a pair of heavy duty scissors to fit any shape.

If you have a new build or conversion project that has failed a pre-completion sound test the NSSF7 can be used as a remedial treatment for the floor to increase the sound insulation of the separating floor.
