The soundproofing ratings of this product are 49dB impact and 54dB airborne.

These figures aren’t a measure of the reduction that the product gives, but is the figure that you would get following a soundproofing test, on the same or a similar full floor set-up to the one used during testing (not just the product in isolation).

Please see the product specification for more details on how these figures were achieved.

Effective Reduction

This product will give you an airborne reduction of 7-9dB and an impact reduction of 20-22dB, when used as a standalone solution (not taking into account the full floor system).

Results are recorded by implementing a 100dB volume in a first floor room, the dB volume is then recorded in the room below and then again when the product is in place. In this instance the airborne dB volume in the room below prior to laying the product was 56dB and after laying the product, the dB volume in the room was recorded at 49dB. This means that the product gives an actual airborne reduction of 7dB and rating of 49dB when used as part of a full floor system.

Who is this product for?

This product is ideal for both domestic and commercial properties, designed for its abilities to reduce both impact and airborne noise.

If you’re looking to reduce noise from neighbours upstairs or downstairs, this product is ideal for you!
