Product Description

Regupol 3912 impact noise reduction mat is manufactured using a tough and durable 6mm polyurethane foam, it has been designed to reduce the effects of impact sound at the source. It is a retrofit barrier that is perfect for refurbishments and timber based construction beneath carpets, hardwood floors, battens and T&G chipboard.

Regupol 3912 is lightweight making it quick and easy to install, to get the best results out of the 3912 it’s recommend that it is bonded to the sub-floor or a stiffening layer, if you aren’t applying directly to the sub-floor. The 6mm depth means it reduces construction heights when compared to thicker solutions.

The 3912 has a low-tog insulation rating making it suitable for underfloor heating applications; when using it in an underfloor heating system there are two options to choose from, you can either apply the Regupol directly to the sub-floor then place the underfloor heating system on its surface; alternatively, the Regupol can be placed above the underfloor heating system on a stiffening layer such as a 6mm T&G plywood or chipboard.

Regupol 3912 has been independently tested by a UKAS accredited laboratory to ensure it complies with building regulations in accordance with Approved Document E 2003. It also delivers long term performance without collapse under highpoint loads and is resistance to ageing and deformation.



The soundproofing rating of this product are 23dB impact.

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 impact reduction of 10dB, 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 33dB and after laying the product, the dB volume in the room was recorded at 23dB. This means that the product gives an actual airborne impact reduction of 10dB and a rating of 49dB when used as part of a full floor system.

Who is this product for?

This product is used to sandwich between sub-floors and another base layer to reduce impact noise.

This is particularly suited to reducing impact sound travelling down to the floor below.
