How effective is floor soundproofing?

Floor soundproofing will reduce impact noise, airborne noise or both. All of our acoustic floor solutions are designed to exceed the UK Part E Building Regulations for the passage of sound. (43dB or higher for airborne noise and 64dB or lower for impact noise). Different systems offer different levels of noise reduction depending on the level of noise needed to be blocked and the current construction of the floor. No soundproofing will offer 100% reduction, however installing soundproofing will dramatically reduce noisy neighbour noise. *dB results will vary depending on several factors. Please see our dB blog on why dB results may vary

Does floor soundproofing work both ways?

Floor soundproofing will block impact noise (footsteps) travelling from the room above to the room below. Floor soundproofing can also block airborne noise travelling from below to the room above or from the room above to the room below.

Do I need to soundproof the whole floor?

The short answer is YES as soundproofing is like waterproofing and is only as good as the weakest point. (As sound can travel through very small gaps). If you were to soundproof just part of the floor you would be wasting your money.

How thick is floor Soundproofing?

Floor soundproofing varies in thickness from 5mm to 28mm depending on the type and level of soundproofing required. However, our best-selling SoundScreed is just 28mm thick and performs exceptionally well against both airborne noise and impact noise.

Do you offer an installation service?

Please see our dedicated installation page for more details on different installation options.

Once installed, can I put any type of flooring down?

Yes, however, the best final floor finish for soundproofing is carpet. Our SoundScreed is unique in that no further hardboard layer is needed. Thin hard floors such as laminate and vinyl can also be fitted on top of soundproofing, but some systems may need a 6mm hardboard first to provide a flat stable base. Our Reverso SoundMat is unique in that in the majority of cases no further hardboard layer is needed. Engineered wood floors can also be fitted on top of soundproofing providing it is 18mm or thicker. Bathroom, and kitchen tiles will normally need a flat stable base on top of the soundproofing, depending on which floor soundproofing system has been selected. For specialist flooring (including certain LVT and Vinyl) a self levelling screed or overboard may be needed to meet the manufactures guidance. Please speak to the flooring manufacturer to check. Solid and hard floor finishes will reduce the amount of impact noise reduction achieved by the base layer of soundproofing by up to 5dB.

SoundScreed 25 is a multipurpose flooring product that can be utilised in a variety of different situations:

Direct to floor joists:

To minimise floor height build up whilst improving the airborne soundproofing capabilities of the floor

Secondary Floor Battens:

Used as a structural floor on acoustic cradles and isolated secondary floor battens. The use of secondary floor battens will enhance both airborne and impact sound performance

Floating over underfloor heating:

Used as a floating construction on top of thermal insulation (PIR) above underfloor heating systems with a far greater thermal conductivity than standard chipboard floors

Overlaid on an existing floor:

Used as an overlay board on an existing solid sub floor when floor height is not restricted. Impact performance can be improved by the addition of ProSound ImpactoMat 5
