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 SoundDeck is just 26mm 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. 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.

ProSound™ SoundDeck 28

The SoundDeck 28mm is a cost effective solution in reducing impact and airborne noise on timber floor structures. Commonly used as an overlay board floating on top of existing timber floorboards. It can also be used directly on floor joists as an upgraded floorboard replacement.

Particularly suited to passing Part E Building Regulations with a resilient acoustic ceiling system like the ReductoClip Ceiling Solution below.

SoundDeck 28 provides a strong, level and stable base for hard floor finishes which removes the need for a stabilising layer, helping to reduce installation time and costs.

Whether you require peace and quiet from noisy neighbours living above or below, or privacy between floors within your own home, then SoundDeck 28 is an excellent solution as part of a floor and ceiling system.
