Soundproof Flooring Underlays

Noisestop Systems provide a range of soundproof flooring underlays. Floor soundproofing for concrete and timber floors, soundproof underlays will help stop impact and airborne noise between floors.

The best method of soundproofing a floor to stop impact noise is to stop the impact noise at the source. Block and absorb sound before it transfers through the floors structure with soundproof flooring underlays. The best way of doing this is by using a floor soundproofing underlay. Acoustic mats will reduce the energy generated when an object hits the floor. This type of soundproofing flooring combine mass loaded barrier mats and acoustic grade foams. This combination of materials will block, absorb and reduce noise through all types of floors.

What is a soundproof flooring underlay?

Floor soundproof underlays are designed to reduce impact and airborne sound transfer through timber and concrete floors. The way they do this is due to the composition of the materials. An effective soundproof underlay will combine mass and absorption, this will reduce impact and airborne sound transfer between floors.

Acoustic underlay mats combine mass loaded vinyl sheets with acoustic absorbent foam. Most soundproofing underlay mats have a layer of foam that is laminated to one or two layers of mass loaded vinyl. The mass loaded vinyl will reduce airborne sounds due to the density of the material, the foam layer absorbs impact sounds, reducing the sound of footfall transferring into the floor.

Soundproof underlay products

Noisestop Systems provide a range of soundproof flooring underlays, Noisetop Acoustic Underlay, Noisestop F7 and Noisestop F7+ all of which can be used below the most common floor finishes including, carpet, laminate flooring, engineered floors, vinyl and tiles. If you are using a solid floor finish that is less than 15mm thick you should combine the underlay with a 6mm or 9mm ply sheet or MDF board to ensure a solid base for the floor finish to reduce any movement of the flooring.

Using a soundproof underlay to comply with Part E Building Regulations

Building regulations require new build and conversion projects meet certain impact and airborne requirements, see the table below. To ensure floors meet the regulations you will need to use an acoustic underlay as part of the solution. If the separating floor is timber you will have to combine the underlay with 100mm of acoustic insulation, at a density of 60kg/m³ between the floor joists. The ceiling below should be double boarded using two layers of acoustic plasterboard hung from an acoustic hanger, attach soundbreaker bars to the ceiling joists to isolate the plasterboard from the ceiling joists.

Soundproof concrete sub-floors with acoustic underlays to absorb impact sound transfer that occurs through this type of construction. The density of concrete normally means that airborne sound is blocked by the sub-floor, but impact sounds will still vibrate through the concrete flooring.
