How to soundproof floors
Take a look at our guide on how to soundproof floors with Noisestop Systems range of floor soundproofing products. We help you to reduce airborne and impact noise between floors by increasing the sound insulation between floors. Find out which is the best soundproofing materials for soundproofing timber and concrete floors. This article will explain how to soundproof a floor if you are a homeowner or an experienced developer. We offer solutions on how to soundproof a floor against noisy neighbours while meeting part E building regulations.

What type of floor are you soundproofing?
The two main floor construction types are timber joists and floorboards, or concrete floors. Concrete floors have a high level of mass and will block airborne sounds (conversation, television). Impact sound (footfall, moving furniture) will transfer through the floor to the room below. If your floor is timber joist and floorboards, both impact and airborne sounds can be a problem.
Stop airborne sounds between wooden floors with acoustic floor insulation
Suppose you want to stop airborne sounds through a wooden floor; use acoustic floor insulation between the floor and ceiling joists. DFM acoustic insulation between floor joists is the best way of reducing airborne sound between floors. We recommend using 100mm of acoustic floor insulation and a density of between 60kg/m³-80kg/m³ to increase the soundproofing between floors.
Stopping airborne and impact sound will result in the highest levels of sound insulation or both timber and concrete floors. Acoustic underlays are the most popular method of soundproofing floors. The combination of mass loaded vinyl sheets and acoustic foams ensures airborne and impact sound is reduced when applied to timber or concrete sub-floors.
If you don’t want to lift floorboards, an alternative method would be to lay Noisestop Barrier Shield over the floor. A high-density mass loaded vinyl sheet that will reduce airborne sounds. These mats are quick and easy to lay and will increase airborne floor sound insulation.
How to soundproof timber floors
To stop impact noise through timber floors, you will need to lay either an acoustic mat or a floating floor. Acoustic underlay matting will absorb impact sound before it transfers into the structure of the floor. These underlay mats will also reduce airborne sound transfer between floors with timber joists and floorboards.
Our range of floor soundproofing mats, the Noisestop F7, Noisestop Acoustic Underlay and the Noisestop F7+, are laid directly over wooden floorboards. Use acoustic underlay mats below most floor finishes including, carpets, laminate flooring, engineered floors, tiles and vinyl. You should check the individual floor soundproofing products regarding suitable floor finishes. Soundproof underlays are used to ensure separating floors comply with current Part E Building Regulations.
How to soundproof concrete floors
As we mentioned earlier, concrete floors have a good level of mass and density. This ensures airborne sounds such as talking and conversation will be blocked. Impact sound such as footfall and moving objects will transfer through a concrete floor. Using a resilient layer over the concrete floor is best to reduce impact sound from transferring through concrete flooring. The Noisestop Mat is rolled out over concrete flooring as a resilient layer between the concrete and finish floor. The composition of the mats will absorb impact sound before it transfers into the concrete sub-floor.
An alternative method of soundproofing concrete floors is to use a floating floor product. The Noisedeck 27 floating floor is used over concrete flooring to isolate the concrete sub-floor from the finished floor.
