Soundproof Floors 

Impact and Noise Insulation

Impact noise is a major problem with floors even where carpet is installed. This can be a noise problem particularly in residential units as overhead footsteps are transmitted as noise to the unit below.

There are various soundproofing methods to significantly reduce this impact noise and the selection of sound proof materials depends on the type of floor - slate, timber, tiles, carpet etc.

Acoustic underlay can be installed at build stage when planning a new home or commercial building or as a retro-fit solution.  

How to Soundproof your Floors

To successfully soundproof a floor you need to add a layer of acoustic underlay to isolate and block both the impact and airborne noise.  This result cannot be achieved with all impact noise products.  Very few are able to do both.  

Depending on your subfloor type (eg Timber or Concrete) and the finished floor material (eg Tiles, Hardwood, Floating timber or Carpet) our solution will vary.  If you can advise us of both, we can recommend the best options to minimise noise transfer via the floor.

Please note it is very important that you do not allow Hardwood or Tiles to touch the wall or skirting boards in the final installation as this will allow noise to structurally transmit down the walls.

Ceramic Tiles

AcoustaMat 700 Density

AcoustaMat 700 density is suited for ceramic installations where a screed bed is required over the acoustic underlay. The 700 density AcoustaMat is 100% recycled tyre rubber, which bears higher elasticity at a lower density which allows for better attenuation in this application over higher density underlays.

AcoustaMat 720 Density - Cork & Rubber

AcoustaMat 720 density cork and rubber is the underlay that should be used in ceramic applications where the ceramics are adhered directly to the underlay. In ceramics it is paramount that there is minimal flex in the floor, which a 100% rubber underlay cannot guarantee. The cork in this underlay provides crucial stabilising piers, to ensure cracking does not occur.

Timber Flooring

AcoustaMat 720 Density - Cork & Rubber

AcoustaMat 720 density cork and rubber for engineered timber floors is made up of a combination or recycled rubber and cork. Rubber and cork compounds are one of the oldest and most recognised acoustic products on the market, introduced over 50 years ago. As a result it has become a leading product for use in applications where timber flooring is directly adhered. Our 720 density cork and rubber is manufactured with a higher percentage of real rubber providing better impact noise and vibration dampening performance.

AcoustaMat 850RG Density

The "RG" in AcoustaMat 850RG stands for "re-grind", a rubber by-product of the manufacturing process of our rubber products. By using a percentage (approx. 30%) of re-grind rubber in our AcoustaMat, we are ensuring no rubber ever goes to waste from our manufacturing facility. Testing has confirmed that our 850 density rubber underlay is just effective as similar cork or rubber combinations and while cork and rubber may be more recognised by the industry, we recommend re-grind underlay where possible for greater environmental responsibility. By using our re-grind underlay, you are also supporting the environment and ensuring that none of our products end up in landfill.

Using many variations of timber flooring, our recommendation is AcoustaMat 850RG, as an underlay with high acoustic and vibration performance.

Vinyl Soundproof Flooring

AcoustaMat 930 Density - Cork & Rubber

Our AcoustaMat 930 density cork and rubber is the highest density acoustic underlay on the market and as such is seen as an innovative solution for acoustic performance and stability under vinyl.

AcoustaMat 930 Density - Cork & Rubber

In all vinyl applications, we recommend AcoustaMat 930 cork and rubber for the best results as vinyl is an impressionable surface and requires less flexible underlay. The higher density rubber combined with cork in the underlay help to provide a stable underlay in vinyl plank applications, allowing for impression resistance against high point loading, such as high heels and chair wheel castors.

Soundproof Carpet

AcoustaMat 850RG Density

AcoustaMat 850RG is our recommended acoustic underlay for carpeted applications, and can be used in conjunction with carpet underlays where required. The higher density allows for the effective acoustic results at a minimum thickness, keeping a low build height when used with carpet underlay.

Silent Step 

Silent Step is a new generation of acoustic carpet underlay, comprising a flexible mass-loaded barrier, fused onto a high density premium foam underlay. The combination of these two products allows Silentstep to reduce the transmission of footfall and impact-generated noise.

Silentstep was developed to meet market noise reduction requirements in multi-storey living, commercial, automotive and marine markets.

Easy to cut and lay, it offers excellent support and a firm cushioned base for all types of carpet applications.

It is ideally suited for lightweight flooring constructions such as timber and marine applications where fibreglass and composite floor panels are used.

When laying carpet over a floor constructed using lightweight timber and joists, typical standard underlay offers little effect in reducing the transmission of footfall and impact noise.

Silentstep isolates the barrier layer from the floor structure, increasing the performance of the floor system between two rooms.

This feature means that critical frequencies generated during speech and electronic audio technologies such as radio and television etc can be reduced.

Double Glazing Specialist

Installing a secondary retro-fit acoustic window or door will provide significant noise reduction to your home, office or commercial application. Traditional double glazing, or refitting thicker glass, will not give you the same level of noise reduction as a secondary system.  Science explains why - it is all about the air gap! Without an air gap, optimally 100mm overall, noise cannot effectively be broken down and reduced.

Wall Soundproofing

Barrierboard is a revolutionary new material to substantially reduce noise - without breaking the bank. Barrierboard can reduce noise levels by as much as 75 per cent depending on its application. This amazing soundproofing product, is ideal for domestic, commercial and industrial sites.

Sound Absorbers

Noise reverberation is a concern in many of today's modern restaurants, gymnasiums, open plan offices and homes, sound studios, outside patios etc. where hard surfaces often prevail.

Methods of reducing this intrusive noise can be as simple as adding acoustic-absorbent panels or foam tiles to the walls and/or ceilings.
