Product Summary - A Laminate Floor Solution

The Isosonic mat is a cost effective means of achieving soundproofing against impact sound.


Under Laminate floors to greatly reduce impact sound (20db plus)

Under an engineered floor to create a low impact floating floor

Under Screed to reduce impact sound on a concrete floor

The Isosonic mat is a very versatile product which can used with a number of overlays , its is excellent at reducing impact sound while maintaining a firm non spongy feel to the floor. (This spongy feel is a frequent complaint amongst users of other rubber mat treatments.) It is our view that the decibel rating quoted by many thinner 3mm underlay's is dramatically overstated and their performance is significantly inferior to the Isosonic mat when tested in real world situations ( as apposed to lab test conditions)

When used in conjunction with our Tecsound 50 or Tecsound 70 acoustic membrane the combination can provide a very meaningful improvement in airborne and impact sound for newly laid laminate and engineered floors. The Tecsound 70 is a 3.5mm mat as opposed to the 2.6mm Tecsound 50. The extra mass of the Tecsound 70 should add around 4 Db more acoustic protection in comparison to the tecsound . Customers wishing for further airborne soundproofing can also add mineral beneath the floors boards. Remember with all underlay rubber mats the improvement quoted is only an impact sound improvement and that they will have very little airborne sound transmission qualities.


Isosonic mat and regulation E

When used in conjunction with a hanger ceiling ( isosonic hanger) it will achieve in excess of the requirements laid down in regulation E.
The product can be turned up at the perimeter of a chipboard floor to create an integral flanking band.


Isosonic mat is made with recycled waste rubber, dense and tough it lays flat. It is easy to cut and lay. It is not easy to dislodge or damage during screeding.

Isosonic Mat

A versatile and cost effective method of significantly reducing impact problems associated with laminate floors.

The Isosonic mat is a high quality cost effective method of reducing impact sound beneath laminates and structured engineered floors. It can also be used as a method of improving the impact qualities of any carpeted floor acting as an impact resisting layer to go under existing carpet underlay. This versatile product can also be laid under screed to isolate a cement sub floor . So reducing the impact sound associated with solid cement floors.

We are regularly asked by householders about replacing carpet with laminates in their properties. The question is often whether the use of the isosonic mat underneath laminates will "be as good as carpet" as often specified in building leases. There is no simple answer to this, as the quality of the original carpet, its underlay and sub-floor all have a bearing on how the original carpeted floor is performing. Some carpets will perform well, and others badly from an impact sound perspective. Where a poor carpet is in place, the isosonic matt and laminate might out perform the existing carpet. The isosonic mat truly transforms the acoustic qualities of a laminate floor and improves internal room acoustics as well.

The key difference with this and many other mats on the market is its relative firmness. This means that is ideal to go under products such as laminates or engineered floors without creating too spongy a feel. It is also very cost effective compared to many other impact mats on offer. It remains the number one choice for those laying laminate floor but wishing to deaden the impact sound they are generating to neighbours below.

In applications where it is laid under laminate floors it also improves the internal room acoustics, softening the general noise levels generated in the room. For this reason it is one of our top sellers as a superior laminate underlay.

If you are also looking to improve the airborne (TV and talking ) sound soundproofing between rooms, (say between two flats) then adding a layer of Tecsound 50 is and excellent choice.

NOTE: where noise from below is your problem you should be concentrating on getting the maximum arirborne uplift you can. Rubber mats vastly improve impact sound reduction ( benefiting downstairs neighbors they are not as good at reducing the sound coming up, hence our recommendation for Tecsound).

Isosonic Mat- Fitting

This is a very simple product to fit. Simply cut to size of the room, where possible avoiding gaps and spaces. The new laminate engineered floor is simply laid over the floor and fitted as normal. If laying this type of floor there is no need to add any further type of underlay. The Isosonic mat is not normally glued to the sub floor, as it lies in place under its own weight. Where the need to glue is specified then isobond adhesive can be used or any other water based acrylic glue. Please note that solvent based adhesives should not be used.

Where it is being laid under carpet a carpet underlay should also be added (for comfort)

The mat can be turned up at the perimeter of the room if required to act as an integral flanking ban and excess trimmed off. This is normally only necessary where a chipboard floor is being laid over and high traffic is expected.

The Isosonic mat has very little thermal resistance so underfloor heating can be present in contact with it either above or below.

Best practice when using underfloor heating is to have a layer of PIR insulation ( i.e. Celotex - at least 20mm thick) overlaying the Isosonic mat and then the underfloor heating. This will reduce any heat loss downwards.

What do these dB numbers mean in real terms

What do these dB Figures mean in practical terms? In simple terms a 10dB improvement equates to a 50% reduction in sound you hear, 20db equates to 75% AND 30dB TO 87.5%. However this is not the same for all frequencies. This is just an average performance across all frequencies, and higher frequencies will perform better than lower. Learn More. Note that Isosonic when laid under laminate is superior to most laminate underlay's on the market which are 4mm thick. The performance of the mat on a like for like basis with laminates is superior in all impact tests and at all frequencies. Boasting an in isolation figure of around 38dB. The figure we state is real performance uplift when under a laminate floor ( 20dB+)

Comparing our products with others:

Please note that the figures that we provide refer to improvement over the average floor as opposed to the performance data of the product in isolation.By this we refer to products that can be lab tested in a way that the product is tested on its own, which can give little indication how it performs in situ,(i.e. on your floor)

This is a very important distinction to understand and is confusing to a lot of people. Almost all our competitors will state the performance of the product either in isolation or include the existing floor construction within their numbers. This will exaggerate the true benefit of their products. For more information click here. This is particularly the case with laminate underlay's.

A Key to the table terms above? We compare the following key issues.

1) Floor height gain - How much floor height will rise as a result of soundproofing
2) Labour intensity - How long will the job take? In general lifting all the floor boards will add dramatically to the time required to complete the soundproofing you can think of lifting 3 of 5 boards ( see on line instructions for further details)
3) Typical Airborne uplift - This gives you an idea about how much airborne sound your stopping coming up from below ( or from above) TV / Talking that kind of thing. The bigger the number displayed the better the performance. THIS IS THE KEY THING to worry about if your soundproofing from neighbour noise downstairs
4) Typical Impact Uplift - This gives you an idea about how much impact ( footfall) sound your stopping going downstairs. The bigger the number displayed the better the performance. Again this is only important to you if your neighbours are concerned about your footfall.
