Floor Solution 5

5a Absorbalay-High Mass Rubber mat

ABSORBALY MAT £27.95- 1.2m x 1.0m - 18kg per mat.

A very DIY-able solution that improves the performance of your floor quickly and easily.

Absorbalay 15

If you wish to improve the soundproofing of your floor, with particular reference to impact sound then the use of Absorbalay mats is a good choice. Absorbalay 15 ( 15mm thick) which is designed to reduce impact and airborne sound . From an impact sound perspective this an excellent product and delivers very good results in high traffic areas such as hallways and stairs.

Of the range of foam core heavy mats on the market Absorbalay stands out as excellent value boasting a very stable crush resistant core as well as the benefits of high mass.

The Absorbalay 15 mat weighs 15kg /m2 ( and is directly comparable with Acoustilay and NSSF7 mats in performance terms) it acts to reduce airborne sound by increasing floor mass and resilience (springiness). In addition, by sealing the gaps in the floorboards as well you are bringing into play the wooden floor which acts as a reasonable soundproofing surface when all the gaps are sealed.

The soundproofing of airborne sound if an issue can be further improved with the use of Tecsound 50 an acousitc membrane. If using carpets make sure any adhesive you use is suitable for polyurethane materials. If applying laminate or vinyl as your final walking surface an extra layer of 6mm ply can be added to prevent the floor feeling spongy.
For customers looking to insulate noisy pipes please see our acoustic pipe wrap.

Solution 5a


Solution 5b




In addition to the acoustic performance it is vital to assess the "crush ability" of any mat based products,as this will have implications on it performance at higher load ( i.e. running children) . Many mats will perform reasonably in a test environment but come up short in a real world situation. In terms of "crush ability". the absorbalay we believe is best in class. This also means it is more suitable for customers who are looking to add a floating floor to the surface.

We have compared other rubber mats in the market comparing price and performance. Aside from the mass of the mat which is 15kg/m2 ( an industry standard) we also looked at a crush test. Specifically this measures the performance of the foam core. Absorbalay came out top in this test. A soft core can point to a lower performance product that will be less suitable under wooden floors.

This test puts the product ahead of the competition when using as a impact sound reducing method particularly under wooden floors.

Important Note*

As a consumer comparing different products from different companies is very hard.
While we talk about improvement in decibels in all our tables many other companies will state a single figure for their products which is often in excess of 40 or even 50db. It is really important to understand that these figures invariably refer to the performance of a whole floor ceiling structure, and this will include a standardised floor and ceiling that will already be quite well soundproofed. There is no single product in existence, to our knowledge that will provide in excess of 30 db when added to a standard floor ceiling divide ( plasterboard ceiling and wooden floor).
In an attempt to level the playing field we are taking a standard ceiling 12mm plasterboard a void and 18 mm floor boards as our base case. We reckon that this has an acoustic performance of about 34 db rw ( airborne). The final column of our table gives an indication of we believe our system might achieve in Rw( simple airborne performance) terms.
An important word about regulation E ( the sound test required for conversions) . We have a dedicated regulation E web site www.uksoundproofing.co.uk. The figures in the above tables do not take into account Ctr corrections so do not attempt to create an off the shelf solution for regulation E

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

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.
