Why Absorbalay Mats

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 is a high performance 15mm mat 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.

How it works

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.

Please note that the acoustic sealant for this solution comes in 900ml tubes. If you require a jumbo gun, the please let us know, and we can add one to your order.

For more detailed installation instructions view the Absorbalay Floor Instructions.

Crush Testing

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 its 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.

Best in Test

Best in Test

We have compared other rubber mats in the market by 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.

Feel free to request a sample.

Upgrade options

The soundproofing of airborne sound, if an issue, can be even further improved with the use of a Tecsound acoustic 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.

Tecsound Acoustic Membrane Upgrade

Upgrade your soundproofing solution with the Tecsound acoustic membrane, which delivers an impressive performance boost. It is extremely flexible and improves both airborne and impact passage of sound.

It is a high density, polymer based synthetic soundproofing membrane providing excellent acoustic insulation in different construction elements. It is very flexible and very easy to use, an therefore has numerous applications, whilst also being self extinguishing and fire resistant.

Using an Under Floor Heating System?

You will need to ensure that all the soundproofing products are suitable for use with your specific system as performance differs between them. The Tecsound Acoustic Membrane has a thermal conductivity figure of 0.45 W/mK, please check it’s ok for use with your specific Under Floor Heating system before proceeding.

Tecsound Performance

Tecsound Performance

The performance of the Tecsound Membranes is truly impressive. In fact, it's performance is equivalent to lead of the same surface weight. The Tecsound 50 in a single layer boasts an Rw figure of over 25dB and due its chemical make up it has exceptional damping qualities.

It is these qualities that are normally absent from rigid plasterboard type constructions. This resilience means that it compares very favourably to the likes of green glue, as it not only provides great resilience but it also provides high mass. The membrane has reinforcing scrim on one side and when applying the panels it should be facing you.

More information.....

When it comes to soundproofing your floor, it is important to establish what you are trying to achieve. Are you trying to stop noise from below reaching you, or are you trying to eradicate your impact noise passing down to your neighbours?

In practice, most people are aiming at stopping the sounds from below traveling upwards. Many products on the market boast great soundproofing credentials (particularly rubber mat or underlay solutions) but the figures quoted are almost always referring to a reduction in impact sound and are of very little use in identifying how much airborne sound is being reduced.

The total performance which is normally quoted on most sites refers impact sound only. However if you are worried about sound rising from below you should only consider the airborne sound number (which is rarely quoted).

We also give an indication of acoustic performance uplift. Remember that every 10dB of performance uplift corresponds to roughly a 50% improvement in the performance of the floor. So 20dB would indicate a 75% Improvement over and above the original floor.

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.

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. This is particularly the case with laminate underlays.

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 40 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 case study. We believe 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 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.
