  • The premier acoustic underlay to reduce impact noise

  • Superb airborne noise reduction too

  • Only 15mm thick and fully DIYable solution

Absorbalay 15mm is a premium acoustic underlay designed to combat both airborne and impact sound.

Our highest performing soundproof underlay, equivalent to Acoustilay 15, is ideal for both new build and refurbishment timber and concrete floors. It provides excellent soundproofing under carpets, laminates, vinyl, and engineered wood floors.

 

Absorbalay 15 is the perfect solution if you are looking for the very best in impact resistance, along with excellent airborne performance, and in only 15mm of additional height. It is also straight forward for a competent DIYer to install themselves.

Absorbalay is made of a bespoke closed-cell polymer layer, sandwiched between two sheets of high-mass acoustic barrier. This not only provides both impact and airborne protection, but also provides insulation across a much wider range of frequencies.

Need help calculating how many boards you need? Have a look at our Absorbalay Solution Calculator which will walk you through what you need, and show potential upgrades which can enhance the performance of the system even further.

Absorbalay can be used as part of a regulation E compliant system, in conjunction with an approved ceiling solution (we can help you with that too!). We know you will discover that this is the most impressive mat on the market, so please call us on 0208 123 9710, or email us, if you would like to request a sample.


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.

As you can see from the test result below, Absorbalay performs very favourably against competing products, in the above system:

Impact (L'ntW) = 47dB

Airborne (DnTw) = 61dB

See our guide to what these numbers mean!

Notes on fitting a carpet over this product:

The mat should run wall to wall with few or no gaps at the perimeter. Any gaps should be sealed with acoustic sealant. This will maximise the airborne acoustic performance achievable from using the mat.

There are a couple of options available to you should you wish to fit carpet on top of Absorbalay:

  • If the carpet is an existing pre-stretched carpet ( i.e. it has been down for a while ) then you can refit the carpet back to the mat with double sided carpet tape, available in DIY or carpet shops.
  • If the carpet needs to be laid with gripper rods there are two options:
    1. Create a raised surface around the perimeter of the room onto which to place the carpet gripper. This can be either screwing directly onto the old carpet gripper or introducing a slim 15mm batten around the perimeter of the room and running the mat right up to the batten. The grippers would then be screwed onto the batten. The carpet then fitted in the normal way.
    2. Create a raised surface around the perimeter of the room onto which to place the carpet gripper. This can be either screwing directly onto the old carpet gripper or introducing a slim 15mm batten around the perimeter of the room and running the mat right up to the batten. The grippers would then be screwed onto the batten. The carpet then fitted in the normal way.

For customers wishing to add a 6mm ply surface. We can recommend a vinyl type adhesive such as Bostick Laybond Vinyl. The adhesive should be high tack and solvent free. Occasionally customers have found they need to prime their 6mm ply with a diluted solution of PVA.
