Product Summary

Soundstop 6mm Ceramic acoustic underlay is a cork composite product designed to provide impact sound insulation under ceramic floors, but also under laminate, engineered wood floors, certain vinyls, and linoleum. It is manufactured from totally recycled cork and rubber granules bound together to form an acoustic sheet which delivers resilience and durability. The product has been tested and reports a reduction in impact noise of 19dB under ceramic flooring.

The product is ideal for residential and commercial installations where a high performance acoustic underlay is required at a relatively light weight and low cost. At 6mm, it offers excellent acoustic performance at this relatively low thickness, the natural honeycomb structure of the recycled cork added to the durability and resilience of the rubber crumb helps to deliver the high all round performance. It also has a low Tog rating making it ideal for underfloor heating installations.

When used in conjunction with our Tecsound 50 or 70 acoustic membrane the combination can provide a very meaningful improvement in airborne and impact sound for newly laid 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 50. Customers wishing for further airborne soundproofing can also add acoustic mineral wool beneath the floors boards. Remember that with all underlay rubber mats the improvement quoted is only an impact sound improvement and that they will have very little airborne sound reduction qualities.

Product Application

Our 6mm acoustic mat is a versatile and cost effective method of significantly reducing impact problems associated with ceramic floors.

The mat is a high quality and cost effective method of reducing impact sound beneath ceramic 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.

If you are also looking to improve the airborne (TV and talking ) soundproofing between rooms, (say between two flats) then adding a layer of Tecsound 50 or Tecsound 70 is an excellent choice.

NOTE: where noise from below is your problem you should be concentrating on getting the maximum airborne uplift you can. Acoustic mats vastly improve impact sound reduction (benefitting downstairs neighbours) they are not as good at reducing the sound coming up, hence our recommendation for Tecsound and acoustic mineral wool).



Instructions for use

Installation - General

The acoustic mat must be bonded to the subfloor. It is not essential to commence installation in the centre of the room; it is generally more practical to commence along the longest wall running the rolls in parallel. Wherever possible the product should be installed so that the joints run with the direction of the main light in the installation area rather than against it. Ideally this will also be at 90 degrees to the finished floor so that the chance of coinciding joints is minimised. The product should be dry laid into workable areas and cut at least 50mm over the length required and allowed to relax for the acclimatisation period as advised above.

After acclimatisation the underlay should then be cut using a utility knife and straight edge and a gap of around 3mm should be left around the perimeter to allow for any expansion. The product should not be in direct contact with any wall, column or skirting board that has not been isolated using a perimeter isolation strip.

The product should be adhered to the subfloor using a recommended adhesive strictly in accordance with the installation instructions of the adhesive manufacturer. It is particularly important to refer to the adhesive manufacturer’s advice in respect of trowel sizes, application rates/coverages and open times.

Only spread enough adhesive to cover a workable area, and after the required open time lay the mat into the adhesive and smooth out from the centre using a carpet glider or hand roller to ensure that the product is fully into the adhesive and all air bubbles are released.
The product should then be fully rolled into the adhesive using a 68kg articulated flooring roller to ensure full adhesion along the entire length and width of the product.

All edges should be butt jointed ensuring that all seams and joints are smooth without any voids but not too tight.

Installation – Ceramic

Once the product is fully bonded to the subfloor, this time will depend on the adhesive used but usually after 24 hours, the ceramic tiles can be installed.
To provide noise improvement the acoustic mat has to have a level of resilience to absorb impact energy and as such adds a degree of softness to the overall floor. This must be born in mind and suitable flexible adhesives and grouts for the installation of ceramic floor tiles onto resilient subfloor must be used.

Installation of the ceramic tiles should be carried out by suitably trained and qualified installers experienced in this specific type of installation and using the appropriate tools and equipment. Always refer to and follow the specific installation instructions of the ceramic floor tile manufacturer for installation onto a resilient subfloor.

The mat has very little thermal resistance so can be used alongside underfloor heating, it can be installed either above or below the UFH. Best practice when using underfloor heating is to have a layer of PIR insulation, such as Celotex, at least 20mm thick, then overlaying it with the mat and then the underfloor heating. This will reduce any heat loss downwards.
