INSTALLATION ADVICE

  • Roll out dB Matting across a clean and dry prepared floor
  • Bond to the subfloor with F3 Adhesive
  • Butt Joint the rolls together

Hessian-Backed Carpet Finishes, Fitted with Gripper (Domestic only)

Acoustilay perimeter strips are nailed or glued around the perimeter of the room with the barrier layer facing downwards and the acoustic seal, compressed by two thirds, to the wall or skirting board. carpet gripper rods are then nailed in place on top of the Acoustilay perimeter strip.

Acoustilay panels are tightly butted up to the perimeter detail, and loose laid in brick bond pattern onto the floor. Care should be taken to ensure that no gaps occur between the Acoustilay panels and the Acoustilay perimeter strips or between the Acoustilay panels themselves. Acoustilay 3 and 8 should be installed with the embossed black barrier mat facing upwards.

Laminate, Vinyl, Carpet Tile, Bonded Carpet Floor Finishes (Domestic and Commercial)

When installing Acoustilay beneath laminate flooring, vinyl flooring, carpet tiles, or bonded carpet, it is necessary to install Acoustilay MDF between the Acoustilay and the floor finish.The use of Acoustilay MDF improves stability for the floor finish and prevents problems due to point loading, carpet rucking and joint damage to the floor finish. In the case of bonded carpet and carpet tile floor finishes, the use of Acoustilay MDF will also aid the installation by giving a stable surface to bond to.

Acoustilay should be bonded to the sub-floor in brick bond pattern using SRS Acoustilay adhesive. Acoustilay 3 and 8 should be installed with the embossed black barrier mat facing upwards. Care should be taken that Acoustilay panels are butted tight against the perimeter wall or skirting and that no gaps occur between the Acoustilay panels themselves. Acoustilay MDF should then be bonded to the top of Acoustilay with SRS Acoustilay adhesive.

The Acoustilay MDF boards should be bonded to each other using a PVA adhesive on the T&G joint and any such joint should be a minimum of 50mm away from any Acoustilay joint. An isolation gap of 5-10mm should be left between the wall and the Acoustilay MDF to avoid sound transmission flanking into the structure.

The isolation gap should be filled with SRS acoustic sealant.The floor finish should then be installed on top of the Acoustilay MDF as per the manufacturer’s instructions. In areas where the floor covering is returned, a timber fillet, the same thickness as the Acoustilay, should be placed around the perimeter to create a solid edge.

Please note that timber based products are prone to expansion and contraction, as such SRS recommend that expansion gaps are introduced across the Acoustilay MDF, as well as at the edges, in large applications. Further details on expansion gaps can be found at the timber research and development association website: www.trada.co.uk.

If you have a large area to treat with Acoustilay MDF, SRS recommend that you contact Trada for advice.

Engineered Timber Floor Finishes (Domestic)

In our experience, there is no issue installing Acoustilay 8 or 15 directly beneath engineered timber floors in domestic installations. The Acoustilay should be installed as described in the ‘Hessian backed carpet finishes, fitted with gripper’ section, but without the perimeter strip detail.

The Acoustilay should be butted tight up to the wall or skirting. As with all floating floor installations, no fixings should be allowed to penetrate the Acoustilay and an expansion gap should be allowed between the timber floor and the perimeter wall and services. This should be filled with SRS acoustic sealant or alternative flexible sealer.

For confirmation on the suitability of any engineered timber floor for use with Acoustilay, please check with the floor finish manufacturer prior to installation. If the floor manufacturer feels that the resilience of the Acoustilay is excessive, or if the installation occurs anywhere other than a domestic environment, SRS recommend that the timber floor should be supported by installing a layer of Acoustilay MDF, bonded to the top of the
Acoustilay. In this situation the full instructions of the ‘laminate, vinyl, carpet tile, bonded carpet floor finishes’ section should be followed.

If required, SRS will be happy to provide samples to the engineered timber floor manufacturer for test purposes. The density of the open-cell resilient layer in all the Acoustilay products is 135kg/m3.

Stairs (Domestic, Hessian-Backed Carpet Finishes)

Acoustilay 3 (impact sound insulation) – Acoustilay 3 should be installed with black barrier mat facing upwards. panels should be cut to size and bonded to tread using SRS Acoustilay adhesive. Acoustilay 3 can be formed around the nosing of the stair, as with conventional underlay, if required.

Acoustilay 8 and 15 (impact and airborne sound insulation) – Acoustilay 8 should be installed with black barrier mat facing upwards. Acoustilay 8 and 15 must be installed with Acoustilay perimeter strips. The perimeter strip is nailed to the tread or riser as displayed in the diagram.

Acoustilay panels should be cut to size and bonded to tread and riser using SRS Acoustilay adhesive. For the nosing detail, a fillet of MDF, the same thickness as the Acoustilay should be installed beneath the nosing to ensure a uniform height.

Fixtures & Fittings

When installing Acoustilay it is important not to fix directly through the product into the sub-floor due to the risk of sound bridging.

When items such as kitchen or bathroom units need to be securely fixed to the floor they should first be mounted and fixed onto an MDF plinth to the same height as the Acoustilay being used. Ideally, the plinth will cover the footprint of the item and the Acoustilay can then be butted up to the MDF, maintaining a consistent floor level and providing secure fixing points. In the case of fitted cupboards and wardrobes, Acoustilay should be used to treat floors inside the cupboard to prevent flanking of airborne sound.
