SoundLay - Z400
SoundLay is designed for concrete floor applications and can also be used for timber floors. It is primarily used where impact noise insulation is required although can also provide a level of airborne noise insulation.
It is a two layer laminate, the upper being CMS WB7.5 acoustic barrier supported by a 6mm layer of CMS Class 0 acoustic foam.
SoundLay Plus - Z400-P
SoundLay Plus is primarily designed for timber floors although can also be used with concrete floor constructions. It offers additional airborne and impact sound insulation to SoundLay so is aimed at developments where superior noise control is necessary.
This high performance composite is a sandwich laminate of two layers of CMS WB7.5 acoustic barrier separated by a 6mm layer of CMS Class 0 acoustic foam.

Installation
CMS SoundLay acoustic underlay is supplied in standard sheet/tile sizes. These are easy to lay on the floor in a staggered pattern, placing tightly together.
The SoundLay sheets can be laid loose or bonded to the floor. When bonding to the floor, ensure that the surface is clean, dry, grease free and that the flooring is secured before bonding. CMS Bond 100 should be used. The SoundLay sheets can be pushed up to the skirting board or wall; ensure a tight fit to prevent flanking of airborne noise.
Carpets
Can be installed using grippers or by bonding. Contact CMS Danskin for advice on the selection and fitting of grippers. When bonding, ensure the adhesive is suitable for polyurethane materials, as shrinkage may occur. When bonding carpet, it is recommended that SoundLay sheets are first bonded to the floor, using CMS Bond 100.
Laminate*
Where a wooden laminated floor finish is being used, it is recommended that a layer of 12mm T+G plywood or MDF is bonded to the SoundLay first, using CMS Bond 100.
Vinyl
Where vinyl floor coverings are to be used, it is recommended that a layer of 12mm T+G plywood or MDF is bonded to the SoundLay first, using CMS Bond 100.
Recommended Adhesive
For bonding to the subfloor, CMS Danskin recommends the use of CMS Bond 100.
*Please note, nail bound systems must not be used with SoundLay as this will compromise the material’s acoustic performance.
