This product has an Impact Noise Rating of 53dB and an Airborne Noise Rating of 47dB, provided to us by the Manufacturer.

This figure isn’t a measure of the reduction that the product gives, but is the figure that you would get following a soundproofing test and is for the floor as a whole, not this product in isolation. Please see the product specification for more details on how this was achieved.

By giving this figure it allows manufacturers to inform people like contractors, builders and architects whether or not they will pass Sound Regulations by using this product without the need to carry out a sound test.

Fitting & Installation

Karma SoundLay is an extremely versatile product; it can be bonded or loose laid, however it’s important that the mats laid acoustic foam face down. Bonding is easy if the sub-floor is clean, dry and grease free; if the SoundLay is to be placed on a timber floor ensure all floor boards are fixed in place. CMS Bond 100 should be used when bonding to the sub-floor. SoundLay should be laid in a staggered fashion butted tightly together to get the optimum effect, ensure that the mats are also tightly butted against the skirting; should you choose to remove the skirting then apply the mats flush against the wall it’s recommend that perimeter strips are installed prior to replacing the skirting boards.

Important – SoundLay can be cut to any shape or size using a simple Stanley knife.

Use in conjunction with carpets, wooden, laminate and vinyl floors

When using with a carpet the SoundLay should be bonded to the floor using the CMS Bond 100; installing carpet should be done using carpet grippers or a suitable bonding agent, however to prevent any impediments to the Soundlay performance nail gripper shouldn’t be used. Ensure that the chosen bonding agent is suitable for polyurethane materials, as shrinkage may occur.

Where a wooden, laminate or vinyl floor finish are being used, it is recommended that a stiffening layer such as a 12mm T&G Plywood layer or MDF layer is bonded to the Soundlay, using the CMS Bond 100.
