Installation

The mats can be laid in a brick bond formation, staggering the joints reduce sound transmission along the edges. If you are installing the NSSF7+ with perimeter strips these should be installed before the mats. The NSSF7+ is laid inside the perimeter strips, or butted up to the skirting board if you are not using the strips. The mats can be cut with a sharp knife such as a Stanley knife.

Each sheet is 1200mm x 600mm so is easy to handle. Needs to be installed with no gaps between the sheets and the joints staggered. You can bond them to the floor or lay them loose. The edges can be tightly pushed into the edges of the room as sound does not vibrate along the sheets.

Carpets- If carpet grippers are required we would recommend the use of the perimetre strips around the edge of the room to ensure the finished floor height is the same. Fix the strips around the edge of the room then lay the NSSF7+ product inside the perimetre strips. Attach carpet gripper rods to the strips and then lay the carpet as normal. if you are not using carpet grippers lay the NSSF7+ up to the skirting.

Laminate or wooden floors- We recommend that a 9mm layer of ply wood or equivalent be bonded on top of the NSSF7+ before laying these floor finishes. This should be checked with the installer of the flooring materials.

NSSF7+ can help to conform to Building Regulations (Approved Document E) offering improved levels of impact and airborne sound insulation, when used on an existing timber floor.
