Installing Noisestop Acoustic Underlay
Noisestop Acoustic Underlay
Installation of acoustic underlays can be carried out by anybody that feels they are a competent DIYer. If you don’t want to install the products yourself we would normally recommend a local carpet fitter, if you are already replacing your floors as part of the work your floor fitting company would be able to install your soundproof underlay.
Soundproof underlay can be loose laid over the existing floor, there is no requirement to glue the flooring in place unless the installation is for Part E in which case a floor grade adhesive should be used as stipulated in the 2003 regulations.
Laying a carpet over Noisestop Acoustic Underlay
If you are using Noisestop Acoustic Underlay below carpets you should consider whether to use a traditional carpet underlay or not. Gripper rods should be used around the perimeter of the room to hold the carpet in place. If you are going to use the Noisestop Acoustic Underlay with an underlay you should install the perimeter edging strips before the carpet grippers. Secure the edging strips and grippers with tacks or nails.
Installing solid floor finishes over Noisestop Acoustic Underlay
Flooring that is less than 15mm thick should be combined with a 6mm ply or MDF sheet to ensure there is no movement of the finished floor. Laminate flooring, engineered flooring should be bonded to the ply or MDF. Flooring that is thicker than 15mm can be laid directly over the mats. Consideration should be given to the possibility of sound transferring from the solid flooring to the walls, use isolation tapes against the wall to prevent flanking noise.
