Adhering Sonaslat panels directly to the wall:

By far the quickest method to install Sonaslat directly to a wall is with Sonatac adhesive. The is should be applied to the rear of the panel using a sealant gun. Typically, 2no 300ml tubes of Sonatac are required per panel of Sonaslat. Once applied, the Sonaslat panel can then be offered up to the wall and pressure applied until the adhesive ‘grabs’ the panel and it holds in position. The adhesive should fully cure within 24 hours.

Screw fixing Sonaslat panels directly to the wall: To mechanically fix Sonaslat to walls and partitions SRS recommend using black screws fixed through the acoustic felt part of the product, into the wall behind. SRS recommend fixings at 200mm intervals across the width of the panel and 800mm intervals down the length of the panel, giving a total of 12no screws per Sonaslat panel.

Screw fixing Sonaslat panels onto timber battens:

Class A acoustic absorption performance can be achieved by using Maxi Slab 50 mineral wool and timber battens behind Sonaslat panels. The recommended method of installation is to secure 50x50mm timber battens at 600mm centres horizontally across the wall using appropriate fixings.

Appropriate fixings that suit the construction being fixed to should be used, depending on whether it is plasterboard or masonry. During installation always rember to wear appropriate PPE and, if drilling into the wall, always check for electrical wires before commencing.
