Acoustic absorbers – specifying acoustic absorbers where they will be installed against a wall
This advice note will help specifiers understand the performance (including fire) of wall mounted acoustic absorbers, acoustics and room acoustics, reverberation and absorption, conformity marking and importantly their installation.
Benchmarks – why are they so important
Benchmarks are used to establish a standard that future work can be judged against. For example; benchmarking something for the quality of finish or technical execution, and to set a level for what’s expected throughout a project. This guidance looks at the best way to use benchmarks and what to do if they are not part of a contract or included in the specification.

Third party certification varies according to the terms of each scheme, but essentially includes verification of the test evidence and scope of application or use of the product, and a regular audit of the factory quality assurance system.
Fire stopping – mouse holes
Small holes, sometimes known as mouse holes occur as a consequence of deflection heads on some systems at high level between the back of the wall channel and the above the face plasterboard on corners and three-way junctions. This technical note has been produced to help inform your site teams and designers of the responsibility to ensure that they are fire stopped and that the designer has approved the detail.
