Chiltern Dynamics offers sound insulation testing

Chiltern Dynamics says that acoustic testing provides better results for clients targeting CSH credits.

Developers who use Robust Details as an alternative to carrying out acoustic testing may be losing out on credits under schemes like the Code for Sustainable Homes (CSH) according to Chiltern.

Acoustic testing is mandatory in England and Wales under Approved Document E (ADE).

Under the CSH, developers are awarded ratings from the lowest Level 1 to the zero carbon option, Level 6, based on a points out of 100 score across nine categories.

Chiltern Dynamics is UKAS accredited to carry out sound insulation and air tightness testing, both of which are often required prior to completion.

Barry Cope, technical co-ordinator, Chiltern Dynamics explained: "Using Robust Details is often seen as the 'safer option' as no testing is required.

Robust Details give you a tested and certified set of drawings to build to and provide a figure to use in CSH calculations.

However, this figure is often more conservative than the value the build would be able to achieve if tested, as Robust Details have to allow some contingency for lapses in build quality.

Testing, however, will often demonstrate that the individual building is at the higher end of the performance scale, so can gain more points towards a CSH rating".
