Sound insulation performance above the Building Regulations was eligible for credits available under the Code for Sustainable Homes (CfSH); although the CfSH has been scrapped, it is widely acknowledged that achieving the minimum sound insulation performance legally permissible may not make for the most sustainable dwellings, as some occupants will be dissatisfied with the acoustic conditions. Up to four credits were available by increasing the sound insulation between dwellings above current standards. Apex can advise on wall and floor types and associated flanking details to achieve the additional credits in timber frame, masonry or modern methods of construction (MMC).
As a UKAS-accredited laboratory, we are deemed to be a Compliant Test Body as required for CfSH credits on completion.
Following the government’s Housing Standards Review in 2014, the Building Research Establishment (BRE) has established the Home Quality Mark to fill the gap left by the CfSH; this will have credits for acoustic performance, and Apex is contributing to establishing the standards.
Apex is committed to researching and advising on the acoustic issues which affect the sustainability of buildings, including noise from mechanical ventilation systems, the interdependence of overheating and acoustic conditions, and the sound insulation performance of different construction methods and details.
