Constructive Details (CDL) is the result of a new joint venture between The British Board of Agrément (BBA) and Robust Details (RDL). The venture aims to provide solutions for the linear thermal bridging requirements brought about by Building Regulations Part L.
The BBA is the UK’s leading authority for approval, inspection, testing and certification to manufacturers and installers in the construction industry. The RDL Certification Scheme assists accreditation for walls and floors in joined homes. Together they hope to tackle the complicated issue of linear thermal bridging, which can be accountable for up to 30% of heat loss in a building. The launch of a new handbook specifying the masonry detail junctions developed for the Aircrete Products Association brings together RDL’s expertise from Part E of Robust Details and BBA’s technical competency scheme experience, amongst other contributions.
The CDL believes the scheme can benefit participants in reducing the use of conventional insulation, fulfilling Part L requirements and the use of reliable and beneficial ψ-value(s) of junctions to be used in SAP and SBEM calculations.
