Constructive Details Ltd handbook
The British Board of Agrement (BBA) and RDL have joined forces to form a joint venture called Constructive Details Limited.
Under this initiative the two companies aim to work together with the industry to provide solutions on the increasingly complicated, technical and often confusing issue of linear thermal bridging.
Linear thermal bridging (described by a psi-value) can now account for up to 30% of heat loss in a building.
with the need to provide more energy efficient buildings on the road to zero carbon, the industry is looking for ways to obtain reliable, favourable and realistic psi-values.
One of the aims by CDL is to facilitate accurate psi-value calculations.
To achieve this, the first Constructive Details handbook of masonry detail junctions developed for the Aircrete Products Association has been launched.
The Handbook is available electronically via a dedicated Resources page on the CDL website and can be downloaded free of charge.
As Greg Cooper, Chief Executive of the BBA, said: “The BBA is delighted to have worked in partnership with RDL to produce this handbook.
“It will undoubtedly enable aircrete block manufacturers to pass on accurate information to their customers and provide house builders with a complete list of thermal details to use in their design and build process”.
Dave Baker, Chief Executive of RDL, added: “The CDL handbook follows the principles of the Robust Details Part E scheme handbook and should prove to be an invaluable tool for designers and new home builders alike.”
Significant investment in equipment and personnel has been made by the BBA regarding the testing of External Wall Insulation/ETICS (External thermal insulation composite systems) in accordance with European Technical Approval Guideline (ETAG) 004. The company’s hygrothermal rig is UKAS accredited and tests the performance of EWI systems by putting them through a series of extreme temperature cycles.
Department for Communities and Local Government (DCLG) has approved the BBA application to operate a competent person self-certification (CPS) scheme for the installation of solid wall insulation, including internal, external and hybrid insulation systems. The BBA already have a number Agrément Certificates for solid wall insulation systems and means installers can self-certify that their work complies with Building Regulations.
Robert E Lee, now approved to carry out external wall insulation projects, becomes the 200th installer to be approved by the BBA to the requirements of PAS 2030 for the installating energy efficiency measures in existing buildings.
Jan - March 2013: Agrément Certificates, BFRC Certificates and Certificates issued against the requirements of the Microgeneration Certification Scheme (MCS) awarded by the BBA.
As a notified certification body and notified laboratory, the British Board of Agrement (BBA) helps in identifying relevant standards and can carry out many of the tasks associated with CE marking.
