TRADA has published details about how timber frame manufacturers can meet future revisions of Building Regulations Part L with mineral wool and rigid foam insulation.
The new volumes build on standard details published during the summer to prepare for higher thermal performance demanded by the October revision of Part L.
“The standard details were always intended to be a ‘starter for 10’ to enable manufacturers and designers to meet the new Part L requirements,” said TRADA’s Lewis Taylor.
“But we know that the 2013 revision will further ramp up performance. The new optimised details have been produced, therefore, working closely with industry, as a way of gently predicting what will happen tomorrow, giving better airtightness and further reducing thermal bridging.”
Improved thermal details included are 50mm-deep insulated service voids created by fixing battens to the inside face of the 140mm studs, plus improved insulation in party walls.
Twenty critical details that arise in timber frame construction are identified.
