Recognised Construction Details ™ (RCD) provides energy assessors, builders, architects and other designers with a suite of independently assessed thermal junction details that have been certified for use in demonstrating compliance with Part L of the Building Regulations.
The 2021 update to Part L and the move towards the governments Future Homes Standard has increased the focus on heat loss through thermal bridges in new homes.
Work by the Future Homes Hub goes further and has reported that it is no longer possible to comply with Part L without the use of calculated Ψ values.
Part L defines two methods to assess thermal bridges; individually modelled values or using a database of independently assessed details such as Recognised Construction Details ™ (RCD).
