Condensation risk analyses are carried out using the method in BS EN ISO 13788 2002 (and BS5250 Appendix D). U-values are calculated taking into account repeating thermal bridges using the methods in ISO 6946 (walls and roofs) and ISO 13370 (ground floors) to help you demonstrate compliance with the Building Regulations and Building Standards.
