U-Value Calculations

In order to demonstrate that wall constructions comply with the requirements of the Building Regulations for the conservation of Fuel and Power, namely Approved Documents L1 (dwellings) and L2 (other buildings) for England & Wales, and Technical Standards (Section 6) for Scotland, PermaRock is able to provide U-values calculated in accordance with BS EN ISO 6946: 2007 using standard data and takes into account thermal bridging effects for insulation fixings at a typical installation rate.

PermaRock also provides, alongside each U-value calculation, an assessment of condensation risk. Internal and external environmental conditions can be adjusted to meet specific building use criteria in order that accurate assessments of condensation risk can be provided, therefore tailoring the system accordingly.
