Heat loss at wall/floor junction

2017 06 22 Because of ill-health our calculation services are no longer available.

We offer a range of thermal calculation services for evaluating the energy performance of buildings, both for building regulations compliance and for design purposes, including:

  • U-values: heat loss through building elements and components.
  • Condensation risk analysis: assessing the risk of interstitial condensation within elements.
  • SAP calculations: energy efficiency calculations for new dwellings.
  • Part L1B calculations: energy efficiency calculations for extensions and refurbishment of existing dwellings.
  • Psi-value calculations: assessing heat transfer at junctions between elements.
