NFRC - RIBA - Pitched Roof Design Considerations: Energy, Moisture & Air Permeability

This CPD gives an overview of pitched roof design considerations and regulations in the UK and Ireland, along with discussing the type of construction membranes used as pitched roof underlays and the effect their performance has on design. It also discusses the implications of hygrothermal focused roof design on the overall building energy performance. By the end of the CPD you should have a greater understanding of:

  • Roof types outlined in BS5250:2021 Code of Practice
  • Different roof types and associated hygrothermal strategies
  • Pitched roof underlay types
  • The effects of membrane properties on design requirements
  • Factors affecting pitched roof moisture control
