Thermal Insulation: Avoiding Risks - A Good Practice Guide to Supporting Building Regulations Requirements

Improvements in insulation can raise problems in other areas. For example, parts of a construction remain colder, encouraging interstitial condensations, and changes in construction can lead to damp penetration. This latest BRE report explains the risks in meeting Building Regulations Approved Document L requirements for thermal insulation in roofs, walls, windows and floors. It suggests action which can be taken to reduce the risk of failure, and includes a section on the interaction between thermal insulation, ventilation and heating in the building as a whole. Each section ends with a list of quality control checks for use on site.
