BSRIA has updated the Thermal Imaging of Building Fabric guide in the light of new updates to building regulations, advances in camera technology and improved methods of analysing images.
The guide replaces the previous edition (TN09/2002) and aims to help people involved in constructing, owning and operating buildings with obtaining the thermal imaging they need and gaining an understanding of the information that can be obtained.

Thermal imaging produces a picture that maps the amount of infrared radiation across the field of view and this can be converted to a map of apparent temperature based on a number of assumptions explained in the guide.

Thermal imaging is the best way to assess continuity of insulation or locate air leakage paths in a completed building. This helps project teams comply with the Building Regulations, specifically Part L that requires provision be made to avoid heat loss through the building fabric. BREEAM credits are awarded for thermal imaging surveys of new buildings providing defects are addressed.

This guide is referenced by the National Building Specification, the Technology Strategy Board, and the British Institute for Non-Destructive Testing's PCN scheme.

Contents include:
· The need for thermal imaging
· Thermal performance of buildings
· What to expect from a thermographic survey
· How to choose a thermographer
· Different approaches to the survey
· How to interpret the results
· Supplementary testing
· Expected report contents

The guide will shortly be available to order at £20 full price or £10 to BSRIA members. Free pdf versions of the guide can also be downloaded via the BSRIA website.
