Thermal imaging of building fabric
Thermal imaging is a quick and visually effective way to identify air leakage and insulation defectsBSRIA offers thermal imaging of building fabric to identify where air leaks in or out of buildings and show thermal insulation defects. Its main benefits are:
- quick, non-disruptive inspection
- results easily shown in pictures
- resolve arguments with sub contractors as to where faults are
- can be used to show the effectiveness of heating and cooling installations
The thermal image, which is effectively a picture of thousands of surface temperature measurements, makes it easy to see where insulation is missing or air is leaking in or out of a building.
Any object that is not generating or absorbing heat will tend towards the surrounding air temperature, so cold air leaking into a building will show as cold patches on the wall, floor or ceiling. Conversely, warm air leaking from a building will cause warm patches on the outside wall or roof. Thermographic testing alone can be used as a quick method of finding air leaks in a building structure, and can be used alongside airtightness testing which will quantify the leaks.
