Thermal imaging

Find out where your home is leaking heat

What is thermal imaging?

Thermal imaging can vividly reveal where your home is leaking heat.    The cameras are sensitive to infra-red and make ‘temperature map’ images .    This can show problems with insulation, draughts, damp and more –  useful in older homes, but also for revealing defects in new-builds. The images are easiest to decipher when it’s at least 10°C warmer inside than out, so this is mainly a winter activity.

Some of the problems shown are easy for householders to fix, like draught-proofing, and some, like faulty insulation, may need professional help. Significant improvements in comfort, energy bills and carbon emissions are often made as a result. More in this 2-page report.
