A house insulation survey is a useful service for many reasons. Sometimes homeowners are not sure why parts of their home feel cold, or they are worried about their energy usage. A thermal imaging heat loss survey can give answers to these questions and help them to prioritise what needs improving.

During a house survey, an assessor will use a thermal imaging camera to check for areas of missing or inadequate insulation in a property. These areas are visible to the camera, and are shown as hot or cold spots on a screen. The assessor will also look for the type of cavity wall and windows in the building and any gaps around them which could allow air to escape. The assessor may also inspect the loft, if accessible, and check the depth of insulation. They will also check the attic hatch and ensure it is fully insulated and the openings for items such as pipes, ducting and chimneys are sealed.

Assessing Insulation: Conducting a Comprehensive House Insulation Survey

Thermographic scanning is useful for identifying issues that are not obvious to the naked eye and can be used for new build properties as well as existing buildings. It is particularly useful in detecting areas of insulation that are wet or have fallen down which could lead to damp problems, mould growth and reduced efficiency. Thermographic scans can even be used in conjunction with a blower door to test for air leakage. This is a non-invasive and highly effective method of testing for energy efficiency, and it is recommended that all homes should have a survey undertaken by an accredited thermographer.
