All surfaces above 0 degK (-273 degC) emit infrared radiation invisible to the naked eye. The intensity of infrared radiation emitted depends on the surface's temperature. A Thermal Imaging camera detects this emitted radiation and transforms it into a visual infrared picture, or thermogram, viewable on the screen. The resolution and therefore the ability of the camera to pick up minute detail depends on the camera specification. These thermogram's can also be stored for post survey processing, analysis and supplied to our customers. This allows the experienced thermographer to quickly and accurately survey most objects for heat differences, weaknesses etc.
When applied to building surveys and in trained and experienced hands, a thermal imaging camera is a very useful tool to quickly determine insulation weaknesses, damp and, under the right conditions, unwanted airflow patterns.
Our equipment is high specification and we are very experienced and trained in building surveying.
In our experience, thermal imaging in combination with the blower door to accurately determine the heat retention properties and heat loss mechanisms of a house is essential if you want to understand how your house looses heat before carrying out energy upgrades. Thermal imaging can also be used as a quality control for post upgrade works.
