It is common knowledge that improving insulation and blocking draughts is the most cost-effective way to reduce energy consumption and save money but how do you really know what needs to be done in a particular building? The simplest way is with a thermal imaging camera which quickly provides a visual representation of heat loss with no intrusive procedures.
The photos here were taken in a house built in 2008, looking up a triple height light well. The thermal image shows the double glazed skylight is working well. In the middle of the photo, wall insulation into the loft area behind is in place in strips. However at the top of the apex the blue area illustrates that there is no insulation meaning heat is being lost into the attic, the most common type of building inefficiency.
ReGlow can provide thermal imaging services to identify simple ways to improve building efficiency.
