Completely invisible to the naked eye, any missing or deteriorated insulation can lead to heat loss and energy wastage. Especially in older buildings, insulation is a major issue in determining the energy efficiency of a building. Whether it is wall insulation or loft insulation, a thermal camera can detect any spots that need attention.

About 35% of the heat produced by your boiler will escape through the walls and through gaps, in and around windows and doors, and about 10% of heat will disappear through the floor. Collectively the roof, walls (+ windows and doors) and the floor are known as the thermal envelope.
If you can slow this movement of heat from inside the house, through the thermal envelope, to the external environment, you can dramatically reduce your energy bills.

In this example photograph the thermal image clearly shows insufficient insulation in the wall below the window as well as heat loss through the upper part of the window.

Missing Insulation

In this view from the inside, it is clear to see cold spots coming through the door causing draughts and heat loss.
