Thermal Bridging

Thermal Bridging

A major factor in the performance of the building fabric is not simply the amount of insulation you install, but how it interconnects with other components and the other insulated elements within the design. It has been estimated that up to 30% of the heat loss in a well-insulated building is through these ‘Non Repeating Thermal Bridges’. It is critical when calculating the performance of low energy buildings that this heat loss is measured and minimised. New module launching soon.
