Summary

Thermal bridging occurs in all construction types and is cause by areas of reduced insulation or where an element passes through the insulation. Wood has a lower thermal resistance than the insulation materials placed between the framing members. Therefore greater heat flow occurs through studs, plates, rails and joists than in other areas of the external wall or roof structures. This increase in thermal conductivity is referred to as thermal bridging. In general, thermal bridges can occur at any junction between building elements or where the building structure changes.

Case studies

Steve Macken and his wife Deborah run their own wind farm development business, Lomond Energy, from their home just south of Loch Lomond. Given their business interest in renewable energy development, they had a natural and pragmatic desire to develop the property to high energy-effi ciency standards, primarily to control costs and achieve a good return on their investment, but also to reduce their carbon footprint.

The Great Barn at Harmondsworth is the largest timber-framed medieval building in the country and one of the few surviving:
a magnificent and remarkably preserved Grade I-listed building which is nearly a thousand years old.
