Proctor Group has launched a new guidance document aimed at helping construction professionals deliver better-performing, more comfortable buildings.
The new Thermal Bridging and Junction Design in Building Envelopes Guide explores how thermal bridging affects energy efficiency, comfort, condensation risk and building durability. It goes on to explain how careful junction design and continuous insulation can help reduce heat loss in new-build and retrofit projects.
Proctor Group is an Innovation Member of the Retrofit Academy, and the Academy has reviewed the guide. They said that it provides: “a useful introduction to those retrofit professionals who haven’t fully explored the role of thermal bridging in energy efficiency of buildings.”
Details are provided for three scenarios commonly found in both retrofit and new-build: roof abutments, window reveals and heads, and constrained wall areas (e.g. which cannot accommodate full thickness EWI).
As part of the guide, Proctor Group has included practical details showing how Spacetherm® aerogel insulation solutions can address these challenging areas.
Aerogel is a hydrophobic material, so it doesn’t absorb liquid water from wet walls. But its vapour openness allows moisture vapour to pass through, helping to maintain breathability in traditional forms of construction.
“The document will be useful to designers and coordinators who are looking for alternatives to fossil fuel-based insulation products that are not vapour permeable.”

“Thermal bridging is one of the most critical, yet often underestimated, aspects of building performance. Modern construction places significant emphasis on insulation, airtightness, and energy efficiency. Even small discontinuities in the thermal envelope can undermine efforts to deliver high-performance, comfortable buildings.”
