Thermal bridging in external walls: Stage two

Verney Ryan, Guy Penny, Jane Cuming (Part One only), Mal Riley (Part One only).

Stage Two focused more deeply on the causes, impacts and potential solutions to the high percentages of timber framing and thermal bridging found in Stage One. The research explores the drivers for the rates of framing identified during design, detailing and frame and truss manufacturing; the impacts of the current percentages of framing alongside uninsulated weak points and thermal bridging issues and the effect these have on wall R-value; and advanced framing and insulation solutions to address the range of issues identified.
