New CAD details from Polyfoam XPS will help designers, specifiers and installers to get the best results from extruded polystyrene (XPS) insulation.
The details, which are available in both PDF and DWG format, reflect current best practice in traditional XPS applications like ground floors, basements, and inverted flat roofs. They also include a new application, showcasing how XPS can be used in masonry cavity walls below DPC.
“We’ve put a lot of work into ensuring these new details really help people get the best performance in common details,” said Rob Firman, Technical and Specification Manager at Polyfoam XPS.
“New energy efficiency requirements in the Building Regulations continue to emphasise the importance of good junction detailing and minimising thermal bridging,” Rob continued. “Accredited Construction Details have been discontinued so it’s important that, as an insulation manufacturer, we give people the tools to help them deliver high performance buildings.”
Traditionally, XPS insulation is associated with ground floor and inverted flat roof constructions. But its moisture resistant properties also make it ideally suited to being used at the base of external walls, below DPC level.
Rob Firman added: “We recently published a white paper outlining how XPS insulation can be used to prevent issues with moisture below DPC in external wall build-ups. Making these new details available enhances the support we’re offering to people looking to get this crucial area of the building right.”
