Currie Community High School has been designed to provide 1,000 student places across three floors, with a focus on daylight, indoor air quality and healthy, natural materials, plus spaces for outdoor learning. The community aspect of the project features amenities including a library, sensory garden, and public allotments.
As well as the comfort benefits that come from attaining Passivhaus accreditation, the building’s low energy performance is designed to contribute to the City of Edinburgh Council’s net zero goals.
Sport and leisure facilities on the site include a swimming pool, meaning the school will have one of the few Passivhaus-certified pools in the UK; Kier Construction previously delivered the first certified leisure centre in the country, at St Sidwell’s Point in Exeter.
While most of the high school is of steel frame construction, the pool hall uses a cross laminated timber (CLT) structure. “We wanted to protect the timber kit as soon as possible,” said Cameron, “so for that part of the building we used Wraptite UV. It offered us a longer exposure time than the standard Wraptite, meaning we could complete that part of the building early on.”
Wraptite UV is typically offered for use behind open-jointed cladding, but in this instance supported the specific goals of the project following advice from the Proctor Group technical team.
Wraptite membrane was then used across the rest of the site. Both Wraptite products offer a combination of airtightness and vapour permeability, helping to meet low energy goals without increasing condensation risk in the structure. The self-adhered nature of the two membranes creates a consistent airtight seal without the need for a primer, saving on labour and material costs.
