Collaboration helps community campus achieve Passivhaus standard

Two primary schools, an Early Learning and Childcare Centre, and other community facilities will all be housed in the new £34m Faifley Community Campus in Clydebank. Due to be completed in 2026, the project is being delivered in compliance with the Net Zero Public Sector Buildings Standard as part of funding through the Learning Estate Investment Programme (LEIP2).  

As such, the new campus will be certified to the Passivhaus standard, which requires a thermally efficient, airtight building fabric. To achieve this, the campus’ external wall build-up features A. Proctor Group’s Wraptite UV external airtightness membrane. 

Architects Holmes Miller have embedded the Passivhaus standard into their work. Their track record in delivering Passivhaus-standard buildings includes East End Community Campus, which features A. Proctor Group’s standard Wraptite membrane. 

The Wraptite UV membrane allows the campus buildings to benefit from moving the airtight line to the exterior face of the external wall. Doing so avoids a lot of complex detailing (such as around services and other penetrations) that often occurs at the internal face. 

The composition of Wraptite UV makes it more resilient to the effects of UV exposure. It is typically used behind open-jointed cladding, though this wasn’t a consideration at Faifley Community Campus with its masonry and sinusoidal cladding facing materials. A benefit of Wraptite UV’s resilience is that it can be left exposed for longer if required, which may have benefited the construction programme in this particular case. 

Wraptite UV is fully adhered and doesn’t require a primer, saving on labour and material costs. It also vapour permeable, so it can achieve a high level of airtightness without increasing the risk of condensation.
