Protect BarriAir, the air barrier membrane with vapour control properties has been used throughout a 68 home residential housing scheme at Saffron Acres in Leicester, achieving stringent levels of airtightness to meet the Passivhaus standard.
Used within a community-led initiative undertaken in collaboration with emh Group, Westleigh Partnerships Ltd and Saffron Lane Neighbourhood Council with consultation by Encraft, BarriAir was specified to ensure an airtight timber frame structure within a well-designed living space.
A former derelict site regenerated to address the shortage of affordable housing, Saffron Acres is the winner of the 2017 East Midlands Residential RICS Award and also the largest Passivhaus affordable housing development in Europe. Achieving certification in 2017, all 68 timber frame designed plots were awarded the standard, creating an environmentally friendly place to live.
Kyle McCabe, Assistant Site Manager at Westleigh Partnerships Ltd, commented, “The BarriAir product from Protect Membranes has delivered outstanding performance at our Saffron Acres development and testing was a key contributor to improved airtightness, resulting in the last home tested achieving 0.22 ach-1 at the first time of asking. The product was very reliable and good to work with, helping the scheme to achieve Passivhaus standard.”
Protect BarriAir is a high performance construction membrane for walls and ceilings, offering a significant reduction in air leakage, helping to meet Building Regulations and airtightness standards.Also offering vapour control properties, Protect BarriAir is installed on the warm side of the structure, adjacent to the insulation, offering reduced heat loss and convection flows to improve thermal performance.BarriAir is available with integrated tape and offers an effective sealant to further provide added assurance of airtight performance and ease of installation. Other Protect products used on this development included Protect VP300 vapour permeable roofing underlay and Protect TF200 external timber frame breather membrane.
