Willmott Dixon- Liquid applied Airtightness by Intelligent Membranes

OVERVIEW

Passive Purple Airtightness Solution for Willmott Dixon at Oxford Brookes University

This case study explores how Passive Purple was used to achieve high-performance airtightness at Oxford Brookes University, as part of a major project delivered by Willmott Dixon. Using our Guaranteed Airtight Supply and Install Package, Passive Purple—a liquid-applied vapour control membrane—was applied directly to the building fabric, delivering Passive House-level airtightness. The solution ensured long-term energy efficiency, reduced air leakage, and supported the project's low-carbon construction goals
