Passive Purple - Vapour Control, Airtight & Smoke Tight Paint (11.4kg) - Spray / Roller Applied
£99.99Supporting the Next Generation of Engineers
Oxford Brookes University has expanded its Headington Hill Campus with the creation of a state-of-the-art Workshop building designed to support mechanical engineering, motorsport and advanced manufacturing education. Designed by ADP Architecture and delivered by Willmott Dixon, the development provides a new home for the Faculty of Technology, Design and Environment while supporting the university's commitment to innovation and sustainability.
Built Around Performance
The specialist facility includes industry-standard manufacturing workshops, engineering laboratories, wind tunnel testing facilities and engine test cells. As a building dedicated to engineering excellence, maintaining a controlled internal environment was a key project objective.
To support these requirements, Passive Purple was specified as the primary airtight vapour control membrane. Applied directly to the blockwork substrate prior to the installation of External Wall Insulation (EWI), Passive Purple helped create a continuous airtight layer throughout the building envelope.
Airtightness Designed In
Passive Purple was spray-applied across the external masonry structure to minimise air leakage and improve thermal performance. Window interfaces were detailed using EPDM connections bonded directly to the blockwork, creating airtight and weathertight junctions while reducing thermal bridging risks. Scaffold tie holes and other penetrations were subsequently sealed using Passive Purple Brush, creating a seamless continuation of the airtight layer.
Supporting Net Zero Goals
The project team selected Passive Purple due to its alignment with the project's sustainability objectives. Its liquid-applied application method, VOC-free formulation and ability to significantly reduce uncontrolled air leakage contribute to improved building performance and lower operational carbon emissions. The result is a high-performance educational facility that supports both student learning and long-term environmental goals.
