May 2025 marks one year since Proctor Air by A Proctor Group was awarded its BBA certificate.
Developed based on feedback from designers, specifiers and installers, Proctor Air is an air permeable, low-resistance (APLR) pitched roof underlay. A Proctor Group said its air permeability means no ventilation measures are required in warm, cold or room in the roof constructions. Proctor Air has achieved a W1 resistance to water penetration classification and a minimum of 1m hydrostatic head.
The underlay has been used on various projects, including the Hatchmeadow apartments in Northumberland where it featured in a 2500m2 replacement roofing system. The company added that Proctor Air helped to protect residents during the work, as the building remained occupied throughout. The completed system stopped leaks that had previously affected some of the apartments.
It has also been used on the £325m renovation of Manchester Town Hall. A Proctor Group stated that the historic roof features many intricate details with limited opportunities to provide modern roof ventilation. Installing Proctor Air meant separate roof ventilation was not required, it noted, and there will be no ‘dead zones’ of restricted air movement in the complex roof.
In December last year, A Proctor Group won in two categories at the Construction Marketing Awards (CMAs). The judges named the business as winner in both the Best Product Launch category and the Best Advertising Campaign category.
Looking ahead to the rest of 2025, the A Proctor Group said it continues to support specifiers and installers in adopting air permeable membranes. Forthcoming developments include new technical guidance on using Proctor Air with in-line solar PV panels.
