Looking back at the last 25 years, we can trace many changes to energy efficiency regulations. We can highlight the evolution of important standards like BS 5250. Above all, we can see how our climate has changed in that time.
We also understand how the climate is likely to continue changing. That means we can, and should, be creating products capable of dealing with the increased frequency and intensity of extreme weather.
In other words, innovation is vital to future-proofing buildings.
As a 4th generation family business, Proctor Group has a history of technical innovation, promoting good practice, and developing products that roofing contractors want to use. We applied this wealth of experience to creating our air permeable and vapour permeable (APLR) underlay, Proctor Air®.
Hidden from view, pitched roof underlays usually warrant little attention from building users. Yet they play a vital role in protecting those users from the elements, and from unhealthy indoor climates.
By choosing and installing Proctor Air, specifiers, contractors and building owners can enjoy the confidence that comes from a high-performance product doing its job without intervention.
Proctor Air’s water resistance has been tested and, having a water hold out performance of more than a 1m head of water, meets the guidance of the NFRC’s Technical Bulletin TB06.
While stopping external moisture getting in, a low resistance underlay must also allow water vapour out. Since Proctor Air permits the passage of both air and moisture vapour through the roof construction, no VCL is required in the ceiling and no ventilation measures are required in the cold roof space.
Avoiding the need for ventilation – particularly at the eaves – helps when it comes to installing the substantial thicknesses of insulation required in lofts. With the impending introduction of new energy efficiency regulations, those thicknesses may well increase.
Rooftop solar is also expected to be made compulsory as part of the Future Homes Standard in England.
We have recently published industry-leading research demonstrating the compatibility of Proctor Air with integrated PV panels. Confusing technical guidance made specifiers and housebuilders unwilling to use the two together. Our recommendation gives the roofing sector the confidence it needs to fully embrace new solutions.
There has never been a more important time to deliver innovation, and Proctor Air is an underlay that makes pitched roof constructions simpler while delivering performance ready for the future.
