The A. Proctor Group has, for nearly 50 years, been serving the construction industry with an extensive portfolio of technically advanced thermal, acoustic and membrane products. One of the worldwide leading and trusted brands in roofing membranes is Roofshield®. The recent changes to BS5534 the British Standard for Slating and Tiling continue to strengthen the case for Roofshield as a high-performance non-ventilated roofing solution.
The use of Roofshield will lead to savings in labour and material costs, due to no VCL being required, and its high-performance air permeability means that the roof space has similar air changes to that of a roof using traditional eaves/ridge ventilation.
Increasingly leading housing developers backed by the NHBC, and independent industry research, all agree that some underlays perform at an exceptional level, providing a failsafe option, without the need for additional ventilation. By specifying Roofshield developers are guaranteed the highest quality, pitched roof underlay, which is both air and vapour permeable.
