Next generation roofing underlay offers superior air permeability and strong wind uplift resistance

Building products manufacturer Glidevale Protect has launched Viking Air, an independently certified air and vapour permeable (LR) roofing underlay for cold and warm pitched roofs.  

By delivering class-leading air and vapour permeability, Viking Air ensures a high level of airflow and ventilation is provided into the roof space, reducing condensation risk in line with BS 5250.  The product can be used without additional ventilation, which is acceptable to the NHBC for a cold roof construction.   

The product is suitable for use in wind zones 1-4 at 345mm batten gauge to BS 5534, with no need to tape laps or use additional counter battens.  When the membrane is installed at 310mm batten gauge or on sarking, it also meets wind zone 1-5 requirements, ensuring unrestricted use across the UK and Ireland.

Viking Air forms an integral part of Glidevale Protect’s roofing membrane family, which includes LR vapour permeable and airtight options, impermeable HR underlays together with ventilation products and accessories, giving specifiers and contractors a single source solution, whatever their pitched roof challenges.
