Building products manufacturer Glidevale Protect has launched Viking Air, an air and vapour permeable (LR) roofing underlay for cold and warm pitched roofs.
Air and vapour permeable membranes are becoming an option of choice for specifiers due to the ability for the underlay to provide airflow and ventilation into the roof space of the dwelling. Protect Viking Air delivers the solution to this requirement through class-leading air and vapour permeability. This reduces the risk of condensation in line with BS 5250, without the need for additional ventilation, which is acceptable to the NHBC for a cold roof construction.
Viking Air’s resistance to wind uplift ensures suitability 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.
Tough and durable yet easy to handle, even in low temperatures, Viking Air offers a specific grid design to make precise cutting simple. The underlay can be laid straight over the ridge without cutting material short, ensuring the roof is instantly watertight during the construction stage, and, because the membrane is hydrophobically treated, it provides extra water shedding properties and a high resistance to water penetration.
“We believe we’ve created a new era of air permeability performance and a game-changer with Protect Viking Air,” said John Mellor, Senior Product Manager, “it adds a next-generation, technically advanced option to our portfolio. We’re confident that whatever the specification, we have the complete solution or combination of products that give our customers the right mix of performance and value, every time. Whatever the project, wherever the location Glidevale Protect has it covered.”
Viking Air forms an integral part of Glidevale Protect’s roofing membrane family. This includes LR vapour permeable and airtight options, alongside impermeable HR underlays which can be twinned with Glidevale Protect ventilation products and accessories, giving specifiers and contractors a single source solution, whatever their pitched roof challenges.
