Glidevale Protect solution for new build housing development

  • 9 Mar 2023

Leading building materials manufacturer, Glidevale Protect, has supplied its Protect Viking Air pitched roofing underlay across a new build development for housebuilder Pennyfarthing Homes in Verwood, Dorset.

Glidevale Protect’s high-performance air and vapour permeable roofing underlay has been installed by appointed roofing contractor Ford Roofing of Hampshire at Pennyfarthing Homes’ Potters Wood housing scheme, a bespoke development featuring a mix of new build two, three and four bedroom semi-detached and detached homes.

The Protect Viking Air roofing membrane was fitted across all the pitched roofs, including on apartments at the development.

The class-leading underlay helps avoid the risk of harmful condensation and achieves superior air permeability, tested at 50 Pascals to BS EN 12114, meaning it can be used in cold roof construction without additional roof space ventilation as accepted by the NHBC.

Market leading

Glidevale Protect’s premium underlay boasts the best air and vapour permeability on the market. It is independently certified by BM TRADA as well as having the strongest wind uplift resistance of its product type, making it able to be used in wind zones 1-4 at 345mm batten gauge, in accordance with BS 5534, without the need for additional counter battens or integral tape. This ensures Viking Air can be used across a large area of the UK and throughout Ireland.

Used in both cold and warm roof construction without the need for additional ventilation, thereby saving labour costs by avoiding the need for additional accessory products, Viking Air can also be wrapped over the ridge rather than needing to cut it short on each side, not only ensuring good ventilation and water tightness but also saving installation time. Its unique grid design also makes it easy to cut onsite.

‘Fitted the bill perfectly’

Steve Tyrell, construction director, says: “At Pennyfarthing Homes, our new build specification requires a solution to ensure continuous ventilation is provided to the roof space.

“The use of the innovative Protect Viking Air roofing membrane with its high level of air and vapour permeability fitted the bill perfectly and allowed us to design out additional ventilation, ensuring we could use a high-quality product that adds value to our overall pitched roof construction.”

Mark Ford, managing director at Ford Roofing Ltd, comments: “As an appointed roofing contractor for Pennyfarthing Homes, we used the Protect Viking Air underlay on all roofs across the Potter’s Wood development.

“This strong and robust membrane not only delivers good air permeability but is easy to fit, saving valuable time on the construction. Using Viking Air means that no additional ventilation products are required, making the job quicker for our team and simplifying the overall installation. I am pleased with the membrane’s overall performance during installation.”
