Choice Housing in Lisburn City, Northern Ireland, selected a combination of roofing underlay and accessory products from Glidevale Protect, including the Protect Viking Air air and vapour permeable roofing membrane for a major re-roofing refurbishment programme.
The contract saw the building materials manufacturer work closely with one of the country’s largest independent housing associations, to re-roof 116 existing homes at its established Pond Park development.
Working with Choice Housing’s Assets Department and the appointed roofing contractors, Glidevale Protect provided a complete solution. Protect Viking Air was specified and installed to improve roof ventilation, minimise the risk of condensation and offer reduced labour time during installation too. Also supplied on the project was Glidevale Protect’s OFV eaves skirt, installed to avoid sagging and ponding of the underlay and ensure correct water discharge into the gutter.
Commenting on the project, Matthew McLaughlin, Building Surveyor for Choice Housing Ireland Ltd said: “We chose Protect Viking Air over other products as we required a premium roofing underlay offering a robust solution to dealing with condensation within its problem roof voids. Viking Air was chosen for its superior air and vapour permeability qualities which exceed BS 5250 requirements. Glidevale Protect’s technical team were excellent in the development of a suitable specification for the job.”
The Protect Viking Air roofing underlay specified not only boasts superior air and vapour permeability in both warm and cold pitch roofing applications, but can be easily wrapped over ridges rather than cut short of the roof apex and has been designed to be exceptionally easy to handle on site, requiring no additional ventilation in cold roofs as permitted by NHBC. Fully third party certified, Viking Air helps avoid the risk of harmful condensation in accordance with BS 5250 and NHBC requirements.
