Roofing contractor: Hereward Roofing
Type of works: design, manufacture and supply of Hambleside Danelaw's GRP valley troughs.
GRP valley troughs designed and manufactured by Hambleside Danelaw are a feature of award-winning slating work on a Peterborough hospital. The British roofing products were chosen by Hereward Roofing who won the slating category in the National Federation of Roofing Contractors Roofing Excellence Awards 2009.
The winning work was carried out on the Mental Health Unit at the Edith Cavell Hospital in Peterborough. A distinguished panel of judges unanimously chose Hereward Roofing as its entry demonstrated quality workmanship, their ability and professionalism to overcome considerable technical difficulties as well as the environmental qualities and aesthetics of the project.
As part of the product range which met the technical challenges, Hereward Roofing used Hambleside Danelaw’s GRP valley troughs which tick all the right boxes on sustainability. The high-capacity range with mortar bonding strips and mortar retention bars in standard Lead Grey colour are available in 2.4 and 3m lengths.
The valley troughs are among the many roofing and ventilation products currently produced by Hambleside which feature recycled materials in their construction, a process which has been recognised by the Green Organisation and the Waste and Resources Action Programme (WRAP). Specifiers, especially those for public sector new-build projects, will be interested to learn that the Group’s tile roof ventilator range has now been added to the WRAP Procurement Guide for construction materials that incorporate recycled content and help to reduce waste.
There are alternative GRP valleys available within the UK market, but Hambleside's range has been developed to meet fully the requirements of the NFRC Technical Bulletin TB28 which is now referenced in BS 5534:2003. In order to meet this Standard, the production process does require greater raw material usage during manufacture, but this results in a high-quality long-life product.
Chris Dalgarno, Hambleside Danelaw’s Director of Sales - Roofing and Ventilation, said: “It is really pleasing to see our colleagues at Hereward Roofing gain national recognition for the quality of their workmanship. Hambleside Danelaw is delighted that quality contractors regard our roofing and ventilation products as a first port of call when looking for sustainable solutions.”
