  • Rooflight manufacturer Xtralite has added products, including from its X-2 range, to the National BIM Library. The products which are now available on NBS feature the full technical details such as UV ratings, dimensions and suitability statistics.

Catnic


Roofing and cladding system

Catnic’s SSR2 Standing Seam Roofing and Cladding system were specified for a new-build extension in West Lothian. The company said the products were chosen to work both with the traditional finishes of the old building and the more contemporary finishes featured on the new extension. A 48° roof pitch was created using the Catnic SSR2, as well as a flat roof element. The SSR2 system meets the legislation of load bearing for wind speed in accordance with EN 1991-4 and weather tightness in accordance with BS 5534 Parts 1 and 2.

Single ply membrane
A single ply membrane from SIG has been chosen for Lymington Shores, a residential development in Lymington. Rhepanol fk PIB single ply membrane is 100% recyclable and has a full life cycle assessment to ISO14040. The company says it was chosen due to its sustainable credentials. Almost 12,000m2 of flat roofing, pitched roofing with standing seam, terraced areas and cold roof build ups to bin stores and valley gutters were installed on the project.

Reinforced bitumen system
More than 7,200m2 of Bauder’s reinforced bitumen system, Bauder Total Roof System, has been used to repair the failing roofs at Airedale Academy in Castleford. The project was challenging as the roof had more than 20 separate roof areas. The system build-up included Bauder’s PIR Insulation with the required levels of thermal performance and tapered insulation to create drainage falls without having to incorporate them into the structure. As part of the works, 20 new Bauder rooflights were also fitted.
