Project: Hakin Community School, Milford Haven, Pembrokeshire
Main Contractor: Willmott Dixon
Architects: Lawray Architects/Austin Smith Lord Architects
Products specified, Treatment Services applied under ISO 9001 factory controlled conditions and installed
Working closely with both Lawray Architects initially, a specification was created utilising a PEFC-certified NORclad® European Redwood. Koppers MicroShades “Brunnea” treatment was requested to offer a formal warranty on the product for 30 years against rot and fungal decay (out of ground contact), along with a good level of colour stability VS traditional untreated species.
To create depth, a board on board arrangement was selected for the majority of the project, with detailing in soffit areas carried out in a T&G profiled board, NWC2. This was due to not only access, but weight limitations. With a mix of profiles, the criteria was to keep the variations minimal, 25 x 150mm boards for both the NWC2 profile, and the larger of the two board on board profiles, the other being 25 x 75mm.
As the specification developed, Austin Smith Lord became involved with detailing, and the highlight was raised of fire. NORclad were able to offer Fire treatment to Euroclass B-s1-d0 (s1 Smoke Production – d0 Flaming Droplets), fully compatible with the currently specified cladding. The same fire treatment was applied to the backing structure battens that we supplied, this time a regularised whitewood item.
