More than 2,000 sheets of Norbord’s 11 mm Sterling OSB 3 have been incorporated into the timber wall panels of a new grammar school in Kirkwall, Orkney.
The material, which is made at Norbord’s Inverness factory from wood grown in sustainably-managed Scottish forests, was supplied to design-build contractor, Morrison Construction via the Orkney branch of Jewson.
Morrison Construction is the main contractor on Orkney Islands Council’s £58 million Schools Investment Programme. This scheme, which got underway in March 2011 and will take four years to complete, involves the construction of two new schools, a new halls of residence and a swimming pool complex.
The new Kirkwall Grammar School building comprises three teaching wings connected by an interlinking curved “street” which houses social and dining areas. A new oval-shaped Orkney Arts Theatre will be integral to the building.
Sterling OSB was specified for the highly-insulated timber panels which provide the main building envelope. They are combined with a variety of external finishes including copper cladding, natural stone, render and facing block. The building superstructure consists of a structural steel frame and its roof is aluminium standing seam system.
“This is by far the largest use of timber panels on any building I’ve seen on Orkney” says Brian Kynoch, manager of Jewson’s Kirkwall branch. “We supplied an initial order for 1,476 sheets of OSB and started shipping in January 2012. We then received an order for a further 738 sheets which were delivered in February.”
Timber components, as well as timber frame generally, have been widespread throughout Scotland for many years, its inherent thermal efficiency and speed of erection proving ideal for the Scottish climate. At Kirkwall Grammar School, the timber infill panels forming the external envelope were largely complete by late April, having been started only 12 weeks previously.
Sterling OSB3 is the UK’s best-selling oriented strand board for structural applications. Stronger than most softwood plywood and precision-engineered for consistent strength, the product is BBA approved and conforms to all relevant Eurocodes.
