A number of buildings at Durham University's Durham Project, a major redevelopment, have been clad with Tanalised Clear pressure-treated timber protected using Lonza Wood Protection's Tanalith M metal-free wood preservative.
Barclay Roofing has created a Tanalised Clear pressure-treated Western red cedar rainscreen system that curves around the walls of the buildings, part of the Gateway section of the Durham Project. The rainscreen system has been designed both as an attractive finish in keeping with the Gateway development's goal for an environmentally sustainable rebuild, and to prevent water getting to the structure of the building. Barclay Roofing installed the rainscreen under contract to the main contractor, Laing O’Rourke.
As well as providing up to 30 years protection against possible decay and insect attack, Tanalised Clear pressure-treated timber is also protected from certain fungi which can stain or discolour the wood. This new and innovative treatment helps retain the natural colouration of the wood, keeping it looking cleaner and brighter for longer.
Barclay Roofing managing director Paul Trelease said: "We were asked to use Western red cedar because it’s an attractive and versatile timber that doesn't split and has a long life. However, it can discolour very quickly. Using Tanalised Clear pressure-treated timber will help stop this discolouration and enhance the aesthetics of the building for a prolonged period."
Tanalised Clear pressure-treated timber has proven performance against fungal decay and insect attack, and is designed for exterior cladding, decking and timber building applications that are out of ground contact and where an uncoated finish is required.
The Durham Project is a multi-phase estates programme that aims to enhance Durham University's provision of world-class facilities for research, education, administration and community and cultural engagement, as well as enhance the overall city environment and opportunities. The Gateway section of the project aims to redevelop a key University site into an environmentally sustainable build of the highest standard.
