NBT features at Scotland’s first Housing Expo
NBT’s woodfibre insulation systems have featured in an exciting vision of the future of UK housing at Scotland’s first ever Housing Expo, which showcased the latest concepts in natural and energy efficient housing. The aim of the event was to inspire forthcoming housing developments across the Highlands and the rest of the UK. The Expo comprises a total of 52 homes, all of which are based on architects’ winning design entries in the 2007 Royal Incorporation of Architects in Scotland competition.
Thirteen of the Expo’s 25 architects specified a variety of NBT’s high performance, recyclable woodfibre systems, such as Diffutherm, Pavaclad and Pavaroof. This includes Oliver Chapman Architects, who designed the ‘Skewed House’ on Plot 23. Named as a result of its unique, offset roof ridgeline, this single-storey, timber frame property uses NBT Isolair woodfibre boards to insulate the external walls, with NBT Pavaflex woodfibre batts as infill insulation between the studs. Pavatherm Profil is used to insulate the floor, and NBT Pavaflex batts are used between the rafters.
In addition to their outstanding natural and sustainable credentials, the woodfibre products have the capacity to offer occupants an optimally comfortable living environment with minimal energy costs. Mark Cousins, Associate Director of Oliver Chapman Architects, comments: “We felt that NBT’s systems were an obvious choice given the aspirations of the Expo to promote truly sustainable living.”
Through the formation of a thermal shell, NBT’s woodfibre insulation reduces thermal bridging, which, combined with its excellent thermal conductivity, provides excellent thermal insulation. Indeed, the application of these products led to a considerable improvement in the thermal performance of the ‘Skewed House’ compared to Building Standards at the time of application, with an improvement of 25% for the walls, 14% for the floors, 42% for the roof, and 22% for the windows.
The hygroscopic properties of the woodfibre material makes it fully breathable, meaning that its use reduces the risk of interstitial condensation, resultant mould formation and the associated health risks to occupants and structural risks to the frame.
Both the roof and the exterior walls of the ‘Skewed House’ are over-clad in cedar shingles. In addition, as a low carbon energy provider, an air source heat pump is installed, which serves the hot water and under floor heating systems of the property.
