Passivhaus homes to benefit from high performance insulation

Construction has begun on the largest Passivhaus development in the UK.

The Perryfields development in Dorset will have 66 energy efficient homes and provide a mixture of private and social housing.

The development is being built by Lomand Homes and will feature energy saving and environmentally friendly insulation systems.

Natural Building Technologies (NBT), a supplier of sustainable building envelope systems, will provide the high performance woodfibre insulation for the project.

The insulation will give high levels of thermal performance and airtightness and also prevents summer overheating.

It will be installed in the walls and the roofs of the buildings. The woodfibre insulation is fully breathable, which reduces the risk of mould formation.

The woodfibre boards have an over 95% waste wood composition, which make them completely recyclable. They also lock approximately one tonne of carbon dioxide for every tonne of product used.

The construction of the development is expected to be completed by spring 2012.

NBT will be demonstrating their systems at Ecobuild 2011 at ExCeL in London in March. Alison Brown
