Pilkington Spacia™ Impresses At BRE

02 June 2011

Pilkington Spacia™ is the new name for market leading Pilkington energiKare™ Legacy – ultra-thin energy efficient glazing that fits seamlessly into traditional and conservation properties. This innovative glass from the NSG Group has been installed at the construction research consultancy, the Building Research Establishment (BRE).


The Victorian Terrace at the BRE, Watford has been refurbished into three energy-efficient home  incorporating Pilkington Spacia™

The Victorian Terrace at the BRE has been refurbished into three energy-efficient homes. One of the energy-efficiency problems of the property was its former sash windows. Victorian sash windows, whilst being aesthetically pleasing, are notorious for allowing heat to escape from a building. Not only are they mostly single glazed, they often do not fit snugly which can create draughts.

Pilkington Spacia™ was the perfect solution for the Victorian Terrace, as it is a highly energy-efficient glazing unit, yet is the same thickness of the existing single glazing. This enables period properties such as this Victorian Terrace to maintain their original look and charm, whilst also providing all the cost savings and comfort double glazing offers. Pilkington Spacia™ is vacuum glazing that has been installed successfully in Japan for more than 12 years.

John O’Brian, Principal Consultant, BRE, added: “The performance and look of the Pilkington Spacia™ units provide the perfect glazing solution, not only for the Victorian Terrace at BRE, but also for countless commercial and domestic listed buildings across the UK.”

The Victorian Terrace will now be monitored for several months to provide a convincing demonstration of the results achieved thought smart refurbishment. The targets for the property are: a minimum SAP of 80, CO2 emissions of less than 35kg/m2/yr, a whole property energy saving of more than 60 per cent compared to the energy saved before refurbishment, to produce at least 10 per cent of the energy the property uses.
