Templeton, the grand former home of Sir Winston Churchill in Roehampton is currently undergoing a transformation from a student residence for the University of Roehampton into a unique and luxurious family home.
A combination of high-end bespoke carpentry and an innovative vacuum glazing product, Pilkington Spacia™, which delivers the thermal performance of high-performance double glazing but with a total thickness of just 6.5mm – close to that of single glazed windows was chosen to enhance the houses' energy performance.
Pilkington Spacia™ features a vacuum, minimising conduction of heat through the unit. The spacing between the sheets of glass is maintained using a grid of transparent microspacers – small pillars measuring just 0.5mm in diameter, placed 20mm apart across the unit.
As well as the thickness of the glass, another stipulation made by the conservation officer was that the double reflections often associated with double glazing be avoided, and this is another feature of Pilkington Spacia™. Because of the presence of the microspacers limiting deflection of the glass panes, Pilkington Spacia™ produces no discernible double reflection.
