Heritage Sealed Units were needed to update this historic Private School near Derby without ruining it’s very distinctive appearance. This very sensitive project needed windows that were both traditional in appearance but modern in performance.

Single glazed units are the preferred products for heritage projects. Unfortunately ‘old school’ looks come with ‘old school’ performance in terms of heat retention and soundproofing. However, with the use of Pilkington Spacia™* heritage sealed units these problems can be overcome.

These double glazed units are considerably narrower than other windows – up to 15 mm thinner. This eliminates the ‘double shadow’ effect that prevents standard units from being used in heritage projects. The vacuum gap between the panes of glass makes them highly efficient whilst maintaining, as close as is currently possible, the appearance of an ‘original’ single glazed window.
