The width of single glazing. The warmth of double glazing.
Our revolutionary Pilkington Spacia™ vacuum glazing technology provides unrivalled thermal performance in an ultra-thin unit that fits seamlessly into listed and conservation properties. This innovative unit allows the character of the property to be retained as it can be used with the original frames. It can also be used as secondary glazing and where aesthetics are important in a new or modern property.
How It Works
Pilkington Spacia™ consists of an outer pane of low-emissivity glass and an inner pane of clear float glass, with a vacuum rather than air or gas between the two panes of glass. The result is excellent thermal performance from a unit only fractionally as thick as a standard doubled glazed unit.

See what our suppliers have to say
Tony Dee, owner and director of Grosvenor Restoration, said:
“The technology behind Pilkington Spacia™ helps us to deliver authentic sash windows with all the benefits of modern glazing.
“Being 6mm thick thanks to vacuum glazing technology, Pilkington Spacia™ allows us to create windows for period and listed buildings that delivers excellent thermal insulation while still fitting into original slim profiles.
“I always highly recommend the product. It performs to a high standard and often outperforms thicker and heavier double glazing.
“Slim window profiles and protected building features when working with listed properties mean fabricators are often restricted to single glazing - contributing to greater heat loss and less sound insulation. But with Pilkington Spacia™, our customers are enjoying less noise transmittance, warmer homes, and slashed energy bills - something they thought were the costs of living in a period building.”
Andrew Madge, managing director of Gowercroft Joinery, said
“Pilkington Spacia™ is an integral part of our new Heritage range of windows, which has been developed specifically for the listed property and conservation market.
By combining this ultra-slim vacuum glazing with our traditional joinery and detailing in Accoya® timber and our specially developed protective paint finish, we can offer our customers a truly unique solution which delivers the best of all worlds – that’s to say fully factory fitted, sustainable and low maintenance windows, with excellent thermal and acoustic efficiency that look just like the single glazed windows of the past!
"Thanks to this unique combination of innovation and craftsmanship, historic buildings can now benefit from windows made to the highest modern performance standards without compromising any of their traditional appearance."
The world’s first commercially available vacuum glazing. This extremely thin glazing can be fitted in old style fine frames, maintaining the original appearance of older traditional buildings whilst providing good thermal insulation.
- Thermal performance equal to or better than that of most low-e double glazing but in the same thickness as single glass
- Suitable as a replacement for single glazing in old frames, retaining the appearance of historic buildings and meeting the requirements for conservation areas
- Four times better thermal insulation than single glazing
- Suitable for other applications where use of thinner, low-weight glazing is desirable, such as sliding box sashes, secondary glazing, or as part of a triple glazed ‘super-window’
- Pilkington Spacia™ achieves higher levels of sound insulation than conventional glazing
- Proven solution; installed successfully in the UK and used in Japan for over a decade
- Offers reduced levels of internal condensation compared to single glazing
