Pilkington Spacia™ Vacuum Glazing

Medium thermal insulation in only 6 mm


Pilkington Spacia™ is the world’s first commercially available vacuum glazing. It offers the thermal performance of conventional double glazing in the same thickness as single glass (6 mm).

Pilkington Spacia™ provides a real solution to the problems of balancing historical preservation with modern comfort and environmental requirements.


Pilkington Spacia™ has low overall thickness (6 mm) and good acoustic performance, making it ideal for use in historic buildings, offering replacement windows more in keeping with the original design. It may even allow the use of the original frames if these are in a reasonable or repairable condition.

Until now, the only choices were to sacrifice thermal performance and comfort, or to compromise the appearance of the building by using bulkier modern frames with double glazing.

Pilkington Spacia™ is also suitable for other applications where the use of thinner, low-weight glazing is desirable, for example in sliding box sashes, secondary glazing, or as one pane of a triple glazed “super-window”.
