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.

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.

Benefits

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

Improves energy efficiency and maintains aesthetics in a range of older and traditional properties.

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
