Pilkington Spacia Glass

Using advanced Pilkington Spacia™ technology, this is the world’s first commercially-available vacuum glazing. It allows the manufacture of extremely thin glazing which can be fitted in old style fine frames, maintaining the original appearance of older traditional buildings.

Pilkington energiKareTM Legacy provides a similar level of energy efficiency as modern double glazing, but in a unit that is typically only a quarter of the thickness. This brings a new level of thermal performance to older buildings, and opportunities for slim glazing in new buildings.

  • The thermal performance of modern double glazing in the same thickness as single glass, offering the opportunity to improve energy efficiency in older traditional buildings.
  • A cost effective method of improving the energy efficiency of older homes where glazing choice is restricted or where the original frames are a desirable feature.
  • Pilkington provide an extended warranty to your installer. Ask your installer for maintenance guidelines.
  • Four times better thermal insulation than single glazing, meaning lower heating bills.
  • Suitable as a replacement for single-glazing in original frames, to retain the appearance of older traditional buildings and meet the requirements of conservation areas.
  • Suitable for other applications where use of thinner, low weight glazing is desirable, such as sliding box sashes.
  • Greater comfort, as cold spots close to the window are reduced.
  • Offers good acoustic performance for lower interior noise levels.
  • A range of non-rectangular shapes, for flexibility with original frames.
  • Proven solution; successfully used in Japan for over a decade.
  • Offers reduced levels of internal condensation compared to single glazing.
