Window Upgrades

Energy-efficient window upgrades from Clement Double Glazing

Did you know that the type of glass you use in your windows can help your home be more energy-efficient? Did you know that over 25% of the heat in your house escapes through your windows?

Replacing the heat lost through your windows can be expensive. Don't throw your money out of the window! Install energy-efficient Pilkington energiKare to your existing windows and you can help to reduce your heating bills by up to 20% each year.

You can also take satisfaction in the fact that it is not only money you are saving. Using Pilkington energy-efficient glass will reduce your home's CO2 output, making your carbon footprint smaller and your home more environmentally friendly.

We offer a range of Pilkington energiKare energy-efficient glazing to suit every type of property, from a modern home to an older traditional styled home. The insulating glass units range from one unit which is ultra-thin to upgrade single glazing, to double glazing in older properties, and to help to retain the aesthetics, a range of double glazed units up to our range of high performance triple glazing. It is even possible to just replace the double glazing units into your existing frames.

Pilkington energiKare glazing incorporates a choice of glass from the Pilkington K Glass range, our market leading low-emissivity glass. It is made into double glazing known as insulating glass units.

Upgrading wooden windows with Pilkington's Spacia Unit

Formerly Pilkington energiKare Legacy, the revolutionary Pilkington Spacia vacuum glazing technology gives you unrivalled thermal performance in an ultra-thin unit that fits seamlessly into traditional and conservation properties. With this innovative unit you can retain the aesthetics by using the original frames. Pilkington Spacia, provides the most advanced new solution for an age-old problem.

How It Works

Pilkington Spacia consists of an outer pane of low-emissivity glass and an inner pane of clear float, with a vacuum rather than air or another gas in between. The result is excellent thermal performance from a unit only fractionally as thick as a standard Insulating Glass Unit (IGU).


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.

  • Thermal performance equal to or better than that of most low-e double glazing in the same thickness as single glass, offering the opportunity to improve energy efficiency in historic buildings.
  • Five times better thermal insulation than single glazing provides lower heating bills.
  • Suitable as a replacement for single-glazing in old frames, retaining the appearance of historic buildings and meeting the requirements for conservation areas.
  • 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'.
  • Also offers good acoustic performance for lower noise.
  • Proven solution; successfully used in Japan for over a decade.
  • Offers reduced levels of internal condensation compared to single glazing.
