Thermal Insulation Improves the energy efficiency of domestic or commercial buildings whilst enabling the extensive use of glass and the benefit of passive solar gain. Find out more about Energy Efficiency

Our revolutionary Pilkington Spacia™ vacuum glazing technology provides 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 Insulight™ Therm are double glazed insulating glass units incorporating Pilkington Optifloat™ Clear glass and low emissivity glass products from Pilkington K Glass™ or Pilkington Optitherm™ range.

The Pilkington Optitherm™ Range are high performance, off-line coated low-e glass products specially developed for use in Insulating Glass Units (IGUs) to help with energy saving. They are optimised for thermal insulation having ultra low Ug values and are super neutral in colour.

Pilkington Energy Advantage™ is a pyrolitically on-line coated low-emissivity glass. It offers substantial improvement on thermal insulation when compared to clear float glass.

In thicknesses above 6 mm, it can be used for a variety of commercial applications where superior strength, greater spans, reduced deflection, high daylight transmission and noise reduction are required. Pilkington Optifloat™ Clear can be toughened or laminated for impact safety and security.

Unlike the original single glazing or old double glazing, energy-efficent glazing incorporates low-emissivity coated glass to prevent heat escaping through the windows. This makes the windows highly thermally insulating hence improving the energy efficiency of your home and helping to save money on your heating bills.

The high selectivity index (light-to-heat ratio) of Pilkington Suncool™, combined with the highest level of thermal insulation reduces the need for cooling and heating systems in your building, lowering running costs and helping to make your building ‘green’.

The good insulation offered by Pilkington K Glass™ makes the inner pane of a window much warmer. This eliminates cold spots, increases the amount of usable floor space and helps reduce unsightly internal condensation.

Pilkington K Glass™ N forms the inner pane of an energy-efficient IGU, such as Pilkington Insulight™ Therm. The coating reflects heat back into the room.
