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

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.

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

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.

Thermal insulation Keeping heat inside. It is important to ensure that you do not lose the heat from your home through your windows. Efficient glass will enable you to reduce energy costs, make your home more comfortable and reduce the carbon emissions which will damage the Earth's atmosphere.

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 Optitherm™ S1A is an off-line coated, low-emissivity glass, offering superior thermal insulation performance with Ug-value of 1.0.

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’.

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.
