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.

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

Energy-efficient glazing is the term used to describe the double glazing or triple glazing used in modern windows in homes. Unlike the original single glazing or old double glazing, energy-efficent glazing incorporates low-emissivity coated glass to prevent heat escaping through the windows.

Higher standards of air-tightness and thermal insulation in new build properties has meant some modern homes have become vulnerable to overheating. How glazing can help control the temperature of a home?

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.
