Improves the energy efficiency of domestic or commercial buildings whilst enabling the extensive use of glass and the benefit of passive solar gain. Today's builders, regulators and wider communities are demanding more from glass.

Our revolutionary Pilkington Spacia™ vacuum glazing technology provides unrivalled thermal performance in an ultra-thin unit that fits seamlessly into traditional and conservation properties.

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 standard gas in insulating glass units is dry air. The space between the glass panes can be filled with other gases that have different properties that improve the thermal resistivity. Argon and krypton are the most likely alternatives. Krypton is beneficial if the space is limited.

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.

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.

Pilkington Eclipse Advantage™ can be combined with another low-emissivity glass in an Insulating Glass Unit to achieve even higher levels of thermal insulation.

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. NSG Group have been at the forefront of development of glass products which enable this to be achieved.

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.

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?
