Pilkington K Glass™ – Energy-efficient glazing

With its low emissivity coating, Pilkington K Glass™ is the UK’s leading thermal glass and has for over 21 years been the trusted solution for energy efficiency.


Pilkington K Glass™  forms the inner pane of the latest energy efficient insulated glass units, such as Pilkington energiKare™. The coating reflects heat back into the room whilst also letting in free heat from the sun, known as passive solar gain. By using this thermal insulation glass in your windows you can achieve a high Window Energy Rating to comply with energy saving Part L Building Regulations 

Pilkington energiKare™  has been specifically developed to reduce energy loss through your windows by up to 75%, at the same time taking advantage of the free heat energy from the sun helping to reduce your heating bills.

How Pilkington energiKare™ works

The high performance of Pilkington energiKare™ energy-saving glazing is achieved through the combined use of two very special types of glass, both of which make up the insulating glass unit.  By using Pilkington K Glass™ (a special low-emissivity glass) as the inside pane, this energy-efficient glazing not only reflects heat back into the home greatly helping to reduce heat loss, but also allows in the energy gain from a free energy source – the sun.  By using Pilkington Optiwhite™, an “extra clear” low iron glass as the outside pane, the free energy is allowed to pass through to the next pane maximising the benefits of this free energy source.

Pilkington energiKare™ energy-saving glazing is suitable for any age of building, if you are thinking of replacing your current window glass, choose Pilkington energiKare™

Pilkington Activ™ Self-cleaning Glass

Long described as an impossible dream, self-cleaning glass is now a reality. After years of research and development leading glass manufacturer Pilkington has introduced the Pilkington Activ™ range of products. The range has products which combine both self-cleaning and solar control properties, making them highly desirable amongst homeowners looking for the ultimate in glass solutions.

Pilkington™ Texture Glass

For privacy, pure style or to allow more light into internal rooms, Pilkington Texture Glass gives you a fantastic range of attractive options.

The Pilkington range gives you no fewer than 18 different designs, together with our premium range of etched glass. From classic to contemporary, no one offers a bigger choice of original patterns.

Pilkington Optiphon™

With increasing traffic on the road, rail and in the air, noise insulation has become a very important topic. It is not a question of it being a luxury anymore it is essential that noise reduction is considered in the specification of the glazing.

Pilkington Optilam™

Pilkington Optilam™ is the brand name for our laminated glass range.  Pilkington Optilam™ is ideal for providing both impact resistance and security since it may break on impact but the glass is held in place thus preventing injury or intrusion.

Pilkington Optilam™ is produced by combining two or more sheets of glass with one or more plastic interlayers.  The performance of Pilkington Optilam™ can therefore be varied by changing the number and thickness of each of the glass panes and the polyvinylbutyral (PVB) interlayers to give the specifier a wide choice of products depending on application, whether it be for safety or security, noise control, solar control, UV screening, bullet and blast resistance or privacy and decoration.

Pilkington™ Toughened Glass is up to five times stronger than ordinary glass of the same thickness. It meets world-wide safety standards for glass subjected to accidental human impact at the highest level of severity. Wherever the benefits of ordinary glass need to be combined with extra strength, safety or heat resistance, Pilkington Toughened  Glass can offer a complete and proven solution.

Pilkington Toughened Safety Glass is manufactured by subjecting final size, edge-worked panes of glass to a heating and cooling treatment whereby high compressive stresses are set up at the surfaces with balancing tensile stresses in the centre. The high compressive surface stresses give the Pilkington Toughened Glass its increased strength.
