Pilkington energiKare™ is the name given to our range of double and triple glazing used to improve the thermal efficiency of homes. It reduces the amount of heat lost through your windows and can also allow more heat energy from the sun in through the glass.

Pilkington K Glass™ forms the inner pane of an energy-efficient double glazed unit, 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.
