Pilkington energiKare™. Pilkington energiKare™ differs from basic double glazing as it works in two ways. It reduces the amount of heat lost through your windows, but also allows more heat (energy) from the sun in through the glass. This effect is known as solar gain and you’ll benefit from its effects all year round, for free.

This is the name given to our range of double and triple glazing which is used to improve the thermal efficiency of homes – reducing the amount of heat lost through your windows and can also allow more heat energy 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.
