How Pilkington energiKare™ works
Pilkington energiKare™ reduces the amount of heat loss through windows and it also allows more heat (energy) from the sun in through the window - this effect is known as solar gain.
As solar gain is heat from the sun, it's 'free of charge' and available all year round.
Pilkington energiKare™ contains two special types of glass:-
- Pilkington K Glass™, the UKs best selling low emissivity glass which stops heat escaping from homes.
- Pilkington Optiwhite™ is a special 'extra-clear' type of glass. It increases the degree of solar heat gain and makes home feel warmer without the need to turn up heating.
- Filling the double glazed unit with argon gas or using air filling with a new "warm edge spacer bar" stops further heat escaping from homes.
