How it Works
Pilkington energiKare™ is different to standard double glazing as it works in two ways. It reduces the amount of heat lost through your windows and it also allows more heat (energy) from the sun in through the window. This effect is known as solar gain and as it comes from the sun it’s free of charge.
Pilkington energiKare™ is made up of two special types of glass, Pilkington K Glass™, the UK’s best selling low emissivity glass which stops heat escaping and Pilkington Optiwhite™, a special ‘extra clear’ glass which allows more solar heat in through the windows.
What’s more, windows
containing Pilkington
energiKare™ can achieve the
EST’s Energy Saving
Recommended status. Once
incorporated in suitable
framing material it will
normally achieve a minimum
BFRC Window Energy Rating of
C and can be improved to B
or A by the addition
of Argon gas filling or warm
edge spacer bar
technology. Pilkington
energiKare™
Insulating Glass
Units are manufactured by
approved licensed IGU
processors then fabricated
and sold through approved
registered window companies
across the country.
Installing Pilkington energiKare™ will help reduce your household’s energy usage and CO2 emissions.
Understanding window energy ratings
The Window Energy Rating System measures the efficiency of the complete window and frame to produce a single number. It's based on a similar European Union System for domestic appliances and is a simple way to compare the energy efficiency of competing products.
Pilkington energiKareTM helps windows achieve high levels of energy efficiency, a minimum C rating.
