RAD provide a comprehensive range of Pilkington Glass
products including double glazed units using 'K' glass and
the latest product from Pilkington, energiKare™ which
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 . .
and 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,
and Pilkington Optiwhite™, a special 'extra-clear' type of
glass which increases the degree of solar heat gain making
your home feel warmer without the need to turn up heating.
