Neutral Low E (1.1 u value) double glazed units as standard
At Leivers & Millership we use Neutral coloured Low E soft coated heat insulation glass on all our double glazed units. These are 28mm overall sealed units with 4mm float glass and a 20mm argon filled gap achieving a u value rating of 1.1  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.
