Pilkington UK has launched Pilkington K Glass A, a low-e, hard coated glass, which helps windows to achieve a Window Energy Rating (WER) A rating when installed within a suitable frame.

When used as the inner pane of an insulating glass unit, and combined with Pilkington Optifloat or Pilkington Optiwhite, a U-Value of 1.4 W/m2K can be achieved.

This exceeds the latest energy-saving building regulations when installed within a suitable window frame.

Pilkington K Glass A is a durable, single-stock coated glass that can be used in both annealed and toughened formats and is easily stocked, processed and installed.

Suitable for both commercial and residential settings, its high light transmission maintains neutrality and avoids the grey appearance of other hard coated low-e products on the market.

Kristian Chalmers, Product Manager, said: “Pilkington K Glass is the UK’s leading thermal glass brand and the launch of K Glass A enables us to ensure we continue to provide customers with the highest quality products, while meeting the increasing market demand for energy-efficient glazing.

“Pilkington K Glass A is the ideal choice when it comes to reducing energy consumption, as it helps to decrease the cost spent on heating a building as less energy is needed to maintain a comfortable temperature.

“Not only this, it also reduces internal condensation and enables designers to extend the glazed area of a building without increasing heat loss.

“The Pilkington K Glass brand has been established for more than 20 years and this latest development provides customers with an option for enhanced performance, ensuring our products continue to be a trusted solution for meeting energy-efficiency requirements for years to come.”
