Pilkington K glass

How Pilkington K Glass™ makes double-glazing more effective.

When building a new conservatory, consider Pilkington K Glass™. It makes double-glazing as effective as triple glazing and cuts fuel bills. Just the kind of breakthrough you might expect from a company that's been leading the way in glass technology for 172 years.

How Pilkington K Glass™ works.

Pilkington K Glass™, which usually forms the inner pane of a double-glazing unit, allows less heat to escape through your windows than ordinary glass. Thanks to a special energy saving coating which lets the sun's rays through, but reflects heat from fires and radiators back into your home. Heat which ordinary double-glazing allows to escape. A diagram of this can be seen here.

Increased comfort.

The unique properties of Pilkington K Glass™ mean you can turn down your thermostat and still remain just as comfortable. This can result in savings.

Reduced condensation.

Pilkington K Glass™ also significantly reduces unsightly internal condensation. Condensation forms when warm, moist air comes into contact with a cold surface, such as conventional glass. The energy saving coating on our glass actually makes the surface warmer to the touch, so condensation is reduced.

Eliminates cold spots.

Ordinary glass offers poor insulation; so uncomfortable cold spots close to windows are a common problem. Double-glazing can alleviate this to an extent, but only double-glazing with Pilkington K Glass™ has the total solution. It provides superior insulation, making the inner pane of your window much warmer. This eliminates cold spots, and increases useful floor space.

Perfect for conservatories.

Better insulation and no cold spots near windows makes Pilkington K Glass™ perfect for conservatories. In fact, it will typically keep an unheated conservatory comfortable for a greater part of the year than ordinary double-glazing allowing you to make the most of your conservatory all year round. Pilkington K Glass™ can also be toughened or laminated for safety and greater security.

Help the environment.

By reducing the amount of heating needed to keep your home warm, Pilkington K Glass™ helps to save energy and vital natural resources. In fact, if all the single glazed buildings in the United Kingdom were double glazed with Pilkington K Glass™ it would save £600 million worth of energy per year. That's enough energy to heat every house in six cities the size of Birmingham. Add this to smaller heating bills, a warmer home and reduced condensation and Pilkington K Glass™ is clearly the best glass for double-glazing.
