Energy-Efficient Glass


Don’t throw your money out of the window!

Choosing the right window glass can have a big impact on the amount of energy you use…and on your heating bills!

Did you know that around 25% of the heat in your house escapes through your windows? 

Having energy-efficient glass in your windows will help to save energy and reduce your household heating bills.  The good news is that by using the right type of glass, you can also let more free heat from the sun come in and, at the same time reflect more heat back inside your room.

Many people think that by having any double glazing, they are protecting themselves from heat loss through their windows.  Sadly this is not always true.  Although all double glazing offers a degree of energy efficiency, Pilkington energiKare™ energy-efficient glass can be more than twice as energy-efficient as older double glazing with no low-e coating and small air spaces.

To give you more figures, by replacing your single glazing with Pilkington energiKare™ energy-efficient glass, you could reduce the amount of energy lost through your windows by up to 75% and reduce your heating bills by up to 20% every year.  That means that if you have a typical semi-detached house, you could save up to £7000 over the lifetime of the windows. 

Just think what you could do with that money!

Why choose Pilkington energiKare™ energy-saving glass?

In recent years, a number of such products have been introduced to the UK market. These include glass such as Planitherm which is now used quite extensively, but the most well-known product is Pilkington K Glass™. This product was introduced some time ago but is still extremely popular with window manufacturers and homeowners alike.

Pilkington energiKare™ double glazing units contain both Pilkington K Glass™ (an energy-efficient glass) and Pilkington Optiwhite™ (a special low-iron glass).  Each has its own unique role in saving you money by maximising energy efficiency in your home.

  • Pilkington Optiwhite™ makes up the outer pane of the insulating glass unit.  It is an "extra clear" glass allowing more sunlight and solar heat to enter through your windows and into your house.
  • Pilkington K glass™ is the UK’s best-selling low-emissivity glass and makes up the inner pane of the insulating glass unit.  This special energy-saving glass functions primarily to stop heat escaping through your windows and helps to retain heat in your home.

* The Window Energy Ratings Scheme is a grading system similar to the efficiency grades you find on white goods and other household appliances.  Window Energy Ratings are based on a scale of A to G, where A-rated windows are the most energy-efficient.
