A Rated Windows The Government approved Window Energy Ratings scheme rates windows on a scale from G being the lowest up to A+ being the most energy-efficient windows. The current building regulations concerning the energy efficiency of homes require that windows are a minimum of band C however most window companies are aiming to provide the ...

Energy-efficient glazing is the term used to describe the double glazing or triple glazing used in modern windows in homes. Unlike the original single glazing or old double glazing, energy-efficent glazing incorporates low-emissivity coated glass to prevent heat escaping through the windows.

Window Energy Ratings. The Window Energy Rating (WER) tells you how energy-efficient your windows are. The rating system is based on a scale of G to A+, with A+ windows being the most energy-efficient. The scheme is similar to those seen on household appliances, white goods and light bulbs.

Its ubiquity is a result of the range of new technologies that mean it can be used for much more than just windows and conservatories. Innovations in coatings mean glass can be given a range of beneficial properties like thermal insulation, as well as solar and noise control. One of the most popular – but perhaps misunderstood – properties ...

Low-emissivity glass (or low-e glass as it is commonly referred to) is a type of energy-efficient glass designed to prevent heat escaping through your windows to the cold outdoors. Low-e glass such as Pilkington K Glass™ or Pilkington Optitherm™ has an invisible coating which dramatically reduces heat transfer and reflects interior heat ...

Pilkington Texture Glass, a rolled patterned glass with one surface having a specific pattern or design impressed into the surface, offers a wide choice of attractive designs.

If the thought of spending endless hours cleaning windows puts you off building a new conservatory or installing skylights then self-cleaning glass is precisely what you need. View this demonstration video to gain a better understanding of how self-cleaning glass works with the forces of nature to keep your glass cleaner. How it works

Replace your glass, Reduce your heat loss Reduce the amount of heat lost through windows in your home by up to 75% - by installing Pilkington Insulight™ Therm units containing energy-efficient glass.. Providing your existing frames are still in good condition, you only need to replace the glazing to see a huge improvement on the energy efficiency of your home.

There are less cold draughts from convection near the windows and the risk of condensation on the glass is reduced. In this way, low-e glazing not only prevents heat loss, but also encourages warmth during the colder months of the year. U g-value of energy-efficient glazing.
