Lower your energy bills by installing Vista-Therm in your replacement windows – proven to be the most energy-efficient window glass available in the UK.

Vista-Therm is a new generation of energy saving window glass that uses advanced coatings to retain more internal warmth whilst capturing free energy from natural daylight. That means lower energy bills compared to standard windows.

Using Vista-Therm as a good reference for your window installation quote should be able to give you window quote for A rated windows using the frame of your choice, for around the same cost as less energy efficient windows.

If you are planning to replace your existing single glazed or double glazed windows, and you want the best possible choice for energy savings, ask your installer for Vista-Therm.

Insist on Vista-Therm for a warmer home and lower energy bills.

 

What Is Energy Efficient Glass?

A staggering 26% of all domestic heat loss escapes through the windows*. Installing energy efficient windows can save you up to 28% per year on your heating bills compared to traditional windows and frames so it is very important that when looking for a upvc window quote or prices you ask about the Energy Efficiency of the products.

Research has shown that many homeowners assume that all double glazing is equally energy efficient. In fact, there are huge differences in performance and it is the glass that makes the difference.

Vista-Therm is a new generation of energy saving window glass and the most energy efficient double glazing available. Its advanced coating technology reflects radiated heat back into the room, rather than allowing it to escape through the windows. At the same time, Vista-Therm allows free heat and light from the sun to pass through the glass.

The result? – Lighter, brighter, warmer and more energy efficient homes thanks to the advanced thermal insulation of Vista-Therm which is 3 times more efficient than single glazed units and at least 25% more efficient than most currently installed double glazing.

About Celsius Performance Glass

More consumers are becoming increasingly aware of the benefits of glass roofing compared with polycarbonate. Aside from aesthetics, glass tends to have a much longer life span compared to other roofing products and coupled with the ease of maintenance, it is now a preferred option by many discerning consumers.
 
The Celsius range was one of the first glazing options on the market to offer the unique combination of heat reflection AND thermal insulation, but Celsius has even more benefits.
 
Rainfall and traffic noise are dramatically reduced when compared to 25mm polycarbonate. The argon gas filled units reduce the noise even further as well as offering greater insulation properties.
 
With our Celsius One and Celsius Elite products, destructive UV rays are reduced by up to 88%, thus offering protection for furniture and fabrics from sun damage. Additionally Celsius Clear, with its neutral tinted appearance for side frames and certain roof installations, makes the Celsius range the complete performance glazing solution.

  • Does not support adhesion or growth of bacteria, for a more hygienic environment.
  • Protects the surface from organic and inorganic contamination.
