Why Planitherm glazing saves property owners energy

According to the Planitherm.com website “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. Research has shown that many home owners 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.”

The specification of all sealed units installed by Hazlemere Window Company Ltd in High Wycombe includes Planitherm Total+, a high very high quality glass coating that improves the performance of double glazed and triple glazed sealed units. As their website explains “Planitherm is a new generation of energy saving window glass and the most energy efficient 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, Planitherm allows free heat and light from the sun to pass through the glass.”

The result of this technology is lighter, brighter, warmer and more energy efficient homes, which according to Planitherm themselves “is 3 times more efficient than single glazed units and at least 25% more efficient than most currently installed double glazing. Planitherm glass uses advanced coating technology to capture free energy from natural daylight called solar gain to help heat UK properties. The advanced coating reflects heat back into the room, meaning less energy is needed to heat any property fitted with thermally efficient glazing such as Planitherm to the desired temperature.”

“Planitherm helps fenestration system achieve their optimum energy ratings as the product combines with virtually any window frame to achieve a Window Energy Rating (WER) of C and its unique properties mean an “A” rating is easier to achieve. Planitherm maximises the amount of natural light into the home, without the haze or tint effects associated with some older double glazed windows. Planitherm helps to virtually eliminate internal condensation and reduce draughts and cold spots in and around windows.”

It is not just the glass that makes a double glazed or triple glazed window or door energy efficient, it is the quality of the energy rated window system, warm edge spacer bar, gaskets and standard of installation. The important thing for UK property owners is to get the best possible combination of system, glazing and fitting, as this is what really helps home owners save energy and therefore reduce heating bills.
