Energy saving Planitherm glass is the most energy efficient available. Its advanced coating technology reflects radiated heat back into your home, instead of letting it escape through your windows. Planitherm also allows the free heat and light from the sun to pass through the glass to the inside your home. Resulting in a Lighter, brighter, warmer and more energy efficient home.
(Energy Saving Trust) ~ "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"
All our windows are installed with Planitherm Glass and Pilkington patterened glass
Planitherm helps to virtually eliminate internal condensation and reduce cold spots in and around windows
