With energy bills are on the increase, environmental concerns higher on the agenda than ever before and building regulations becoming more demanding every year, choosing a window system that offers higher Windows Energy Ratings for a lower cost is a must.
With our lead-free, multi-chambered profile, patented co-extruded bubble gasket, glazing flipper and thermal dam, you don’t need expensive triple glazing to achieve the highest energy ratings – our system achieves an energy rating of A+ with ease and a U-value of 1.2 with cost effective double glazing.
The uPVC profile, or frame, in our windows contain symmetrical chambers to minimise the transfer of heat from the inside of your property to the outside. This, together with other innovative design enhancements, helps to minimise energy costs on an ongoing basis.
Can’t praise JJ Harrisons enough, they really went the extra mile and our windows are amazing. Thank you!
