Today we installed the new bathroom window, and true to the retrofit mantra of doing it once and doing it right, the window is made from Accoya timber so is dimensionally stable and will last perhaps 60 years plus, the glazing is triple with krypton gas to reduce sash thickness, high performance airtight seals all round, concealed balances within the sashes (which are not visible at all) and reduce air leakage and cold bridging. This is a window developed over 2 years for another project and should be rolled out to the retrofit market! Manufacured by Westgate Joinery. Period detailing to match existing windows and you really can’t tell it’s super high performance. Beautiful installation of expanding foam airtightness to the frame.
