This unusual square and squinted bay window presented 2 challenges for us. The first was the condition of the existing sashes. The second was that the bay itself had subsided in the past by up to 3 inches, causing the sashes to become pinched and deformed under the bay’s weight.
Now that the subsidence had stabilised, we decided to approach the problem by making new pressure treated pine sashes. Pressure treatment gives the bare wood 30 years resistance to rot and a 10 year-life paint system ensures the wood won’t become bare any time soon. We took the opportunity to fit super-insulating, argon filled double glazed units in the new sashes to keep heating bills down as well as road noise.
To overcome the problems caused by the subsidence in the bay, the sashes were made with extra thick top and bottom rails. It was then possible to hang the sashes on the original 120 year old hinges and “Shoot in” each sash to exactly fit the subsided frame. By doing this, we able to restore the windows to fully functioning without resorting to an extremely costly and disruptive bay window replacement!
