Shaped windows
At CG Windows we specialize in crafting timber windows and doors for period, listed, and conservation properties, we also expertly craft bespoke shapes—including bowed, curved, and arched sash windows—that faithfully replicate your originals.
From Gothic arched sash and casement windows to ‘bicycle wheel’ curved sashes and elegant bowed bay windows, shaped timber windows and doors have long been a defining feature of British architectural heritage.
We offer full replacement, partial replacement, or restoration of curved and arched sash windows and doors—ensuring every detail remains true to the unique character and history of your property.
