Victorian sash windows are characterised by their taller proportions, often featuring a two-over-two or six-over-six glazing bar pattern, ornate sash horns, and deeper box frames to accommodate the weight-and-pulley system.
Built predominantly between 1837 and 1901, they typically used cylinder glass set in linseed oil putty within softwood or hardwood frames. Today, authentic restoration-using traditional joinery, draught-proofing, and heritage-compatible double glazing-preserves their historic charm while improving thermal efficiency and operation for modern living.
