Heritage Sash Windows
Our heritage sash windows are made to match box sash windows crafted more than a century ago. These premium sash windows, with the classic weight-and-pulley mechanism are the perfect choice for replacement windows in listing buildings, while also suiting high-end architect-led new developments.
We use traditional putty externally to secure high-performance Slimlite glass. Single or double glazed, this authentic-looking slim glass satisfies the modern demands for acoustic and thermal performance.
Solid glazing bars come as standard, so each window comprises a number of individual glass panels, giving these heritage sash windows genuine character.
