Description

Heritage sash windows constructed to match box sash windows crafted more than a century ago. The sash windows, with the classic weight-and-pulley mechanism, are a suitable choice for replacement windows in listing buildings, whilst also suiting high-end architect-led new developments.

Traditional putty is used externally to secure high-performance Slim Sightline double glazing. Available single or double glazed, the authentic-looking Slim Sightline double glazing has good acoustic and thermal performance. Solid glazing bars are supplied as standard.

Bespoke windows and doors are available; consult manufacturer for details.
