Description

Heritage casement windows perfectly echo the smooth, traditional styling of historic windows. They are ideally suited for refurbishment contracts and listed buildings. They include traditional putty and are offered in a choice of hardwood and softwood frames, with RAL finishes.

Single or double Slim Sightline glazing means these casement windows deliver both historic styling and modern thermal and acoustic performance. Available as inward or outward opening, side-hinged or top-hung.

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