Timber Casement Windows

Can you tell
the difference?

Timber casement windows are one of the most popular window styles in the UK. They’re easy to use and allow for optimum airflow for great temperature control. The challenge is that listed buildings are required by law to maintain the original look as much as possible.

Our heritage timber casement windows perfectly echo the smooth, traditional styling of historic windows. Where possible, we help with restoration, but our replacement windows are styled to be so true to the original design that nobody can tell the difference.

Traditional style requires
traditional thinking
and modern materials

TRC timber casement windows boast time-honoured details, including traditional putty, and are offered in a choice of hardwood and softwood frames (plus RAL finishes).

Single or double Slimlite glazing means our windows deliver historic styling and modern thermal and acoustic performance. This will allow you to benefit from a warmer, quieter home and lower energy bills, eliminating draughts for good.

All of our heritage windows (including our heritage timber sash windows and timber period doors) are available in a range of colours and finishes to fit with your original and existing style and are available inward or outward opening, side-hinged or top-hung. Our heritage casement windows also include child safety catch-type restrictors, depending on your preference. Precision design is a guarantee.

Elegant, simple, timeless and highly efficient, our bespoke range of timber casement windows is the go-to choice for builders and architects working on heritage projects across the UK. We are experts when it comes to restoring windows in period, conservation and listed properties, including windows for Georgian, Edwardian or Victorian buildings and homes. We can take you through the whole process, from design and survey to manufacture and installation.

For non-listed buildings, see our collection of traditional timber casement windows and doors, including box sash windows, spring sash windows, tilt and turn timber windows and timber sliding doors.
