Flush casement windows
A clean, elegant and sleek uPVC window frame.
What is a flush casement window?
When closed the sleek profile of a flush sash casement window sits flat within the frame. Whereas a standard casement window sits slightly proud and has a lip over the frame.
Timeless timber aesthetics
The sleek profile sits flush into the frame giving the appearance of a traditional timber window.

Perfect for conservation, heritage and listed buildings
At Yorkshire Windows, we understand that many property owners require the charm of a traditional timber window frame due to planning or environmental restrictions. However, we also recognise the challenges that come with timber frames - they can be expensive, require regular maintenance, and are difficult to replace.
Our flush casement windows have been thoughtfully designed to replicate the classic look of traditional timber frames while offering a range of benefits that cater to modern living.
The aesthetics of wood, with modern advantages
Our uPVC flush sash casement windows can be expertly foiled to look like authentic timber or provide a sleek, contemporary finish, all while offering the benefits of safe, secure, efficient, and great-looking windows and doors.
You get the best of both worlds - the timeless beauty of timber and the practicality of advanced window technology.
Superior energy efficiency and cost savings
Our flush sash windows are capable of achieving A+ WER (Windows Energy Ratings) with cost effective double glazing – and a U-value as low as 0.8 W/m²K (with triple glazing).
These upgrades offer significant thermal benefits, making them the best alternative to traditional timber windows. Not only do you get the aesthetics you desire, but you also enjoy enhanced insulation and potential cost savings on energy bills.
