Flush sash windows, often referred to as flush casement windows, offer a stylish, timeless solution for homes. Their slim sightlines and flush fit into the window frame recreate the style of centuries before making them an ideal alternative to timber casement windows. They are a popular option for window replacements in conservation homes and those looking for a more traditional look with the advantages of modern window technology.
Flush casements themselves aren’t new, and they date back to the 19th century, with examples evident in late Georgian, Victorian and Edwardian buildings. Where flush sash windows come out far ahead of their predecessors is their energy efficiency, durability, security, along with a host of other advantages. Available in double glazing and triple glazing, you can customise the thermal performance and choose from a range of finishes, colourways and accessories for the perfect bespoke window.

Frequently Asked Questions
What is a flush sash window?
Flush sash windows are easily identified by the sashes that finish flush with the window’s external face. When the window is closed, the sash will be level with the outer frame which creates a smooth, even finish. These uPVC windows replicate the look of traditional timber frames but have a number of performance advantages, making them a better choice for most projects.
While mimicking the aesthetics of traditional casement windows, these windows are ready for the challenges of modern life thanks to improved thermal efficiency, excellent security, and unmatched durability.
Why choose uPVC flush sash windows?
uPVC flush sash windows offer better energy efficiency than other materials. In addition to keeping damp and cold out, the plastic frames also effectively retain heat. These superior insulating properties make them a more environmentally friendly alternative to timber frames. They are also significantly more cost-effective, longer-lasting and easier to look after.
Fuss-free, durable uPVC flush sash windows require little maintenance, and the authentic design details make them a popular choice for heritage homes and contemporary new homes alike.
Are flush fit windows different to storm proof windows?
Flush-fit is another way to describe flush casement or flush sash windows. They fit flush into the window frame for a simple, elegant design. This flush fit makes them different to storm proof windows that overlap the frame.
Are they more expensive?
uPVC windows are more affordable than timber and aluminium alternatives and have a significantly longer lifespan making them the best long-term choice. If you compare conventional casement windows to those with a flush design, the price difference is negligible.
