Flush Sash Windows
The design of flush sash windows takes inspiration from traditional timber joinery, allowing the sash to sit flush in the frame. They are ideal for homeowners looking to bring a traditional charm to their home.
Timeless Aesthetic, Contemporary Advantages
Flush sash casement windows offer the realism of traditional pre-1932 timber windows combined with 21st Century energy-saving benefits and low maintenance.
Many homeowners require a traditional timber-style window, either for aesthetic reasons or due to planning or conservation restrictions. Liniar’s uPVC flush sash casement windows can be foiled to look like traditional timber or to offer a sleek, unobtrusive finish.
Flush Sash Window Options
Unlike standard uPVC casement windows, flush sash windows have no external overlap - the sash fits flush into the outer frame, just like a timber window.
For even greater realism, flush sash windows can be mechanically jointed instead of welded. Combined with a woodgrain foiled finish, they can be difficult to distinguish from wooden windows.

Innovative Approach
Designed and tested in our purpose-built factory in the heart of the UK, the Liniar range of windows and doors is celebrated for its impressive energy efficiency. What you may not know though is that Liniar doesn't manufacture finished glazed products.
Using cutting edge technology and machinery, Liniar extrudes lead-free uPVC frames and other components, distributing them to a nationwide network of independent, specialist window fabricators. These fabrication experts manufacture Liniar flush sash windows to your exact specification.
Flush Sash Window FAQs
Are uPVC flush sash windows cheaper than traditional timber windows?
Traditionally crafted timber windows can be expensive to manufacture. The high purchase cost of timber, combined with the ongoing annual maintenance costs of sanding, staining or painting, means Liniar's flush sash windows may be a more cost effective solution over the life of the windows. Don't forget to compare the energy savings you can make for your home by installing uPVC flush sash windows instead of timber, too!
Can flush sash windows be installed in homes that are listed properties or located within a conservation area?
Under the direction of the English Heritage organisation, properties which are grade listed in conservation or historical areas are bound by a different set of planning permissions. In the past, windows and doors which were made of modern materials wouldn't gain approval through Article 4 and Listed Building Consent, but with the advances in window technology, some councils are taking a more modern approach.
uPVC flush sash windows replicate the historical timber windows found on period properties with the added benefits of thermal and energy efficiency and therefore more councils are open to approving them for installation. If you live in a listed property or conservation area, always check with your local council and obtain the necessary Planning Permission from the Local Planning Authority before beginning any work on your property.
Is specialist equipment required for the installation of Liniar flush sash windows?
No, Liniar flush sash window systems have been designed to be installed in exactly the same way as standard Liniar uPVC casement windows, using the same innovative glazing platforms to ensure the correct weight-bearing and drainage.
If I choose a foiled finish for my Liniar flush sash window, will anyone be able to tell it's not made of wood?
Foils are carefully applied at the manufacturing stage by Liniar, using state-of-the-art machinery. Laminated foils can be applied on both inside and outside, or you can keep the interior plain white to match your home furnishings.
When 70mm flush sash windows are opened, you may be able to see the white or coloured uPVC profile on the inside of the frames, but when closed they offered a perfectly realistic alternative to timber.
If you choose matching internal and external foils and require the woodgrain effect to run all the way through, even when the windows are open, choose the 80mm flush sash Resurgence window system, which features foiling on the inside too.
What distinguishes flush sash windows from standard casement windows?
Flush sash windows have a sleek design where the sash aligns flush with the frame when closed, offering a seamless appearance. They complement diverse home styles, spanning modern to traditional and catering to your aesthetic preferences and architectural needs.
