Resurgence Flush Sash

New for 2019, Liniar’s Design and Development team have reinvented the flush sash window with the introduction of Resurgence. Designed using patented features like the Liniar co-extruded bubble gasket, in tandem with a double rebated weather seal, make Resurgence ultra energy efficient, as well as providing a stunning appearance.

Offering an authentic ‘timber appearance’ design with optional features such as mechanical jointing and Georgian Bars, the Resurgence uPVC flush sash window looks the part without the extra maintenance required with a traditional timber window.

Safe, Secure and Stunning

Resurgence has been thoroughly tested and accredited with PAS24 Enhanced Security, Secured by Design and Part Q, giving homeowners peace of mind that their windows are totally secure.

Designed to match the rest of the Liniar range of products, including bi-folding, patio and French doors, and conservatory and lantern roofs, Resurgence features fully foiled glazing areas to both the other frame and transom profiles, adding a touch of authenticity – even when the window is open.



Like traditional timber flush sash windows, Resurgence is a 70mm sash within an 80mm frame – eliminating the telltale overlap typically seen in standard PVCu windows. With a wide colour range available from stock and special orders on longer lead times, property owners can add a punch of colour to their exterior or go with classic character in white.

What’s the Difference?

Flush uPVC windows often require brush piles to be inserted at the fabrication stage, or feature visible external seals; however Liniar’s Design and Development team have created Resurgence with aesthetics in mind, removing unsightly seals that can be seen in the shadow gap.

Now, the unique double rebate formed with Liniar co-extruded gaskets is located around the back of the sash, leaving the shadow gap clear. This gives Resurgence its beautifully clean, tidy appearance.

Offering a 70mm sash within an 80mm frame, Resurgence is unlike other timber-replica style uPVC windows. It has been designed to be installed in exactly the same way as a standard PVCu window, meaning no special training is required for installers, and less time and disruption for the homeowner.

With a wide range of foiled finishes available from stock (and special colours on longer lead times), homeowners will be able to create a traditional or a modern appearance to suit most property types.

Article 4

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 than newer properties. According to Historic England, conservation areas exist to protect architectural and historical places of interest.

Properties which are under Article 4 distinction – this means that some work which typically doesn’t require planning permission would in a conservation area.

This includes replacing windows, doors, downpipes and gutters. For listed buildings, it would additionally require Listed Building Consent.

In the past, windows and doors which were made of modern materials wouldn’t get approved through Article 4 and Listed Building Consent, but with advances in window technology over recent times, some councils are taking a more modern approach.

Resurgence replicates the historical timber windows found on historical properties with the added benefits of thermal and energy efficiency, making more councils open to allowing them.

If you live in a listed property or conservation area, check with your local council and obtain the necessary Planning Permission from the Local Planning Authority before beginning any work on your property.
