Flush sash windows
Traditional character without timber maintenance.
Flush sash windows combine balanced, timber-inspired proportions with the everyday performance of a modern uPVC system.
01
Designed around the opening
A flush sash is made for the confirmed opening with the exterior face of the opener sitting level with the outer frame. Careful sizing helps retain the flatter, timber-inspired proportions that define the style.
02
The complete specification matters
Frame depth, joint treatment, foil, glazing bars, hardware and drainage details influence authenticity. We distinguish the Liniar standard flush option from the deeper Resurgence system in the quotation.
- Made to measure
- Clear specification before manufacture
- Supply only or local installation
03
Supply only or professionally installed
Photographs and a survey are particularly useful on older properties where stone, render, cills and existing linings are rarely perfectly uniform. Planning or listed-building requirements remain the property owner’s responsibility.
Planning and specification
What to consider when choosing flush sash windows with traditional character
A good quotation begins with the property and the way the opening will be used. We look at joint style, woodgrain finish, glazing bars, hardware, drainage and the required frame depth. The best answer is not always the same for every room, so it is worth considering privacy, daylight, furniture positions and how often an opening will be used before settling on a specification.
Master Plastics can discuss Liniar flush sash and Resurgence-style options for older and contemporary homes. We manufacture made-to-measure products in Bristol and can provide supply only or professional installation across Bristol and nearby areas, depending on the project. Installed work is surveyed before manufacture; supply-only customers remain responsible for confirming their order sizes and fitting requirements.
From first enquiry to finished order
Close photographs of existing joints, glazing bars and surrounding stone or brick help when the aim is a traditional appearance. We also need to know whether the property is listed or in a conservation area.
The original Liniar flush sash and the deeper Resurgence system are not identical products. The quotation will name the selected system, finish, joint treatment, glass and hardware so the appearance and performance are clear.

Questions about flush sash windows
What does flush sash mean?
The opening sash sits level with the outer frame on the exterior, creating flatter proportions than a conventional overlapping casement. Foiled finishes and considered joint details can strengthen the timber-inspired appearance.
Are flush sash windows suitable for older houses?
They can suit many period and character properties, but conservation areas and listed buildings may require consent or a particular material and detail. Planning requirements should be checked before ordering.
What is the difference between standard flush sash and Resurgence?
Liniar’s original flush sash uses a 70 mm frame, while Resurgence is an 80 mm double-rebated system with additional joint and glazing choices. We can explain which options we currently manufacture and quote.
