Traditional appearance with modern performance
Flush Casement Windows
Flush casement windows combine the classic look of traditional timber windows with the practical benefits of modern materials. The opening sash sits flush within the outer frame, creating a smooth, flat external finish that suits both period properties and contemporary homes. Available in uPVC, aluminium and hardwood most people prefer to purchase aluminium or uPVC flush casement windows due to the significant cost savings and lower maintenance required.
They are designed to offer improved comfort, security, and durability compared to older window styles. With a wide choice of colours and woodgrain finishes, they provide a versatile window solution for renovations, replacements, and new-build projects.
Waveney Windows supplies and installs flush casement windows for homes across Suffolk, Norfolk and beyond, offering practical advice and professional fitting to ensure reliable long-term performance.
What Are Flush Casement Windows?
Flush casement windows are defined by their sash sitting level with the surrounding frame when closed. Unlike standard stormproof casement windows, which overlap the frame, flush designs create a uniform external appearance.
This window style takes inspiration from traditional timber casements commonly found on cottages and period homes. Modern uPVC and aluminium flush systems recreate this appearance while offering improved insulation, weather resistance, and security.
Flush casement windows are well suited to:
- Period and heritage-style properties
- Homes where traditional appearance is important
- Contemporary properties seeking clean lines and minimal detailing

Frequently Asked Questions
What are uPVC flush windows and how do they differ from standard casement windows?
uPVC flush windows, also known as uPVC flush sash windows or flush fit windows, are designed so the opening sash sits flush within the window frame when closed. This creates a flat, flush appearance compared to standard casement windows, which overlap the frame. Flush sash window styles are often chosen for their traditional aesthetics and suitability for period properties.
Are flush sash windows suitable for traditional properties?
Yes. Flush sash casement windows are commonly selected for traditional properties such as Victorian windows, cottages, and older homes where original features are important. Their flush appearance closely reflects traditional timber casement windows, offering traditional charm with a modern twist using durable uPVC or aluminium window materials.
What colour options are available for flush casement windows?
Flush casement windows are available in a wide range of colour options, including classic white, period colours, anthracite grey, sage green, and traditional woodgrain finishes such as golden oak. Dual colour options are also available on some systems, allowing different colours inside and out to suit both interior décor and exterior style.
Do flush casement windows allow as much light as other window styles?
Yes. Flush windows use large glass panes within slim window frames to maximise natural light. Fixed flush windows and opening sashes can be combined to suit different elevations, while decorative glass, coloured glass options, or Georgian bars can be added where style or privacy is required.
Are flush casement windows energy efficient?
Modern flush double glazed windows are designed to reduce draughts and improve comfort compared to older window styles. Improved seals and quality glazing help support better energy performance and can contribute to lower heating costs when replacing older windows. Double glazing is standard, with triple glazing available in some configurations.
