UPVC Flush Sash Windows

The Charm of Timber. The Strength of Modern Engineering.

Our flush sash uPVC windows offer the traditional charm of timber frames with none of the upkeep. Designed with sashes that sit flat within the frame, they create a heritage-style appearance suited to period homes, conservation areas and modern builds looking for elegant simplicity. Backed by advanced energy efficiency, flush sash windows are ideal for homeowners who value both authenticity and performance.

Multi-Point Locking

Security starts at the window. Our uPVC casements come fitted as standard with heavy-duty multi-point locking — securing the frame simultaneously at multiple points for protection no single lock can match. Optional fire escape hinges add further peace of mind, allowing full opening in an emergency without compromising everyday security.

Thermally Efficient Frames

Keeping warmth in and noise out starts with the frame itself. Our uPVC flush sash windows feature multi-chambered insulated frames, A rated for energy efficiency — delivering exceptional heat retention that reduces energy bills and a quieter home that filters out the noise of everyday life.

Your choices and options available

UPVC Profile Options

Colour and Finish Options

All glazing uPVC windows and doors are available with a choice of two high-quality profile styles — giving you flexibility to match both traditional and modern properties. Each option delivers the same robust performance and thermal efficiency, but offers a different visual finish.

Colour and Finish Options

Available in a carefully selected collection of contemporary and traditional foil finishes, each uPVC product can be customised to match both exterior character and internal decor. Dual-colour options allow for aesthetic flexibility — for example, an Anthracite Grey exterior may be paired with a White interior to maintain a light, modern feel indoors.
