Flush Sash Windows

The attractive, low maintenance and thermally efficient timber alternative.

Perfectly Designed

50mm x 62mm single rebated sash design sits snugly in the 70mm outer frame.


Manufactured using multi-chambered uPVC Liniar profile for optimum thermal efficiency.

Tailored to You

Customise our flush sash windows with key-locking monkey tail handles and dummy stays.

Yale Locking

Yale shootbolt locking windows are covered by a money-back promise in the event of a break-in.

Low Maintenance

The traditional look of timber without the maintenance. You’ll never need to sand, treat or paint them.

Liniar Profiles

The most technically advanced uPVC profile system in the UK is guaranteed to enhance any home.

Glazing flipper

Unique ‘glazing flipper’ reduces cold transfer, water ingress and noise pollution.


Size-optimised chambers break up mini convection currents locking in pockets of warm air.

Superior gaskets

High performance (patented) double-action ‘bubble’ gaskets maintain tight weather seals.

Integrated reinforcing

Internal structures provide exceptional stiffness & rigidity whilst minimising the need for steel reinforcing.

Positive drainage

Specially designed profile contours maximise natural drainage and prevent moisture build-up.

Thermal dam

Designed to Passivhaus recommendations, the thermal dam reduces heat transfer.

Beautiful Asethetics

The frame and sash sit flush when closed, recreating the look of traditional timber joinery. Our Flush Sash Window incorporates a dedicated slimline sash, allowing the face of the profile to sit flush with our existing 70mm Energy Plus outer frame.

The Flush Sash Casement Window gives you that traditional timber appearance, whilst still being ultra-low maintenance and 100% recyclable.
