What Are Flush Casement Windows?

View our Projects

Flush casement windows are a style where the opening sash sits completely flush with the outer frame when closed — giving a beautifully clean, flat appearance that is ideal for period Cornish cottages, conservation areas and traditional properties across St Austell and the surrounding area. Unlike standard casement windows, where the sash projects slightly forward of the frame, flush casements have a seamless face that closely replicates the look of traditional timber windows without any of the maintenance. Available in uPVC and aluminium, in a wide range of woodgrain and solid colours, flush casements are increasingly popular across St Austell, Fowey, Lostwithiel and Padstow.

Our uPVC flush casement windows combine the traditional appearance of timber with the thermal efficiency, security and low maintenance of modern double glazing. Available in woodgrain finishes including golden oak, rosewood and Irish oak, as well as a wide range of solid colours to complement any Cornish property.
For an ultra-slim, contemporary flush appearance — our aluminium flush casement windows are thermally broken for year-round comfort and available in any RAL colour. The perfect choice for modern renovations and self-build projects across St Austell and the surrounding area.
Flush casement windows are often the preferred choice for properties in conservation areas, AONBs and near listed buildings across St Austell and the surrounding area. Their traditional flat-faced appearance closely replicates original timber windows while meeting all current building regulation and thermal performance standards.
Our flush casement windows are available in a comprehensive range of woodgrain foils — including golden oak, rosewood, Irish oak and Chartwell green — as well as solid colours, dual-colour options and smooth white finishes, giving you complete design flexibility.
