What are UPVC casement flush windows?
uPVC flush casement windows are designed so that the window sash sits perfectly level within the outer frame — creating a smooth, flat appearance. This “flush” look mirrors traditional timber windows found in period homes, while offering all the benefits of modern uPVC: superior insulation, security, and low maintenance.
We manufacture our flush casement windows using the Deceuninck profile system, renowned across the UK for its precision engineering and premium quality. The result is a window that combines heritage charm with 21st-century performance.

Benefits of uPVC flush casement windows
How do flush casement windows compare to traditional casement windows?
Traditional casement windows have a “lipped” sash that overlaps the frame. Flush casement windows, on the other hand, close neatly into the frame, sitting completely flat. The difference may seem subtle, but visually it’s striking — delivering a neater, more refined look.
Designed for every home
Every window we manufacture is made to measure and tailored to your property. Choose from:
A wide range of heritage woodgrain finishes and contemporary colours
Dual-colour frames (different inside and outside)
Decorative glazing and astragal bar options
Traditional or modern handles and hardware
Whether you’re renovating a Victorian terrace or designing a new-build, we can create the perfect match for your home’s character.
Energy ratings, sustainability and performance
As part of our commitment to sustainability, Ada Windows recycles all uPVC, aluminium and glass waste generated during manufacturing. Our flush casement range achieves exceptional thermal and acoustic performance, helping homeowners reduce carbon footprints while enhancing comfort.
