Classic Flush Style
Flush sash windows combine the elegance of period-style timber with modern manufacturing and materials. Unlike standard casement windows, the sash closes flush within the frame, creating a smooth and refined finish. This design adds character while still offering excellent performance.
Available in both uPVC and aluminium, our flush sash windows are versatile enough to suit different property types and they’re energy-efficient and low maintenance.
Colours and Finishes
Our flush sash windows come in a wide range of colours and finishes to complement your home. Choose from classic whites, sleek greys, or traditional woodgrain effects that replicate the charm of timber.
Whether you opt for uPVC or aluminium, Cliffside offers designs that can blend seamlessly with your existing property.

Traditional Style, Modern Benefits
Flush sash windows are designed to replicate the look of traditional timber windows, with the sashes sitting level within the frame for a sleek, understated finish. Available in both uPVC and aluminium, they combine timeless style with modern performance.
All of our flush sash windows are made-to-measure, offering excellent energy efficiency, low maintenance, and a wide choice of finishes to suit any home. Whether you’re after a clean, contemporary appearance or a traditional look with subtle detailing, these windows are a practical and stylish choice for many homes.
Perfect for Period Properties
Flush sash windows are especially popular for renovations and refurbishments in older homes, where authentic detailing is important. Many local planning authorities favour this style for use in conservation areas because of its similarity to original timber windows.
We can supply uPVC or aluminium flush sash windows that respect the character of your property while providing the comfort and efficiency of modern glazing. They’re an excellent way to retain your home’s heritage while improving thermal efficiency and reducing upkeep.

We asked Cliffside to replace our old conservatory including new foundation’s. We chose the solid roof option from Lela and had the interior plastered and the floor tiled, complete with under floor heating. All the staff a contractors were very professional and completed the works to a high standard. Communication with Cliffside was easy and any questions or issues we had were dealt with promptly.
We’re both absolutely delighted with our new room now being able to use it all year round. We would definitely recommend this company, thanks again Cliffside.
