What are flush sash windows?
Intricately made to seamlessly replicate the look of authentic timber, flush sash windows fit sleekly into the window frame, instead of slightly overlapping the window frame for a smooth finish. Made from the highest quality uPVC, unrivalled energy performance, weatherproofing, and low maintenance finesse are a given. Well-known for the way they create traditional aesthetics without the traditional drawbacks, even the keenest eye won’t be able to tell the difference!
