Flush Sash Windows
Flush windows are characterised by window sashes that close into the frame, replicating the style of traditional timber windows.
Flush Finish for a Classic, Minimalist Aesthetic
Flush sash windows are a hybrid modern traditional double glazing window solution. They are distinguished by their classic lines that fit the flush perfectly into the window frame.
Heritage flush windows look great in any surrounding, whether they are being installed into a modern townhouse or country cottage. Blending seamlessly with the property aesthetic, they have slim sightlines and sit flush within the frames.
Our uPVC flush windows will retain their elegance while still functioning as a high quality flush window for many years to come providing a cost-effective and worthwhile investment for any home. You can find your nearest Deceuninck UK fabricator here or contact us today to find out more.
