Flush Sash Windows
The perfect blend of traditional elegance and modern performance, ideal for heritage and contemporary homes alike.
Elegant Flush Sash Windows
Flush sash windows combine the timeless beauty of traditional timber windows with the durability and low maintenance of modern UPVC. The sash sits flush with the frame, creating a sleek, refined appearance that suits both period properties and contemporary homes.
Unlike standard casement windows where the sash protrudes from the frame, flush sash windows create a clean, flat finish that closely replicates the look of original timber windows — making them an excellent choice for conservation areas.
Every flush sash window we supply is manufactured to the highest standards, featuring advanced glazing, multi-point locking, and a choice of authentic finishes to complement your property perfectly.
