Flush Sash Windows

Creating or maintaining a traditional aesthetic for your home doesn’t need to come at the cost of the environment or energy efficiency.

Flush sash windows are low maintenance, thermally efficient and attractive, using modern materials to create a traditional look.

A simple yet beautiful design, these windows are a great addition to any home. The traditional look does not mean compromise on technical prowess, the flush sash offers outstanding thermal efficiency and security.

Our windows have an outstanding weatherproofing system to keep out leaks and drafts so you can enjoy a comfortable home in style.

Our flush sash windows come in a variety of colours to suit your home and to make them even more appealing they are 100% recyclable.
