What is a flush sash window?

A flush sash window is designed to give a completely flush appearance, which gives your homes exterior a stylish look. Flush sash windows have become a popular choice for period properties, as their flush finish and woodgrain effects adds charm.

Flush sash windows are very versatile. This allows you to fully customise your windows to compliment your home whether you have an old property or a new build. At the Nottingham Window Company, we offer an extensive range of anti-fade finishes, bespoke accessories and a variety of RAL colour options.
