uPVC windows can suit many different homes. From traditional to modern, your windows will come in a range of colours, shapes and styles to suit your property. uPVC is a strong and resilient material that will stand the test of time and provide excellent performance, making it the most commonly used material for window frames in the UK.
What is uPVC?


A casement window is a hinged window that opens outwards and is fitted into a frame. There may be one window per frame, or there may be multiple windows sat within the same frame, meaning there are various options for window configuration. A casement window opens outwards using a friction stay hinge and fits snugly into the frame to keep out draughts.

Our windows exceed British Standard regulations, using galvanised steel for additional strength and security.


A sash window is a movable panel, or multiple movable panels, that are hung within a frame. These movable parts are called the sash, and they also contain the glazing for the window. The very first sash windows can be dated back to the 1670s and in terms of their appearance, they are fundamentally the same. Technology, however, has changed significantly, and if you still have the original sash windows in your property, you will benefit enormously from getting some new ones installed.

uPVC sash windows can be manufactured to have many different finishes. Choose a RAL colour or opt for a traditional woodgrain effect.
