UPVC Casement Windows

Based in Droitwich Spa and covering all areas of the West Midlands, Diamond Windows Droitwich are leading uPVC window manufacturers in the UK.

Our uPVC casement window styles are a popular choice for homeowners because of their classic, chic appearance and ‘A’ energy rating, ensuring your home retains heat, saves you money, and looks good doing it. 

Wide Range of Finishes and Styles for UPVC Casement Windows

We offer many different types of casement windows made to almost any specified height and width. We also provide eight standard colours, including white, cream, black/brown, dark green, Chartwell Green, Anthracite Grey, Painswick Grey and slate grey. If you prefer the look of wood casement windows but like the durability, efficiency and overall finish of uPVC, we are able to supply an Irish oak, golden oak, white ash, or rosewood wood grain finish.

You can even choose your desired glazing finish, including diamond or square lead work, and astragal or internal Georgian bars.

10 Year Guarantee

All of our double-glazed casement windows are easy to maintain and keep looking like new, partly due to their durability and longevity. We’re so confident in our windows that we offer a ten-year guarantee as standard.

Enhanced Glazing Options for UPVC Casement Windows

The high-tech glass technology we use for our range of casement windows allows us to take advantage of improved energy efficiency, enhancing your home’s insulation and allowing you to minimise energy bills and noise pollution. The invisible PLANITHERM coating captures daylight energy and reflects it inwards to warm your home, all whilst reducing the risk of condensation and without creating a noticeable tint or haze.

Diamond Windows Droitwich also installs enhanced glazing and triple glazed uPVC windows which reduce noise pollution. The extra pane of glass not only helps with increased thermal efficiency but it can also make your home more secure.
