Types of uPVC Windows 

New windows can have offer an extremely desirable effect on the appearance of your home, both from the inside and out. We offer a wide range of styles to suit both traditional and new build properties. Opt for traditional White windows, modern Anthracite Grey windows or natural Woodgrain effect windows, then decide if you would like Georgian Bar, Diamonds or Lead patterns to accompany the glass. Whatever style you go for, you'll find our windows aren't just pleasing on the eye, they're practical too. Minimal maintenance means their good looks will last well into the future. 

The UK's best windows

We only install REHAU uPVC windows because, in our professional opinion, based on many years of working with most (if not all) window profiles, they are the UK's best window. Each and every window offers high security multi-point-locking sashes with sac / shoot bolts fitted as standard, providing protection from forced entry attempts even when using 2nd stage locking to keep the air flowing. As well as being secure, they are also extremely thermally efficient and were the first window to ever achieve the A-Rated standard.   

Free Window Design Service

Installing new windows can offer you the chance to alter the overall appearance and character of your property. We are happy to offer advice on the style, colour and layout of your windows, whether you are trying to achieve a particular look or simply trying to stick to a budget. Or, you can design your own!

Casement Windows

The most popular window style installed within the UK, comprising fixed or outward opening, side or top hung sashes.

These can also be coupled to produce Bay and Bow Windows. The majority of windows in UK homes are Casement Windows, or Bay / Bow Windows made up of Casement Windows.  Don't worry if you're not sure what you need, we're always happy to offer advice, both charge and obligation free. 

Bay Windows and Bow Windows

Many people do not know the difference between Bay Windows and Bow Windows, but we can help explain it to you now!

A Bay Window usually extends outwards from the property in a rectangular shape. A Bow Window forms an arch and often requires a canopy above.

Tilt & Turn Windows

A popular alternative style to the casement window is the Tilt and Turn window. This features a dual opening mechanism for security, safety and practicality.

By twisting the handle 90 degrees the sash tilts inwards to provide gentle ventilation; when turned to 180 degrees the side hinges engage to enable the window to be fully opened into the property for ease of cleaning. This is often used as a fire escape. 

Vertical Sliding or Box Sash Windows

Vertical Sliding Windows, also known as Box Sash Windows combine the elegance of traditional sash windows with the enhanced performance benefits and structural integrity of modern materials requiring minimal maintenance.


Whether replacing existing timber sliding sash in period buildings or adding character to any new development, they come complete with an easy clean facility for practicality as well as performance and aesthetics.
