UPVC Windows

B&G windows offer double glazed window installations in Hertfordshire and throughout London.


All of our windows are made to order and can be supplied in a variety of styles including casement, tilt and turn and vertical sliders.

Casement Windows
Low maintenance, Long lasting

Casement windows are single or double-panelled windows, hinged from the side, top or bottom. Operated with a handle, panels open outward and close proud of their frame. They are our most popular window for their ease of use and availability in different styles.


If you’re looking for a modern, no-fuss window, then uPVC casement windows are the right choice.


Our uPVC casement window frames have trickle vents for ventilation and can be placed on the latch to reduce unwanted condensation. Looking for something different to a standard white gloss finish? Your chosen frames can be foil-coated with the colour of your choice and customised with handle and glass options.

Tilt & Turn Windows
Streamlined style & practicality

Tilt and turns combine simple, streamlined style with real practicality.


These windows are hinged at the base and tilt inwards for ventilation. With an extra turn of the handle, the frames can open fully into the room on a side hinge.


That full opening means that tilt and turns can easily be cleaned from indoors so there is no need to struggle with ladders or to employ a window cleaner.

Vertical Sliding Windows
Traditional style, elegance & charm

A traditional sliding sash window with elegance and charm. Our vertical sliders are renowned in the industry for their faithful replication of timber sash styling and for their advanced features. They include sashes that tilt inwards for ease of cleaning, child-safety catches, secure locking mechanisms and effective weatherseals.


Even better, and great news when you’re replacing timber sashes, these widows are designed to achieve a Window Energy Rating of ‘A+’. If you’re trying to match existing glazing, you’ll love the options available with our vertical slider.


These include Georgian bars, sash horns and deep bottom rails as well as a wide choice of colours, cills and hardware.
