Britannia Double Glazing windows are made bespoke for you in a wide range of options and colours.

UPVC Sash Windows

Our sash windows feature two sashes which slide past each other and also tilt inwards for ventilation. Although Sash UPVC windows are usually associated with historic properties, they also look great on modern homes – by adding a touch of class as well as a traditional look.

UPVC Casement Windows

Casement UPVC windows are those where the window opens outwards either a top, bottom or side opening sash. All our casement UPVC windows have a multipoint security locking feature & can be fitted with a restricting hinge for the safety of children. We also fit a special hinge to your best-suited window to be used as a fire escape.

UPVC Tilt & Turn Windows

Our tilt & turn UPVC window is a traditional style of window equipped with a sash which opens in two ways. Either, the whole of the sash opens inwards, allowing you to clean the outside pane safely from the comfort of your home. Or you can tilt the UPVC window inwards from the top to allow for safe yet effective ventilation.

A++ Rated UPVC Windows

Our state of the art, Triple glazed UPVC Windows offer the best heat retention and energy efficiency of any of our frames. By maximising the sunlight radiated, the extra glass panel will ensure no heat is lost, making your home warmer and reducing the cost of your heating bills. Another great feature of these A++ rated UPVC windows is that it will reduce the noise coming in from outside.


Our collection of double glazed UPVC windows and doors are available in a wide range of woodgrain and colours to ensure that they enhance and complement the style of your home.
