Casement Windows
Casement Windows are the most popular choice of window style and are available in a wide range of opening options, frame colours, finishes, glass, locks and handles.

Casement Windows
PVCu casement windows which give you more choice including 17 foil colour options from stock.

TIlt and Turn
The Tilt and Turn Window is a great choice for low and high level installations. They have two opening options; the first is an inward top tilt which allows fresh air to circulate. Whilst the turn function allows the window to open fully inwards, making it great for easy access cleaning and also ideal as a fire escape.

Tilt and Turn
Tilt and turn windows offer maximum airflow with the benefit of easy access for maintenance and cleaning.

Flush Sash Window
Flush Sash Windows offer a style of casement frame where the window opening (sash) sits flush to the frame. These windows can be foiled to look like timber frames in a choice of wood grains and colours but without the costly and time consuming maintenance of real wood. Alternatively they can be finished with a sleek and contemporary look.

Sliding Sash Window
Sliding Sash uPVC Windows give a traditional appearance while providing all the benefits of modern uPVC window engineering.
Low maintenance and noise reduction are just two of the benefits of these period style windows systems. We can advise on aesthetic features and hardware options so you can get the best windows to suit your home, style and budget.

Bay Windows
Bay and Bow Windows offer light and alcove space while creating an interesting focal point in the home. The range of styles and colours available can be added to with Georgian or astral bars, sash horns, leaded glass and of course a choice of frame colour options. The less common triangular bay windows can also be accommodated.

Bay Window
Bay Windows offer an elegant looking exterior to your property and a sense of space and light inside. We can advise on the best glass units to fit as well as hardware to compliment your bay windows, your property and your budget.

Sash Horn Window
Originating from Victorian design, the Sash Horn Window has been modernised to maintain the classic look of the wooden box-sash while offering weather tight, secure, C21st functionality with casement window opening and the option to add Georgian bars.

Pivot Windows
As the name suggests the Pivot Window rests on two axis points allowing 180° rotation. Ideal for use in multi-storey, flats and hard to reach access areas. Natural light can flood in through the large glass area while the rotation makes cleaning a doddle.

Bi Fold Windows
Bi Fold Windows open out in a concertina movement to create an open space bringing the outside in or vice versa. The smooth sliding mechanism allows you to effortlessly and easily transform your home in the summer months. Bi Folds are also ideal for use in commercial settings such as restaurants, and cafés. With high energy efficiency and security as standard, these windows can add a modern contemporary feel to any property.

Security is paramount and all the products we supply are certified and tested: Secured by Design* BBA Approved* and BS* tested. We believe our customers deserve quality and peace of mind guaranteed, as standard.
The choice of frames can be a little overwhelming with many traditional and contemporary styles to choose from. Our knowledgeable colleagues will guide you through the process and help you consider all the options suited to you, your home or office and your budget.
Installing energy efficient windows and doors is a great way to save energy costs in your home, allowing you to enjoy the benefits of natural light while keeping the heat in and the chill winds out. Our most popular range of window glass is the Planitherm Glass Range which can help maximise comfort in your home.
Our Bristol Branch is proud to be a BFRC rainbow rating certified company.
“BFRC is the UK’s most trusted ratings council, with the most widely used rating system for energy performance in window and doors.”
