Fully reversible window
This multi-functional window style is highly suitable for multi-storey buildings. Outward opening and similar to our top guided window, the sash in this case can be rotated up to 180 degrees on a horizontal axis. Not only does this make it incredibly easy to clean, but also allows for optimum ventilation in your home.
Top guided window
The opening function of a Rationel top-guided window is controlled by tracks and slides. Suitable for all rooms and with no visible external hinges, every single one of our top guided windows is made totally bespoke for you, with the promise of exceptional durability.
Side hung window
Our side hung windows make for an ideal emergency or ‘rescue’ exit. Their height and width fall within the recommended measurements set by current building regulations for this feature – so you and your family can have peace of mind, for now and for tomorrow.
Side guided windows
Our side guided windows come complete with a sleek and practical design, with no visible external hinges and an adjustable sash which moves towards the middle when opened.
Tilt and turn window
Tilt and turn windows are unique in that they function in two ways. The tilt function opens the top of the sash, allowing fresh air to ventilate the room. The turning function allows for them to be opened inwardly, hinging from the side.

Fixed Light
The glass of our fixed light window is inserted directly into the frame, meaning their function is not to open, but to let more natural light and warmth into your room. With a larger area of glazing and slimmer window frame, this makes them perfect for those countryside lodgings.

Bespoke window shapes and designs
Our range of shaped windows can be designed to suit any room of your home, adding elegance and style to bathrooms, bedrooms, entranceways and much more.


Aluminium Windows from Sunflex
For more than 20 years, SUNFLEX UK has been providing contemporary, high quality aluminium windows. The extensive range of aluminium windows includes made-to-measure options for almost any type of project, from new build to renovation, or replacements for existing units.

SAL300 Slim
Glazing: Double glazed
Uses: Casement (including top hung or side hung) and fixed frames
The highly engineered window system provides a modern, slender framed window with stylish square edge profile. Designed from frames with 53mm depths, the SAL300 Slim can be manufactured to the exact requirements of your home, including side and/or top hung sashes if openings are required.
The slender frames also make the system perfect for large fixed frame picture windows where the goal is to maximise the amount of glass to make the most of the view out into the garden and beyond.
SEF
Glazing: Double or triple glazed
Uses: Casement (including top hung or side hung), tilt & turn, fixed frames, frameless glass-to-glass corners and inline joints, gable end glazing and angled frames.
Available double or triple glazed for the ultimate in thermal efficiency, the SEF window is hugely versatile with a wide range of opening options and capable of achieving larger sash sizes.
The versatility of the system makes it ideal for multiple window styles on the same property or elevation and it is also ideally suited for integration alongside our sliding or bifold doors to create a complete glazing solution.

Colour Options
We have chosen a selection of the most popular colours for each system to hold in stock. In addition to our standard colours, you can personalise your windows with a choice of more than 200 RAL finishes, and even opt for different colours on the interior and exterior frames of the doors to perfectly match your home.
