Opening Types


Top Guided

Top Guided

Top Guided windows are a simple, elegant and user-friendly design. Opening is controlled by tracks and slides. When opening the window the top of the sash slides downwards as the bottom of the sash opens outwards. Adjustable friction ironmongery allows an almost infinite choice of open positions.

Top Swing

Top Swing

In everyday operation the fully reversible window functions as a Top Guided window. However it is possible to turn the sash through 170 degrees to clean the glass from the inside.

Fixed Light

Fixed Light

Fixed Light windows are ideal wherever maximum internal light and solar heat gain is required. Fixed Lights can be fitted with trickle vents for ventilation.

 

Side Guided

Side Guided

Side Guided windows are controlled by tracks and slides that allow the window to be fixed in any open position. However, when opened, the hinge side of the sash moves toward the middle to create an opening that allows the glass to be cleaned from the inside.

 

Side Hung

Side Hung

Side Hung windows are controlled with tracks and slides. On windows over 424 mm wide and 530mm high, the handle controlled friction brake allows the window to be fixed in any open position.

Glazing Options

Rationel windows combine safety, privacy and energy-efficiency features that help you make the very best of your home.

Rationel Secure

Rationel SECURE - Our windows are built with security in mind. Read more about our Secured by Design certification or watch the video on our website

Rationel Obscure

Rationel OBSCURE - Our panes are designed to restrict the view into private areas such as bathrooms. Choose from six different types of glass to get the combination of light and privacy you desire

Rationel Safety

Rationel SAFETY - Our glass holds together when shattered, reducing the risk of injury if someone falls into the pane. Panes can be made of toughened glass, laminated glass or a combination of both

Rationel Facade

Rationel FACADE - Used in buildings either to create a visually coherent facade or for special colour effects, FACADE is well suited to storey divisions as well as ventilated and insulated panels, and is available in special colours on request

Rationel Sound

Rationel SOUND - Our windows are built with security in mind. If your home is subject to environmental noise, our noise reducing panes are for you. Panes feature two glass sheets that act as a break, dramatically reducing the movement of sound into your home and creating a peaceful environment

Rationel Solar

Rationel SOLAR - Our solar panes limit the amount of sunlight and heat coming into a building, depending on the light and heat shielding levels required. This means significantly less energy will be required to cool hot rooms
