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

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 - 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 - 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 - 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 - 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 - 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
