Glazing Options
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. Watch the video on our the Rationel website.
Rationel OBSCURE
Rationel 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
This glass holds together when shattered, reducing the risk of injury if someone falls into the pane. The toughened glass is designed to fall out of the sash and shatter into small, harmless pieces. 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
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
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.
Secured by Design and Part Q
Rationel Windows and Doors
Our experience working with housing associations, community developments and commercial projects means the security and safety of Rationel doors are second to none.
Additionally, Rationel windows and doors are tested and marked according to several national and European standards, as well as Secured by Design. Therefore, the frame, lock and hardware can withstand common burglary methods.
To meet Part Q requirements, Rationel windows and doors must satisfy particular standards of robustness, use approved hardware and demonstrate proven security performance.

Reinforced screws
Extra-strong reinforced screws increase the strength of all hinges.
Hook bolts
Hook bolts in hardened steel combined with a reinforced front plate resist even severe attacks.
