Opening Functions
Our windows and doors are available in a range of variable opening functions. Listed below are all of the opening styles that Rationel offer. Certain products only offer certain opening functions, please enquire to confirm which functions are offered for the product you are interested in.
Windows
Fixed light windows
Fixed windows are perfect for maximising the amount of light inside your home and bringing out the beauty in the scenery around you. The glass of a fixed 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, fixed windows are ideal for properties based in the countryside.
Advantages of fixed windows
1. Highly energy efficient
2. Maximum use of light
3. Optimal views of your surroundings

As a result of these functions, tilt and turn windows can easily be cleaned from the inside, and are perfectly suited as “escape windows” or emergency exits.
