Are RATIONEL casement doors right for your property?
Rationel casement doors are a good fit for patio access, balconies, side entrances and garden-facing rooms where a traditional hinged opening is preferred. They work particularly well when the surrounding windows are also Rationel, creating a consistent look across the whole elevation. Choose them where everyday access, natural light and premium timber detailing are more important than a large sliding opening.
