Living room with panoramic windows made from sliding elements looking out onto a lake

Corner opening

Sliding window elements from swissFineLine make it possible to install openable windows around corners. This unifies interior and outdoor spaces in a unique manner and creates a sense of boundless freedom.

Frameless sliding windows from swissFineLine enable you to open and close even large-format glass façades as you wish. Open corners are a true architectural highlight and seem to break down a room’s spatial limits. Balconies, terraces and gardens essentially become a natural extension of indoor space. Plus, thanks to the step-free floor rails, the transitions between interior and outdoor spaces fade away completely with the corner windows open.

swissFineLine offers clients and architects almost infinite freedom in their designs, paving the way for pioneering glass architecture. All sliding window systems are designed and tailor-made in accordance with your specific wishes. Corner openings can be realised as both internal and external corners. It is a particularly impressive option when installed without any pillars or posts disrupting the glazing. This creates unique, panoramic views.

What is a corner opening?

A fully glazed corner, also known as an open corner, is when the corner of a building is fully glazed and both window elements can be moved and opened.
