Seamlessly merging indoors with the outdoors, the HIRT Kinetics SF 90 glides open in a silent, fluid motion—vanishing entirely into the floor to unveil architecture in its purest form.

This sense of effortless weightlessness isn’t just visual; it’s made possible by a precisely counterbalanced mechanism. With an ultra-slim sash depth of just 90 mm, the SF 90 delivers sleek sophistication and can be engineered in impressive dimensions up to 6 meters.
