HIRT Kinetics® HF-90

Lift Your Vision. Redefine What Windows Can Do.

HIRT kinetics HF 90 redefines the boundaries of modern architecture by introducing an upward-opening solution at a scale once thought impossible. This innovative system brings the elegance of vertical motion to large-scale window surfaces, offering a striking alternative to traditional opening methods.
