Inward-Tilting Upper Drafts Eliminating Direct Draft Discomfort
Sashes tilt inward from the top, deflecting incoming fresh air towards ceilings for gentle draft-free natural ventilation.
Engineered for low-energy buildings, our bottom-hung hopper windows feature inward-tilting mechanics, deep thermal breaks, and safety limiters for draft-free ventilation and high insulation.

Wide polyamide struts stop cold bridging, preventing interior frame sweating and mold during severe sub-zero winters.
High-strength limit stays resist 1,000N pull forces, eliminating sash detachment and fulfilling institutional anti-fall mandates.
Beads mount from room interiors, allowing broken pane replacement without costly exterior scaffolding or building downtime.
