Simple Lifting Window is a minimalist vertical lifting window system. It is ideal for affordable housing renovations, classrooms, and chain hotel projects where frequent operation and low maintenance are critical.
features
Easy Operation
Modular gravity balance system and trackless design allow one-hand lifting even by elderly users.
Tool-Free Installation
Quick-install buckles enable installation in minutes without professional labour or specialised tools.
Safety Protection
Air pressure buffer slows closing to reduce the risk of pinching users' hands.
Sound Insulation
– Single-Layer Glass: Reduces noise by ~32 dB, ideal for interior partitions.
– Upgraded Insulating Glass: Achieves ~42 dB sound reduction, suitable for street-facing rooms.
Minimal Maintenance
Graphene-coated bearings reduce friction and eliminate regular oiling.
Long-Lasting Durability
– Cycle-Tested: Withstands 100,000 opening/closing operations, reliable for high-frequency use.
– Reinforced Frame: Embedded galvanized steel (≥1.5 mm wall thickness) provides 60 kg load capacity per single window.
Weather Resistance
– Sealing Strips: Endures -30 ℃ to 80 ℃ thermal cycles 200 times without cracking or fission.
– Pulleys: Glass fiber reinforced nylon with water absorption <0.1% ensures smooth operation in humid environments.
– Balance Chamber: IP6X enclosure; 90% reduction in dust accumulation and jamming compared with traditional slotted tracks.
– Sealant: Anti-aging formula maintains long-term sealing performance under sunlight exposure.
