Custom Aluminium Single & Double Hung Windows
Engineered by Karon Window & Door Co., Ltd. for residential developments, villas, hotels, and commercial projects demanding classic vertical sightlines and space efficiency.
With over 15 years of manufacturing expertise in Foshan, China, our 10,000 m² standardized plant crafts precision vertical sliding window systems tailored to exact project drawings. Featuring heavy-duty constant force spring balances, tilt-in sashes for effortless exterior cleaning, and multi-chamber thermal break aluminium extrusions, KARON hung windows provide smooth operation and long-term durability.
- Space-Saving Operation: Vertical movement keeps sashes within the frame profile, freeing interior and exterior patio space.
- Dual-Sash Ventilation: Double hung options allow both top and bottom sashes to open simultaneously, driving natural air convection.
- Global Compliance: Tested to SGCC, AS 2208, CE EN 12150, TISI, and CIDB international safety standards.
Thermal Break & Standard Hung Window Options
Configure profile insulation, frame thickness, glass build-ups, and hardware to meet specific building codes and climatic conditions.
Thermal Break Hung Window
Features high-density PA66 polyamide thermal barrier strips separating inner and outer aluminium frames. Significantly reduces U-values and interior condensation, making it ideal for energy-code compliance in North America and Europe.
Non-Thermal Break Hung Window
Constructed from high-tensile 6063-T5 aluminium alloys. Delivers robust structural integrity and cost efficiency for tropical climates, interior partitions, and budget-conscious residential developments.
Tilt-In Sash Double Hung System
Both sashes slide smoothly vertically and tilt inward at 90 degrees. Enables safe, easy cleaning of glass exterior surfaces from inside high-rise apartments or luxury villas.

Why Overseas Contractors & Architects Choose KARON
Every hung window unit undergoes rigorous quality control at our Foshan facility prior to ocean shipment.
Multi-chamber thermal break profiles combined with argon gas-filled Low-E insulated glass dramatically cut HVAC heat gain/loss while dampening outdoor noise pollution up to 35 dB.
Engineered spiral balance systems are custom-calibrated to exact glass weights, guaranteeing smooth one-finger lifting, effortless positioning, and long-term durability without sagging.
Integrated zinc-alloy sweep locks, anti-lift security blocks, and continuous EPDM seals guard against forced entry, heavy rain intrusion, and high wind-load pressures.
Match facade architectural themes precisely with custom RAL powder-coat shades, architectural anodizing, or realistic wood-grain textures that resist UV degradation and ocean spray corrosion.
