Single Hung vs. Double Hung Architectural Configurations
Vancoor Entrance System Co., Ltd. provides both single hung and double hung structural configurations depending on project ventilation dynamics and maintenance goals.
Single Hung Aluminum Windows
Configuration: Features a fixed top glass sash and an operable bottom sash that glides vertically.
Key Advantages: Superior air tightness at the top fixed joint, higher overall structural rigidity for large window openings, and lower initial unit cost. Ideal for multi-family residential housing, hotels, and office developments standardizing fixed upper transoms.
Double Hung Aluminum Windows
Configuration: Both top and bottom sashes operate independently in vertical tracks and feature tilt-in release levers.
Key Advantages: Superior natural convection ventilation (cool air enters via bottom sash while warm air exits top sash). Both sashes tilt inward for safe indoor glass maintenance, making them ideal for multi-story residential homes and luxury villas.

Frequently Asked Questions for Overseas Buyers
What is the key functional difference between Single Hung and Double Hung windows?
In a single hung window, only the bottom sash slides vertically while the top sash stays fixed. In a double hung window, both the top and bottom sashes open vertically and feature tilt-in mechanisms for easy glass cleaning from inside the room.
How does Vancoor ensure thermal efficiency and weather tightness on hung windows?
Vancoor Entrance System Co., Ltd. incorporates high-density PA66 nylon thermal break strips inside primary 6063-T5 aluminum extrusions, coupled with Low-E argon insulated glass units and continuous multi-barrier EPDM rubber seals along all sash interlocks.
Can Vancoor produce hung windows tailored to specific building codes?
Yes. We design and manufacture custom hung windows compliant with target market codes including North American NFRC/AAMA ratings, Australian AS2047, and European CE benchmarks. Complete CAD shop drawings and test certificates are provided per order.
What custom options are available for wholesale & project orders?
