Profile Systems

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.

Frequently Asked Questions

Single & Double Hung Window Technical FAQ

Key technical insights for procurement managers, structural consultants, and project developers.

What is the difference between a single hung and a double hung aluminium window?
In a single hung window, only the bottom sash moves vertically while the top sash remains stationary. In a double hung window, both upper and lower sashes operate vertically and tilt inward, allowing flexible airflow control and easy cleaning from inside the building.
Does KARON manufacture thermal break hung windows for cold or hot climates?
Yes. Karon Window & Door Co., Ltd. produces thermal break hung windows featuring high-density PA66 polyamide insulating strips. Paired with double or triple Low-E argon-filled glass, our systems meet strict energy efficiency standards in North America, Australia, and Europe.
What hardware and balance mechanisms are used in KARON hung windows?
We utilize heavy-duty constant force spring balances and spiral balance hardware systems sized precisely to sash weight. This ensures smooth fingertip operation, reliable hold at any height position, and extended service life under frequent commercial use.
Are KARON single and double hung windows certified for overseas building standards?
Yes, our glass units and window assemblies comply with international safety and performance standards including US SGCC, Australia AS 2208, Europe CE EN 12150, Thailand TISI, and Malaysia CIDB qualifications.
