China Low-e Insulated Glass Units - High Performance IGUs from Top Suppliers and Factory
,
Glaspedia Low Emissivity (Low e) Insulated Glass Units (IGUs) are expertly crafted to enhance thermal efficiency while ensuring clarity and comfort. Manufactured in China, our IGUs feature multiple glass panes separated by a spacer, creating a sealed cavity filled with insulating air or inert gas. As leading suppliers in the industry, our factory utilizes advanced technology and materials to produce high-quality insulated glass solutions that meet various architectural needs. Choose Glaspedia for superior thermal performance and transparency in your projects.
Vacuum sputtered low-e coatings applied to the glass surface reduce infrared heat transfer while allowing visible light to pass through.
🌡️ Thermal Insulation
The sealed cavity, often filled with air or argon gas, minimizes heat conduction and improves U-value performance.
⚡ Energy Savings
Reduced heat gain in summer and heat loss in winter lowers HVAC demand, contributing to long-term energy efficiency.
💧 Comfort & Condensation Control
Improved indoor temperature stability and reduced condensation on interior surfaces.
Low-e IGU is to be manufactured to comply with global safety and performance standards, ensuring reliability across diverse markets:
ASTM E2190 (USA)
Defines IGU durability and performance, testing seal integrity, moisture resistance, gas retention, and fogging prevention.
IGCC/IGMA Certification (USA/Canada)
Certification program ensuring IGUs meet ASTM E2190 requirements through audits, sample testing, and long-term performance verification.
EN 1279 (Europe)
Governs IGU performance, covering moisture penetration, gas leakage, mechanical strength, optical quality, and thermal insulation durability.
AS/NZS 4666 (Australia/New Zealand)
Establishes IGU requirements for durability, moisture resistance, gas retention, and long-term thermal performance in buildings.
By adhering to these standards, South Star ensures its laminated glass solutions meet international benchmarks for safety, durability, and sustainability, making them suitable for both local and global projects.

Frequently Asked Questions
What is a Low-E IGU and how does it work?
A Low-E IGU (Low-Emissivity Insulated Glass Unit) consists of two or more glass panes with a vacuum-sputtered low-emissivity coating that reflects infrared heat while allowing visible light to pass through. The sealed cavity between panes — often filled with argon gas — further reduces heat conduction, improving overall thermal performance.
What international standards do Low-E IGUs need to comply with?
Low-E IGUs are manufactured to comply with ASTM E2190 (USA), IGCC/IGMA Certification (USA/Canada), EN 1279 (Europe), and AS/NZS 4666 (Australia/New Zealand). These standards cover durability, moisture resistance, gas retention, optical quality, and long-term thermal performance.
How do Low-E IGUs contribute to energy savings in buildings?
By reducing heat gain in summer and heat loss in winter, Low-E IGUs significantly lower HVAC demand. This leads to reduced energy consumption, lower utility bills, and a smaller carbon footprint — making them an essential component in sustainable and energy-efficient building design.
Can Low-E IGUs be combined with laminated glass or BIPV technology?
Yes. South Star offers IGUs that integrate laminated glass technology for enhanced safety, security, and design flexibility. Additionally, BIPV (Building-Integrated Photovoltaics) IGUs can be incorporated, as demonstrated at 470 Hennessy Road in Hong Kong, enabling renewable energy generation within the façade itself.
Are curved Low-E IGUs available for complex architectural projects?
Yes. As demonstrated at The Henley in Hong Kong, Glaspedia supplies both flat and curved Low-E IGUs. The uniform coating color across both unit types ensures consistent façade aesthetics, making them suitable for architecturally demanding residential and commercial projects.
What are the key benefits of using Low-E IGUs in high-rise residential buildings?
Low-E IGUs in high-rise residential applications deliver superior thermal comfort, reduced indoor condensation, improved energy efficiency, and enhanced occupant well-being. They also contribute to green building certifications by meeting stringent energy performance standards required in urban developments.
