Key Performance Features
⚡ Core Benefits- Low-E Coating: 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 manufactured to comply with global safety and performance standards, ensuring reliability across diverse markets.
🌍 International Standards
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.

Frequently Asked Questions
Q 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 separated by a sealed cavity filled with air or argon gas. A vacuum-sputtered low-e coating on the glass surface reflects infrared heat while allowing visible light to pass through, significantly improving a building's thermal performance and reducing energy consumption.
Q What international standards do South Star's Low-E IGUs comply with?
South Star's Low-E IGUs are manufactured to comply with major global standards including ASTM E2190 (USA), IGCC/IGMA Certification (USA/Canada), EN 1279 (Europe), and AS/NZS 4666 (Australia/New Zealand), ensuring reliability and performance across diverse markets worldwide.
Q Can Low-E IGUs be combined with laminated glass technology?
Yes. South Star offers IGUs with integrated laminated glass layers, providing enhanced safety (impact resistance and fragment retention), improved security against penetration, and greater design flexibility including acoustic interlayers, decorative printing, and BIPV integration.
Q What energy efficiency benefits do Low-E IGUs offer for buildings?
Low-E IGUs reduce heat gain during summer and heat loss during winter, significantly lowering HVAC demand. They also improve indoor comfort by stabilizing temperatures and reducing condensation on interior glass surfaces, resulting in long-term energy savings and reduced carbon footprint.
Q Are curved Low-E IGUs available, and can they maintain aesthetic consistency with flat units?
Yes. As demonstrated at The Henley in Hong Kong, Glaspedia supplies both flat and curved Low-E IGUs. The uniform low-e coating color across both unit types ensures consistent façade aesthetics and architectural harmony, even in complex building designs.
Q Can Low-E IGUs be integrated with BIPV (Building-Integrated Photovoltaics) systems?
Yes. As demonstrated at 470 Hennessy Road in Hong Kong, South Star successfully integrated BIPV IGUs alongside Low-E IGUs. This combination enables renewable energy generation directly within the building façade while maintaining high energy efficiency and full compliance with façade performance requirements.
