  • Design Flexibility: Options for acoustic interlayers, decorative printing, or BIPV integration expand architectural possibilities.
🌟 South Star LowE Insulated Glass Units represent the convergence of energy efficiency, safety, and sustainability. With proven performance in landmark projects such as 470 Hennessy Road and The Henley, and the ability to combine lamination with IGUs, South Star continues to deliver glazing solutions that meet the evolving demands of modern architecture and urban development.
Frequently Asked Questions
What is a Low-E IGU and how does it work?
A Low-E (Low Emissivity) Insulated Glass Unit (IGU) consists of two or more glass panes with a vacuum-sputtered low-e coating applied to the glass surface. This coating reduces infrared heat transfer while allowing visible light to pass through. The sealed cavity between the panes, often filled with air or argon gas, further minimizes heat conduction and improves overall thermal performance.
What international standards do Low-E IGUs comply with?
Low-E IGUs can be manufactured to comply with multiple global standards including 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, thermal insulation, and long-term performance reliability.
How do Low-E IGUs contribute to energy savings?
Low-E IGUs reduce heat gain in summer and heat loss in winter, which directly lowers the demand on HVAC systems. This results in significant long-term energy savings for buildings, contributing to improved energy efficiency ratings and reduced operational costs.
Can Low-E IGUs be combined with laminated glass technology?
Yes. Low-E IGUs can be enhanced by integrating laminated glass technology, which provides added safety through impact resistance and fragment retention, improved security against penetration, and greater design flexibility including options for acoustic interlayers, decorative printing, or BIPV integration.
Are Low-E IGUs suitable for curved architectural applications?
Yes. As demonstrated in The Henley project in Hong Kong, both flat and curved Low-E IGUs can be produced with uniform coating color to ensure optimal façade aesthetics and architectural consistency. This makes them suitable for complex architectural designs in modern urban developments.
What makes Glaspedia a reliable supplier of Low-E IGUs?
Glaspedia (South Star) has demonstrated proven performance in landmark projects such as 470 Hennessy Road and The Henley in Hong Kong, delivering both Low-E IGUs and BIPV IGUs that meet stringent façade performance requirements. Their products adhere to international benchmarks for safety, durability, and sustainability, making them suitable for both local and global projects.
