Introduction

High-Efficiency Glazing Solutions

Our Low-E (low-emissivity) glass series features microscopically thin layers of silver and metal oxides to reflect long-wave infrared energy. Available in single, double, and triple silver configurations, these units are designed to optimize thermal comfort while maintaining high levels of natural daylight for modern curtain wall systems.

Benefits

Why Choose APEX Low-E Glass Systems

  • Superior Thermal Insulation Performance

    Reduces heat transfer between the interior and exterior, significantly lowering HVAC energy consumption in both summer and winter.

  • Advanced Solar Heat Control

    Triple silver coatings provide an exceptionally low SHGC, blocking solar heat gain without compromising the transparency of the facade.

  • UV Radiation Protection

    Filters out a high percentage of ultraviolet rays, protecting interior furnishings and finishes from fading due to sun exposure.

  • Enhanced Neutral Aesthetics

    Engineered for low reflectivity and high color rendering index (CRI), ensuring a neutral appearance and clear views from the interior.

Standard

Custom Configurations & Processing

Our Low-E glass can be customized in various Insulated Glass Unit (IGU) configurations, including argon gas filling, warm-edge spacers, and laminated safety glass layers to meet specific acoustic and structural requirements.

Processing options include full tempering, heat-strengthening, and silk-screen printing. We utilize world-class vacuum sputtering lines to ensure coating uniformity and long-term durability across large-scale architectural batches.

FAQS

Frequently Asked Questions

Technical insights into selecting the right Low-E coating for your specific climate and building design.

What is the difference between Single, Double, and Triple Silver Low-E?
The number of silver layers determines the selectivity; Triple Silver offers the best ratio of high light transmission to low solar heat gain.
Can Low-E glass be used in monolithic form?
No, the soft-coat Low-E layer must be sealed inside an Insulated Glass Unit (IGU) to protect it from oxidation and mechanical damage.
Does Low-E glass affect the color of the building?
Modern coatings are designed for neutrality, but different silver levels can introduce subtle blue, green, or grey tints depending on the specification.
How does argon gas improve the performance of Low-E units?
Argon is denser than air, reducing convective heat transfer within the IGU and further lowering the overall U-value of the system.
Is your glass compliant with international standards?
Yes, our glass products meet ASTM C1036, EN 1279, and AS/NZS 2208 standards for safety and performance.
