Azuma Design offers specialised testing services for Insulated Glass Units (IGUs), ensuring compliance with stringent Australian standards for energy efficiency, durability, and thermal performance.

Our tests help guarantee that your building components meet the highest standards for structural integrity and weatherproofing.

Insulated Glass Units (IGU) Testing (AS4666, EN1279):

We ensure that IGUs are tested for Moisture Penetration standards, focusing on thermal performance and long-term product reliability.

Our Products and Services

At Azuma, we provide cutting-edge testing solutions for the construction industry, helping builders, designers, and developers ensure their projects meet both national and international standards. Our NATA-accredited facilities specialise in structural, safety, and weatherproofing tests that comply with NCC, AS, and EN standards. With a focus on testing building components, IGUs, and balustrades, we ensure your projects are safe, durable, and compliant.

Insulated Glass Units (IGUs): Are They Fit for Purpose?

IGUs are vital components of double-glazed windows, providing essential insulation to maintain comfortable indoor environments and reducing energy usage. At Azuma, we rigorously test IGUs to ensure are adequately sealed for moisture penetration with the requirements set out in AS4666 and EN1279.

Why IGUs Matter:

IGUs are crucial for energy compliance as Australia moves towards more efficient electricity use. Unlike single glazing, IGUs improve insulation, making buildings more energy-efficient and reducing heating and cooling costs.

How We Test:

We place IGUs in an accelerated weathering cabinet for 77 days, cycling between -18°C and 53°C with 95% humidity for 1 month and 58 deg 95% Humidity for 2 months.. This simulates extreme conditions to ensure the units can withstand environmental stresses without compromising their integrity. We measure moisture content before and after testing—significant moisture increase indicates a failure, requiring corrective actions in the manufacturing process.

Seal Integrity and Gas Retention:

For long-term durability, IGUs must have correctly applied primary and secondary seals to prevent moisture penetration between glass panes. Seal failure can lead to moisture ingress or gas leakage (e.g., argon), reducing insulation performance and causing visual issues like fogging.

Sparklike Testing:

Our Sparklike Testing measures gas concentration levels in double-glazed IGUs, ensuring the argon fill remains intact and enhances insulation by 10-15%. Proper seal integrity is crucial for maintaining this advantage.

Manufacturer Requirements:

Manufacturers are required to type test their IGUs every two years. At Azuma, we ensure IGUs meet the long-term requirements of AS4666, guaranteeing high-quality products that provide excellent insulation and clear vision throughout their service life.

Ensure your Insulated Glass Units are up to code and built to perform with Azuma Design. Our testing services, aligned with AS4666 and EN1279 standards, provide peace of mind of a quality manufacturing plant and finished product, and long-lasting durability for your projects.
