Understanding the importance of IGU certification for imported windows in the US and Canada

In modern window construction, insulating glass units (IGUs) are essential for achieving superior thermal performance, sound insulation, and overall structural integrity. An IGU consists of multiple glass panes, typically two or three, separated by a spacer and sealed around the edges to create a hermetically sealed cavity. This cavity is filled with inert gases such as argon or krypton, which significantly reduce heat transfer compared to regular air. The sealed unit minimizes thermal conductivity, thereby enhancing energy efficiency by reducing heat loss in the winter and heat gain in the summer.


To ensure compliance with stringent American and Canadian building code requirements and optimize long-term durability, IGUs incorporated into windows destined for the US and Canada must comply with the standards outlined in ASTM E2190 and CAN/CGSB-12.8 specifications. This certification process is paramount in verifying the unit’s capacity to withstand the diverse weather conditions while delivering the expected thermal resistance, air leakage, and structural integrity.


There are several programs offering IGU certification that are supported by Fenestration and Glazing Industry Alliance (FGIA):
 

  • ALI/AAMA Sealed Insulating Glass Certification Program
  • IGMAC Certification Program
  • IGCC/IGMA Insulating Glass Certification Program.

Benefits of IGUs certification

 

  • Quality Assurance: Certification provides assurance that the IGUs meet high standards for quality and performance, reducing the risk of premature failure and maintenance issues.
  • Compliance with Building Codes: certified IGUs are recognized as meeting key building code requirements in Canada and the US, ensuring compliance with local and national regulations.
  • Market Acceptance: Products with Insulating Glass Units certification are widely accepted and trusted in the construction industry, making them preferable for architects, builders, and consumers.
     


By obtaining glass units certification, manufacturers demonstrate their commitment to producing high-quality IGUs that meet the demanding standards of the fenestration industry. These certifications are an important factor for anyone considering importing windows and doors and using IGUs in the Canadian and the US market.
