On many Canadian projects, independent testing agencies are engaged to verify the performance of installed window and façade systems.
These 3rd party site tests are typically required by:
• Consultants and building envelope specialists
• Project specifications
• Quality assurance protocols
Common testing standards include:
• ASTM E1105 – Water penetration
• ASTM E783 – Air leakage
These tests assess how systems perform after installation, under real site conditions.
Independent testing provides:
• Objective verification of installation quality
• Early identification of deficiencies
• Confidence for owners, consultants, and contractors
It ensures that systems are performing as intended within the overall building envelope.
