Envelope Performance Testing

Envelope performance testing evaluates how well an envelope—such as a building’s window or door system—resists air and water infiltration, as well as its structural strength and durability. The test simulates real-world conditions like wind, rain, and pressure to ensure the envelope maintains its integrity and energy efficiency over time. This helps manufacturers and builders confirm that these components meet safety, weatherproofing, and energy standards, ensuring reliable performance and occupant comfort.
