Why is it necessary to perform multiple tests after installation?

Performing multiple tests after installation is essential primarily to ensure compliance with varying industry standards. Different building codes and industry regulations set forth specific requirements for air barrier performance, leakage rates, and material effectiveness. By conducting tests, professionals can verify that the installation meets these standards, which is crucial for both safety and efficiency in building performance.

While confirming aesthetics, assessing environmental factors, and determining the longevity of materials are valuable considerations, they do not directly address the critical compliance aspect. The core objective of testing is to validate that the installation aligns with the stringent regulations and performance criteria that safeguard both the building's integrity and the occupants' comfort. This compliance helps prevent issues like air leakage, moisture infiltration, and energy inefficiency, ultimately leading to more sustainable and durable construction practices.
