Building Enclosure Field Testing

Testing on materials, products, and mock-ups can provide you invaluable data before your construction project begins, but the whole is greater than the sum of its parts. Whether you need assistance with problem resolution or simply to ensure the quality of your products and systems, we can be there to help you all along the way. We have teams equipped to test Air Infiltration, Water Leakage, Structural Performance, Roof Flood Testing, and Air Barrier in the field. We will ensure the appropriate test procedures are applied, while making modifications or developing custom testing to fit your specific needs. To devise the best chamber test arrangement, our work begins before we arrive at your job site. We carefully communicate with you to evaluate architectural details, shop drawings, and preliminary photographs to ensure the appropriate test procedures are applied. We take care of test equipment, equipment calibration, staging, access equipment and sffolding to ensure work proceeds smoothly. If required for specific projects, Intertek will modify standard procedures to test in accordance with project specifications.
