Testing Methods and Performance Requirements
| evaluations/product test results | |
|---|---|
| Building Envelope Testing | DuPont™ Tyvek® weather barrier and other DuPont weatherization products undergo vigorous building envelope testing in the laboratory and controlled environments, to help DuPont provide innovative solutions for the building industry. |
| Air Barrier Association Evaluation | The Air Barrier Association of America (ABAA) has an evaluation protocol for air barrier materials and assemblies that has been successfully completed by a range of DuPont™ Tyvek® materials. |
| Air Barrier Testing | While the air infiltration property of a material can be measured in the laboratory, installation methods and quality of workmanship in the field are critical to “whole-building air leakage.” Air barrier testing is a key to establishing the best installation methods for a system that will perform in real-world conditions. |
| Air Leakage Testing | In air leakage testing, DuPont™ Tyvek® commercial air barrier assemblies exceed Air Barrier Association of America ASHRAE 90.1 and IECC air leakage requirements, when tested in accordance with ASTM E2357. |
| NFPA 285 Compliance | All DuPont™ Tyvek® air and water barriers designed for commercial construction have been tested and shown to meet NFPA 285, the National Fire Protection Association fire performance standard for vertical wall assemblies. |
