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.
