ASTM Building Envelope Standards
Standards for drainage, weather-resistant barriers, and building envelope systems
Last updated: September 21, 2025
Overview
ASTM Building Envelope standards provide comprehensive testing and performance requirements for materials and systems that protect buildings from water intrusion, air infiltration, and environmental damage.
These standards cover weather-resistant barriers (WRB), drainage systems, flashing materials, and integrated building envelope assemblies that work together to maintain building integrity and energy efficiency.
Key Standards Areas
- Weather-resistant barriers and building wraps
- Drainage mat systems and rainscreen assemblies
- Window and door flashing systems
- Water-resistive coating systems
- Air barrier materials and assemblies
Key Testing Standards
Water Penetration Testing
ASTM E331, E547, and E1105 for water resistance evaluation
Air Barrier Performance
ASTM E2178 and E2357 for air leakage and assembly testing
Drainage Efficiency
ASTM E2273 and E2925 for drainage mat and rainscreen systems
