Abstract: The condensation resistance of fenestration products is typically determined in standard tests with air leakage eliminated by sealing the cracks and balancing the pressure difference across the test specimen. In reality, ...

Abstract: The fan pressurization method for measuring air leakage through the building envelope relies on the assumption that the extraneous air leakage (EAL) through paths other than those through the specimen being tested is ...

Abstract: Rainwater penetration is the source of moisture that causes the greatest damage to building envelope assemblies. The building envelope should be designed to reduce the amount of rainwater penetration by deflection and ...
