Test of a Polyester Composite Wall Panel for Moisture Accumulation and Potential Removal of Moisture Through Venting.

摘要

A polyester composite exterior wall panel was exposed to accelerated winter temperature and humidity conditions for the purpose of determining performance with respect to moisture accumulation and release as a result of pressure and temperature differences. No moisture condensation within the wall system was detected from visual examinations made at various times of the testing period;no significant increase in gross weight of the wall was found from the direct weighings of the wall system. Results also indicate that a wet insulation in such a wall system is unlikely to be dried out by natural thermal action and convective motion.
