Moisture Control

摘要

Among all the challenges plaguing buildings in the U.S., moisture-related problems are at the top of the list, according to the authoritative Whole Building Design Guide. About 80% of all premature facility-wear expenditures stem from poor moisture control, note building scientists at Cleveland's C.L.I. Group. "Water in liquid and vapor states and temperature changes have long been recognized as the most destructive weathering elements affecting the entire building envelope, especially exterior walls," says Syracuse, N.Y. -based Peter J. Arsenault, AIA, LEED AP. "Accordingly, moisture management and thermal efficiency are critical keys to a successful exterior wall system."
