Are there moisture intrusion standards?
Yes. There are Building Official Codes (Uniform Building Code [International Conference of Building Officials] + Local Codes), and governmental standards (state and federal associated with energy, plus 24CFR3280 – HUD Code) as well as manufacturer installation requirements, owner use limitations, and fundamental design principles that are standard to the building industry. Standard setting bodies such as ASTM with Standard such as E- 2266-04 and E-241-04 continually offer guides to minimize moisture intrusion.
