General strategies:
• keep water out
• let water out if it gets in
Strategies:
- always place the moisture retarder close to the warm side of the your wall assembly
- these thermal insulation, multiple glazing and thermal breaks to keep interior surfaces at temperatures above the air dew point
- use warm side vapor retarder to keep air from which surfaces and spaces that are cold enough to cause condensation
- always ventilate part of the wall assembly that lies on the cold side of the vapor barrier
- where condensation is likely to occur provide gravity driven systems to catch and remove water
