How to build the perfect wall:
Four principal control layers for a wall:
- a rain control layer
- an air control layer
- a vapor control layer
- a thermal control layer
Residential wall.
Commercial Wall
Simplified wall:
Cladding - aesthetics, and UV protection.
Control layers OUTSIDE of structure, otherwise you trap moisture, and create mold.(Vinal wallpaper would trap moisture - use latex paint)

90% of the problems happen where the roof meets a wall, or around windows, because of continuity issues.
Window: has to do everything a wall does, and more.
