Behind exterior stucco or siding, a drainage gap or weep provision is often required so that:
a.Any water that gets behind the cladding can drain out and the wall can dry
b.The wall looks thicker
c.The cladding is heavier
d.The insulation R-value increases
Explanation
A drainage plane/gap and weeps let incidental water that penetrates the cladding escape and allow the assembly to dry, preventing rot and mold. It is not about appearance, weight, or increasing R-value.
