The lath in stucco, applied on a stud wall, must be backed by a water resistant layer?typically two layers of No. 15 roofing felt or one layer of No. 30 roofing felt. The assembly also requires an air-weather barrier (AWB). Explain why the roofing felt cannot function as an AWB in addition to providing water resistance. Which material is used as an AWB with stucco?
What will be an ideal response?
The roofing felts are 3 ft wide and their joints are not taped in order to allow vapor permeability through them. The
AWB used with OSB sheathing is a sheet membrane, either integral with OSB or separately applied. With glass-mat
faced gypsum sheathing, AWB is a liquid-applied film.
