DuPont™ Tyvek® StuccoWrap® WRB is the perfect weatherization barrier for stucco façades. Because Tyvek® is inert, contact with stucco materials does not compromise its weather barrier capabilities. Unlike Grade D paper, Tyvek® StuccoWrap® does not absorb moisture from the stucco mix. This contributes to proper curing, minimizing cracks and producing a stronger façade. And Tyvek® StuccoWrap® WRB is engineered with a grooved surface that acts as a drainage plane, resulting in better water management when installed as part of a two-layer system. With these advantages, it’s no wonder that Tyvek® StuccoWrap® helps promote stronger stucco façades and better performing wall systems.
