Are there any special considerations for claddings such as conventional stucco or manufactured stone?
Yes. Because these materials are highly absorptive claddings, DELTA®-DRY is especially suited for use behind them. These materials tend to hold water and are therefore particularly susceptible to vapor drive from solar-driven moisture. DELTA®-DRY can significantly enhance the drying capacity of these systems. This is not the only special consideration. Many jurisdictions require the use of two layers of a weather resistive barrier (WRB) in these systems. When two layers of a WRB are required, it is best to put the DELTA®-DRY in front of the first layer and behind the second layer. Always check your local building requirements for the cladding materials selected.
