I am investigating the use of stucco masonry versus Exterior Insulation and Finish Systems (EIFS) in the construction industry. I have no knowledge or training in this matter and my knowledge is limited to what I have read in the past few days.
As I understand it, both stucco and EIFS have a long history in the building construction industry. I have also read that there are two type of EIFS, PB (polymer-based) and PM (polymer modified) systems widely used in the building construction industry.
Exterior Insulation and Finish Systems (EIFS)
Question: What are the moisture related issues in the of Stucco and EIFS with regards to mold buildup with respect to corrugated aluminum siding? Once again my primary interest is with to respect to moisture and mold.
