EIFS on CMU in Florida?
I’m new to Florida where most exterior walls are CMU. I thought EIFS would help keep heat out while the interior would stay cool from CMU’s thermal lag.
I have heard a lot of negative comments about EIFS here and many say it can’t be used in Florida due to the humidity and rainy season. Few are familiar with drainable EIFS which I thought would help with the moisture/mold concerns people have. There are drainable impact EIFS products available so hurricanes are not a problem.
Typically builders put insulation inside the CMU walls which negates the benefit of CMU’s thermal lag although it still does a decent job of insulating.
Is EIFS a bad idea in Florida or do I need to do some educating?
