I keep seeing so many stories about fiberglass walls delaminating and the such with luan as part of the construction. I see people who don't even have water damage and the walls are coming apart. So...
I keep hearing good things about Azdel and some prominent names in the industry use it.
Would not be a deal breaker in my personal experience and that being.....have never had a single delam issue in 4 fiberglass trailers and previous trailer was 10 yrs old when sold.
Have seen many delamination in trailers sitting in permanent locations with the likely culprit being water intrusion and lack of preventative maintenance.
