I know what azdel is, but what is TPO?
IMHO, no one really knows what TPO is… its been reformulated 4 or 5 times and you don’t know which formulation you have or are buying… each reformulation claiming to have corrected problems of previous versions… who knows when they will actually get it right or when a formulation will be around long enough to prove itself… older versions of TPO used on RV’s have caused extensive roof damage due to their fleece backing, wicking water to large areas…
I think the latest un-backed version of TPO for RV’s is only about 20mil, EPDM used by the RV industry is normally about 40 mil, and commercial grade EPDM is normally 60 mil… the new TPO might be the greatest product ever, only time will tell if it is or if there will be another reformulation coming…
