Samples of sealant used on a structure exposed to temperature extremes between -6°F and 90.5°F, and solar radiation (annual average) of 1,100kWh/m2 between 1985-2010 were tested. The 25-year old sealant passed ETAG 002-1 testing standards showing it could last an additional 25 years, a total of 50-years service life.
