The protective coating on Strataglass is uniquely resistant to today's harsh environment. Industrial fallout - power, steel, chemical, paper, plants, jet exhaust and acid rain - are realities anywhere on our waterfront. Our coating prevents these elements from leaching into the vinyl. The results of leaching can be spotting, hazing, "orange" corners, and gray lines in the vinyl, to name a few. Strataglass resists these elements to give you a cleaner, longer life expectancy for your vinyl.
