The most expensive of the screens and panels, with a five year warranty, Polycarbonate is worth every penny. It is extremely tough and virtually unbreakable, and is often considered as the best, strongest, shatterproof “glass” application. While it is very tough, it also scratches fairly easily and common cleaners can ruin the surface (it must be handled with care). http://www.americanmarinecoverings.com
