Entrepreneurs selling plywood made some quick bucks in advance of Hurricane Ike, but a better option for homeowners may be temporary polycarbonate glazing. The newest product from SABIC Innovative Plastics is Lexan LTH3T16 sheet, a 5/8-inch-thick, fluted polycarbonate storm panel targeted for use on windows and doors. It is said to be four times stronger than half-inch plywood sheet and offers 250 times higher impact resistance than glass and 30 times the impact strength of acrylic of the same thickness. The sheet can be easily cut to size using conventional power tools to cover windows and doors. The PC lets in light and can be left on for the duration of a hurricane season.
