Patent ID: 7637074

Claim:
A storm panel, comprising: a polymeric sheet having an arced geometry with an amplitude of greater than or equal to about 1.27 cm, the polymeric sheet comprising a polymeric substrate layer having a top surface and a bottom surface; a polymeric top layer disposed adjacent to the top surface, wherein the top layer comprises a top layer ultraviolet light stabilizer; a polymeric bottom layer disposed adjacent to the bottom surface, wherein the bottom layer comprises a bottom layer ultraviolet light stabilizer; wherein the storm panel has a uniform thickness; wherein the storm panel exhibits less than or equal to about 4.0% haze as tested via ASTM-D1003-00; and, wherein the storm panel exhibits a yellowness index shift that is less than or equal to about 9.0 after 1,500 simulated hours of aging at an irradiance of 0.55 W/m 2/ nm and 60° C., as measured via ASTM D1925-70.
