<p><P>PROBLEM TO BE SOLVED: To solve problems of a conventional sash wherein the weight of the sash is increased since a three-layer pane having high heat insulation performance and high effect of preventing dew condensation in winter is used, and a crime prevention film is easily scratched. <P>SOLUTION: The three-layer crime prevention sash of high-heat insulation resin is reduced in weight and made hard to be scratched by pasting the prime prevention film on the inside of a three-layer pane and forming the intermediate layer of the three-layer pane in a plastic layer such as a CD case. By pasting the crime prevention film on the pane, the required strength of the sash can be obtained even if the thickness of the pane is reduced, and the sash can be further reduced in weight and increased in strength. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
