<p>PURPOSE:To provide an enhanced antifreezing effect and to enhance fittedness and removability by forming a window cover whose portion of contact with a glass surface is formed into a sheet shape from an ether type polyurethane of specific hardness. CONSTITUTION:A window cover is either formed of a single sheet-shaped material 1 or formed by Iaminating the material 1 with a surface protective sheet 2 such as rubber or a metal and forming its portion of contact to a glass surface into a sheet shape from an ether type polyurethane having a hardness JIS(A) of 30 deg.-50 deg.. The window cover closely sticks to a windshield with its own stickiness, and shuts off outside air with the excellent heat insulating property of the above materials, thus providing a high antifreezing effect.</p> |
