<p><P>PROBLEM TO BE SOLVED: To minimize the lowering of heat insulating property of a member for construction using vacuum insulating materials by cutting the unnecessary part thereof. <P>SOLUTION: In this member 10 for construction, the vacuum heat insulating materials are disposed in an internal space between surface materials facing each other, and a foam insulating material 13 is charged therein and foamed. Each of the vacuum insulating materials 12 is composed of a normally vacuum heat insulating material 17 in which one core is depressurized and enclosed and a surface seal vacuum insulating material 14 formed by depressurizing and enclosing divided cores divided into multiple parts one by one in independent spaces independent of each other. The entire sizes and shapes of the vacuum insulating materials 12 are generally the same. The surface seal vacuum insulating material 14 is disposed adjacent to the outer peripheral edge of the member 10 for construction at the corner part where the possibility of cutting of the material is relatively high. Since a vacuum break is produced by cutting only in a part of the surface seal vacuum insulating material 14, the lowering of the heat insulating property thereof by the cutting of the unnecessary part can be minimized. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
