<P>PROBLEM TO BE SOLVED: To provide a heat insulation material for a wooden framework structure which can be easily and surely inserted between any vertical frame materials having different inner dimensions only by preparing one kind of heat insulation material made of a synthetic resin foam at a construction site, even when the frameworks constituting a part of a floor, ceiling, or roof of a dwelling house constructed as a wooden framework structure contain different inner dimensions between vertical frame materials. <P>SOLUTION: A heat insulation material 10, which is made of a synthetic resin foam, is inserted between vertical frame materials in a framework for a floor, ceiling, or roof of a wooden framework structure using a square bar of a breadth B and a depth K(>B) as a base material, with a standard inner dimension between the vertical frame materials being A, a first non-standard inner dimension being Ax(=(A+(K-B)/2)). The breadth a1 of a front face side is smaller than the Ax and the breadth a2 of a rear face side is larger than the Ax. The heat insulation material 10 has one or more V-shaped division grooves 21 to 23 extending longitudinally and opened toward rear face sides, and a partial heat insulation material 50 having a different breadth size is obtained by removing a part of the heat insulation material from any of the V-shaped division grooves 21 to 23. <P>COPYRIGHT: (C)2013,JPO&INPIT |
