PROBLEM TO BE SOLVED: To provide a heat insulating panel superior in heat insulating property, lightweight, highly strong, more durable, good in nailing machinability with no strength degradation and deformation under water absorbing conditions and air temperature variations, and usable as a construction material, a structural member, a heat/cold retaining material and a packaging material. SOLUTION: The heat insulating panel 1 as a lightweight cement panel is such a porous molded product 2 that a kneaded material formed by kneading preformed foam of cement, water, reinforcing fibers and foaming agent is filled in a sealed cement mold, cured and solidified. The porous molded product 2 contains the reinforcing fibers and the foam in a dispersed condition. A plurality of parallel cavity portions 3 are formed therein passing from one side end face to the other side end face. COPYRIGHT: (C)2009,JPO&INPIT |
