ABSTRACT:
The present invention relates to a heat-insulating panel formed of curly contracted pieces of tapes, for example thermally contracted pieces of magnetic tapes, and a method of manufacturing such a panel. In particular, the present invention concerns a heat-insulating panel which also serves as a concrete form. The heat-insulating panel has excellent strength characteristics such, as bending strength and bending rigidity, and dimensional stability, as well as characteristics of sound absorption, heat-insulation, electrostatic shielding and electromagnetic wave absorption, and is usable for a concrete form when placing concrete during the construction of a building formed of reinforced concrete or steelframe reinforced concrete. The present invention relates also to a method of manufacturing the panel.
