Abstract
An exterior heat insulation panel is disclosed which uses vaporization heat of water. The exterior heat insulation panel is installed on the surface of a roof or walls of a structure and is used for cooling and air-conditioning of structures, particularly, to an exterior heat insulation panel which can achieve high efficiency and energy-saving. The exterior heat insulation panel includes a surface layer having a continuous capillary tube structure and a non-capillary tube void structure made of porous aggregate combined by a hydrophilic binding component, and a foamed organic resin type of heat-retaining board having closed pores. The heat-retaining board and the surface layer are integrated by compression molding.
Claims8
An exterior heat insulation panel installed on the surface of a roof or walls of a structure, the exterior heat insulation panel comprising:
- a surface layer having a continuous capillary tube structure and a non-capillary tube void structure, the continuous capillary tube structure being made of particles of porous aggregate combined by a hydrophilic binding component and the non-capillary tube void structure being formed between the particles of the porous aggregate;
- and
- a foamed organic resin type of heat-retaining board having closed pores,
- wherein the heat-retaining board and the surface layer are integrated by compression molding and
- wherein the porous aggregate having an average particle diameter of 1 mm to 8 mm is mixed with the binding component and subjected to the compression molding, and the volume ratio of the binding component to the porous aggregates is 0.05 to 0.6.
