In the figure, an indoor ski resort 1 includes a floor 4 formed on pillars 3 erected on a base ff12, walls 5 erected on both sides of the floor 4, and a frame on the upper end of the wall 5. It is composed of a roof section 6 that is extended. Indoor Niski maintains the indoor temperature at a low temperature of -3 to -5 degrees Celsius, and uses a snowmaking machine to deposit 20 to 50 mouths of snow on the floor to form a ski slope. At the indoor Niski resort, the air space in the building is at a high temperature (30 to 43 degrees Celsius in the summer).In order to insulate heat from entering the building from the outdoors, the floor 4, walls 5, and roof have an insulating structure. There is a need to. In particular, the floors of indoor ski resorts are covered with snow mats (artificial turf-like material made of short fibers flocked to drainage mats) to prevent snow from slipping, and waterproof sheets that form drainage gutters. snow is piled up on top of it. When snow is used for downhill skiing, the surface of the snow gets dirty, so it is necessary to pile up new snow on top of the dirty snow and melt the snow at the bottom to regenerate the snow. Therefore, the top of the sheet waterproof layer that forms snow mats and drainage gutters is always covered with water, so if water leaks from the sheet waterproof layer or moisture barrier layer and enters the insulation material, the insulation ability of the insulation floor will decrease. Insulated floors must be moisture resistant. JP-A-60-17642 No. 11 A sheet moisture-proof layer with aluminum foil or a non-foamed film is pasted on the insulation material (polystyrene foam board) used for the walls of refrigerated warehouses to prevent water vapor from penetrating into the insulation material.
