震性にも勝れる。(1) Since the heat insulation layer and the layers below are sequentially stacked on the body to be waterproofed via the base material and the base material, it is possible to lay these layers flatly and firmly on the body to be waterproofed. Moreover, since it is possible to absorb and mitigate vibrations such as an earthquake and prevent the waterproof frame and the heat insulating layer from being displaced or separated from each other, it is also excellent in earthquake resistance.

る。(2) Since two heat insulating layers are formed on the upper and lower sides, and a waterproof layer is provided between these heat insulating layers, the upper heat insulating layer blocks the solar heat, and the lower heat insulating layer prevents the waterproof frame from being exposed. By shutting off the heat from the above, heat from any direction can be prevented from being transmitted to the waterproof layer, and the deterioration of the waterproof layer due to heat can be reliably prevented. Since it can be efficiently prevented from being transmitted to the waterproof skeleton, not only can the deterioration of the waterproof skeleton due to solar heat be reliably prevented, but the evaporation of water from the waterproof skeleton due to solar heat can be suppressed, Swelling and floating of the waterproof layer and heat insulation layer due to vaporized water,
It is possible to reliably prevent peeling of the joint portion.

しないため耐久性が大きい。(3) Since two waterproof layers are provided between the two heat insulation layers and a reinforcing cloth for expansion and reinforcement is interposed between these waterproof layers, not only the waterproof effect is very large, but also by the cloth. Due to the reinforcing effect, expansion and contraction of the waterproof layer is unlikely to occur, and peeling between the layers due to expansion and contraction or displacement does not occur, resulting in high durability.
