ROOF MEMBER OR CEILING MEMBER, AND CONSTRUCTION
To provide a roof member or a ceiling member, which is capable of reducing cooling and heating energy consumption by reducing influent and effluent heat amounts between indoor and outdoor environments in such a situation that the indoor temperature is kept constant by use of cooling and heating equipment independently of the outdoor air temperature changes.Provided is a member for roofing or ceiling, including: an outdoor-side heat insulating layer (A); an indoor-side heat insulating layer (B); and a heat storage layer between the outdoor-side heat insulating layer (A) and the indoor-side heat insulating layer (B), in whichR ≤ 0.10 where R is represented by Equation (3):R=2R1−0.52+R2−12+R3−0.552R1=Tb/Kb/Ta/Ka+Tb/Kbwhere Ka is a thermal conductivity of the outdoor-side heat insulating layer (A), Ta is a thickness of the outdoor-side heat insulating layer (A), Kb is a thermal conductivity of the indoor-side heat insulating layer (B), and Tb is a thickness of the indoor-side heat insulating layer (B),R2 is a ratio of a latent heat amount of the heat storage layer in a temperature range of 15°C to 50°C with respect to a latent heat amount of the heat storage layer in a temperature range of -10°C to 60°C, andR3=L5/L20
