Method of heat-insulating and water-proof construction utilizing a roll having a web portion and a flap portion

Abstract

A method of constructing a heat-insulating and water-proof structure by employing a plurality of heat-insulating members utilizes a water-proof membrane which includes a plurality of membrane sections which are connected together and provided in a roll form. A first water-proof membrane section is placed over a heat-insulating member, and one longitudinal edge of the water-proof membrane section is bent about one longitudinal edge of the heat-insulating member and secured to a base surface. A second heat-insulating member is then laid on the base surface next to the first heat-insulating member so that the one longitudinal edge of the first water-proof membrane section is held between the first and second heat-insulating members. A second water-proof membrane section is placed over the second member, and one longitudinal edge of the second membrane section is bent and secured to the base surface, and this process is continued until the entire heat-insulating and water-proof structure is constructed.
