摘要

In building roof slope and roof material [challenge] of various design exists typological, and that it provides a multi-layer waterproof sheet that can be used as a waterproof sheet to the wall and toe portion of the roof. Bonded on the surface of the aluminum foil 3 using an adhesive 2, on the back side of the aluminum foil 3, and was coated with resin coating 4, an elastomeric sheet 1 having a heat-shrinkable and tear [SOLUTION] resistance I is characterized by. According to the multilayer waterproofing sheet EFFECT invention, the elastomer sheet having a tear resistance and heat-shrinkable, is bonded to the surface side of the aluminum foil using an adhesive, on the back side of the aluminum foil, resin Since coating the paint, by the four-layer structure of the elastomer sheet, aluminum foil, adhesive-resin-based paints, also has both bending workability and durability. Therefore, in building a variety of roofing materials and roof slope of the design are present in typological, as installation of waterproof sheet to the building and the wall of the roof is compatible with field installation shape, suitable for use in waterproof sheet for roof is.
