ROOT ISOLATION SHEET FOR ROOF, ROOF COMPLEX WATERPROOF AND ROOT ISOLATION LAYER STRUCTURE USING ROOT ISOLATION SHEET, EMBOSSING POLYVINYL SHEET AND RUBBER-ASPHALT MEMBRANE WATERPROOFING MATERIAL AND METHOD THEREOF
ROOT ISOLATION SHEET FOR ROOF, ROOF COMPLEX WATERPROOF AND ROOT ISOLATION LAYER STRUCTURE USING ROOT ISOLATION SHEET, EMBOSSING POLYVINYL SHEET AND RUBBER-ASPHALT MEMBRANE WATERPROOFING MATERIAL AND METHOD THEREOF
A root-isolation sheet for a roof, a roof complex with a waterproof and root-isolation layer structure using the root-isolation sheet, an embossing polyvinyl insulating sheet, and a rubber-asphalt membrane waterproof material, and a method thereof are provided to safely utilize a building against penetration of plant roots and water leakages by using a waterproof and root-isolation material in vegetating on the roof of the building and to thereby protect the building against the plant roots. A root-isolation sheet for a roof is composed of three layers: a PVC(Polyvinyl Chloride) layer as the lowermost layer; an oxidized aluminum layer as the next lower layer; and a PVC layer on the next layer. The root-isolation sheet is produced in a large quantity as a shape of a roll or a plate to easily construct vegetation on the roof. Thickness of the root-isolation sheet is 0.5~0.8 millimeters to satisfy the root-isolating function and easily construct on the roof, but desirably 0.8 millimeters to exert the root-isolating function best. The lowest limit to exert the root-isolating function is 0.5 millimeters. The construction property is shown highest at the thickness 0.5 millimeters.
