ROOF-DAMPPROOF SHEET

摘要

PURPOSE: A roof-dampproof sheet is provided to asphalt a steep roof safely and rapidly. CONSTITUTION: The roof-dampproof sheet(20) comprises an asphalt layer(22) attached to the upper part of a roof structure to have dampproof/waterproof functions, an adhesion-proof layer(21) attached to the lower part of the asphalt layer(22) to be separable to prevent the adhesion between sheets or impurities while carrying a sheet, and a non-skid instrument(23) provided with many projections to increase a contact area of an adhesive and to prevent from sliding when attaching/fixing roof materials on the sheet.
