Hybrid modified asphalt sheet that combines the advantages of the torch method and the self-adhesive method.
We would like to introduce "OS-sheets," a modified asphalt waterproof sheet handled by Robusto. The methods for asphalt waterproofing construction include the traditional hot method and the cold methods (torch method and self-adhesive method). "OS-sheets Z40" utilizes minimal use of a torch burner in the cold method, taking advantage of the thermal welding benefits of the torch method while also incorporating the high construction efficiency of the self-adhesive method. 【Cold Method】 ＜Torch Method＞ ■Features - A method where the back side of the modified asphalt roofing sheet is heated with a torch burner and applied while melting. - OS-sheets Z40 melts the sheet itself to weld the seams. *For more details, please refer to the PDF document or feel free to contact us.
