FIRE-RESISTANT, SELF-ADHESIVE ROLLED ROOFING MEMBRANE AND METHOD OF MAKING SAME

摘要

A fire resistant, self-adhesive rolled roofing membraneis used on low sloped roofs for insulating a surface fromweather. The roofing membrane includes an asphalt-saturatedfibrous material having a roofing surface area, for example,roofing granules on a portion of the top surface and a cleansurface area on another portion of the top surface. Theroofing membrane includes an adhesive surface area on aportion of the bottom surface opposite the roofing surfacearea and a parting agent covered surface area on anotherportion of the bottom surface generally opposite the cleansurface area to prevent adhering to the clean surface areawhen rolled. The adhesive surface area includes a layer ofself-adhesive material, such as rubberized asphalt, capableof adhering to the clean surface area when strips of theroofing membrane are overlapped. The adhesive surface areais covered with a release backing to prevent adherence tothe roofing surface area. The fibrous material is saturatedwith an oxidized asphalt with mineral filler and therubberized asphalt adhesive material is minimized to providefire resistance.
