SHINGLE WITH FILM COVERED SURFACES

摘要

An asphalt-based shingle is formed with a substrate saturated with asphalt, an asphalt coating on the saturated substrate, and a top film bonded to the surface of the asphalt coating covering at least a portion of the shingle to be exposed when installed, The top film may be configured to mimic the appearance of traditional clay granules on the shingle or another shingle surface. More specifically, the top film is printed or coated with an image that mimics the appearance of a clay granule bed and is embossed, pressed, or molded to mimic the texture of a clay granule bed. The top film is UV resistant to protect the asphalt below from deterioration. An anti-stick film may be bonded to the back of the shingle to prevent shingles from sticking together when stacked into a bundle. A method of fabricating the shingle may include applying pre-fabricated film to the shingle substrate during shingle manufacturing or extruding a polymer film onto the substrate and subsequently printing and embossing the film during shingle manufacturing.
