Anotácia

This specification covers prefabricated, self-adhesive, polyester fabric reinforced, polymer-modified asphalt surfaced roll roofing products, with granule surfacing, designed for steep slope applications. These products use polymer modifiers in their top and bottom coatings and have an adhesive bottom layer which is exposed by removal of a peel-away protective release paper or film sheet. The specified tests and property limits used to characterize the sheet materials are intended to establish minimum properties. The minimum physical properties required for the sheet include thickness, peak load, elongation, tear strength, adhesion to plywood, side lap integrity, thermal stability, and granule loss.
