This specification covers glass felt impregnated with coal tar intended to be used with coal tar pitch in the construction of built-up roofs and waterproofing systems. The felt shall be a thin, porous sheet of uniformly distributed glass fibers, with or without the addition of reinforcing stranded glass yarns, and bonded with a water-resistant resinous binder. Longitudinal and transverse breaking strength, pliability, width, area, net dry mass, parting agent and stabilizer content, moisture content, desaturated mass, bituminous saturant (coal tar) content, and ash content are among the property requirements to which the glass felts should conform to.
This standard is referenced in the 2012 International Building Code® and the International Residential Code®.
