No. TVM Draft Stop may only be used as a FireStop in Non-Rated Construction. Two ASTM Test Methods have been developed for FireStops. ASTM E814 has been developed for Fire-Rated Construction while ASTM E136 was developed for Non-Rated Construction. TVM Draft Stop has only passed ASTM E136 and therefore may only be used as a FireStop in Non-Rated Construction. Remember, TVM Draft Stop may be used as a sealant in other areas where high temperature resistance is necessary.
