Fire Rated Wall Assemblies

UTIL-A-CRETE® backerboard units have been approved for use in construction which requires a fire-resistant rated wall. A one-hour rated wall assembly consists of 20-gauge 3-1/2" steel studs, one layer of 7/16" UTIL-A-CRETE® on one side and one layer of 5/8" type X gypsum wallboard on the opposite side, with mineral fiber insulation batts in the stud cavities. Uniquely, this rating was achieved without any facing material (e.g., ceramic tile or marble) over either the UTIL-A-CRETE or gypsum board, which allows the owner, architect or contractor greater flexibility in designing the finished surface, while retaining or even enhancing the one-hour rating. (Tests were conducted pursuant to ASTM E-119-83, as a non-load-bearing wall, fire-rated both sides, under the supervision of Construction Technology Laboratories.)
