Product Description, Applications

DensGlass Ultra Shaftliner incorporates a moisture- and mold-resistant, non-combustible gypsum core with coated fiberglass mats to resist exposure to the elements during the early stages of the construction cycle and is backed by a 12 month weather exposure limited warranty. It is the perfect substitute for heavy, expensive masonry construction, or paper-faced shaftliners and provides an STC rating of 60 as part of an insulated separation or firewall assembly.
