• Space Assurance™ is a flexible, flame resistant polyester fabric used as a fastener line, assuring the proper detail between the wall & ceiling. Space Assurance eliminates a common path for noise flanking in multi-family construction.

    Flanking noise is often caused by improper detailing of the gypsum wall & ceiling. The proper detail is to leave a 0.125” space & then caulk the joint. This installation detail is difficult to install & difficult to assure.

    The first step in ceiling installation is to install Space Assurance™ around the plate in each room prior to installing resilient channels. Ceiling elements butt against the Space Assurance™ with the bottom half used to separate the ceiling drywall from the wallboard. The excess is cut off.
