A sealing material may be located between the gypsum liner panels and the structural elements, and between adjacent ones of the structural elements. The sealing material may form seals therebetween, such that the ASW is substantially airtight when assembled. In addition, the ASW may include a fire rating of at least 2 hours in compliance with ANSI/UL 263.
