This wall can be increosed to a 2 hour frre <br /> wall by installing an additional loyer of 5/8" type "X" drywall on one side (the additional <br /> drywall layer needs to run perpendicular to the existing drywall sheets with al! of the seams <br /> taped and mudded. Also, ihe two layer system needs to run from the concrete slab on grade <br /> up to the underside of the existing roof deck sysiem.). <br /> Attach the additional drywall layer with 1 S/8" long drywall screws spaced at 12" on center. <br /> Shoufd you have any questions, please let me know. <br /> Sincerely, <br /> �` <br /> _V <br /> ich�rd L.
