Installation:
Place leaded side of drywall against
studs. Drill pilot homes for screws to prevent deformation of lead. A
minimum lead overlap of one inch is required at all joints and corners.
Extend lead overhang at least one inch into all frames or openings. Fasten
lead lined drywall to studs with screws placed eight inches on center.
Cover each screw that penetrates the leaded area with a lead disc. Dimple
leaded drywall and glue lead disc to screw head. Install sheet lead over or
behind all penetrations cuts, or punctures to ensure continuity of radiation
shielding.
Drywalls can be taped, floated and
finished as required. Protect installed material from damage by other
construction. Have shielding tested by approved personnel. Shielding must
comply with all federal and state regulations.
Note: For lead thickness up to 5/64"
(5#), a two inch lead overhang extends off one side of leaded drywall to
serve as a batten strip. If lead thickness exceeds 5/64" (5#). a two inch
lead batten strip will be supplied for each piece of lead lined drywall.
Batten strips are required at all drywall joints.
