Standard Installation
<-- Return to Previous Screen

Place leaded side of drywall against studs. Drill pilot holes 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. The contractor must protect installed material from damage by other contractors, and 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.
