Lead-Lined Drywall | California

for gamma and X-ray Shielding

serving Los Angeles, San Diego, San Francisco, Bay Area, Sacremento, California

Lead-lIned drywall from Direct ScientificSheetrock, gypsum drywall panels are pressure laminated with a permanent adhesive to lead sheets and arranged to provide effective radiation shielding through all joints. Lead lined drywall panels are secured to studs with drywall screws and covered with a lead disc. The lead thickness must be greater than or equal to the attenuation level specified by a health physicist. With every order, strips and discs are included. For quotations on leaded drywall, please contact us: tel: 310-589-0601, email: sales@drct.com.


Standard 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 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.

Drywall 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.
