INSTALLATION INFORMATION FOR LEAD LINED DRYWALL (LEAD LINED SHEETROCK, LEAD LINED GYPSUM WALLBOARD)
Lead Lined Drywall (lead lined sheetrock, lead lined gypsum wallboard) consists of a single unpierced sheet of lead laminated to the specified thickness of drywall. The bonding is accomplished with a continuous layer of mastic adhesive. We recommend using 5/8” drywall to support the extra weight of the lead.
The Lead Lined Drywall (lead lined sheetrock, lead lined gypsum wallboard) should be fastened at a minimum of 8" on center at the edges of each sheet, and at a minimum of 12" on center at the intermediate studs with normal drywall screws. 2" wide strips of sheet lead of the same lead thickness should be applied to each of the joint studs using a standard type of construction adhesive, prior to installing the Lead Lined Drywall (lead lined sheetrock, lead lined gypsum wallboard). These strips of sheet lead will provide the necessary 1" overlap with the adjoining sheets. Each fastener will be covered with a lead disc 3/8” in diameter and equal in thickness to the lead laminated to the sheetrock to eliminate the possibility of radiation leakage at the point of fastening. They should be applied using a fast drying construction adhesive. FOR LEAD THICKNESSES THAT EXCEED 1/8” PLEASE REFER TO OUR LEAD LINED PLYWOOD PAGE.
