Lead Drywall: also referred to as Lead-Lined Sheetrock, Gyproc, Wallboard or Lead-Lined Gypsum Board.
MarShield’s drywall is laminated with sheet lead that is designed to cover necessary surfaces or walls in a room requiring radiation shielding. It is affixed to surfaces or walls ensuring a continuous layer of sheet lead under the drywall to a specified height. It is used in new construction or shielding upgrades/renovations
MarShield starts with a piece of sheet lead which meets or exceeds Federal Specifications QQ-L-201F, Grade C, ASTM B-749-03, and Standard Specification for lead and lead alloy strip, sheet, and plate products. The lead sheet is 99.9% pure or better of un-pierced virgin lead, free of dross, oxide inclusions, scale, laminations, blisters and cracks and is factory laminated to drywall.
All of our leaded drywall product is furnished as type “X” fire code in 1/2″ to 5/8″ thickness with a lead thickness of 1/32″ to 1/8″ maximum thickness. The drywall conforms to ASTM C36 and Federal Specifications QQ-L-201 F, GRADE C, ASTM B-29. Pure lead sheet meeting Federal Specification QQ-L-201 F, Grade C and ASTM B749-03, Type L51121 is factory laminated under pressure to the back side of the drywall panel. Our lead drywall product meets U.S. and Canadian Safety Standards for 1 hour and 2 hour fire-rated partition applications.
Lead is factory pressure-laminated and adhered to the drywall with permanent adhesive in 48″ widths, equal to the width of the drywall, or in 49″ widths giving the lead a 1″ overlap at the vertical drywall joints. Due to the excessive weight, our drywall panels can be customized to smaller widths and lengths to suit most applications. 2″ wide batten strips can be supplied to cover all vertical joints where applicable. Smaller panels will require more batten strips but the ease of handling these lighter panels will be offset in the extra cost and labor during the installation process.
