Lead-Lined Gypsum Board
Lead sheet laminated to Type X gypsum board, 4 ft widths up to 12 ft, for X-ray and imaging room shielding.

Overview
Lead sheet laminated to Type X gypsum board, 4 ft widths up to 12 ft, for X-ray and imaging room shielding.
Mayco Lead-Lined Gypsum Board, also known as leaded drywall, is constructed of a single roll of our own lead sheet meeting federal specification QQ-L-201 F or ASTM B 749-03 for lead that is laminated to fire code (Type X-Ray Shielded Gypsum) gypsum board meeting classification ASTM C 1396. Because our lead-lined gypsum board complies with all relevant guidance and regulations, it can be used in many different construction projects where shielding is required. Used in place of regular drywall, our lead-lined board provides excellent radiation shielding. Gypsum Board Sizes: 4 ft X 8 ft, 4 ft X 9 ft, 4 ft x 10 ft, 4 ft x 12 ft Standard Lead Sheet Thickness: 1/32 in, 3/64 in, 1/16 in, 5/64 in, 3/32 in, 1/8 in
Custom thicknesses and heights are available upon request. Lead thickness greater than 1/8” should be on lead-lined plywood.
