Protective Wall Systems


Ray-Bar Lead Backed Gypsum Wallboard is furnished as 1/2" and 5/8" Fire code gypsum board meeting Classification ASTM C 36, with pure lead sheet meeting Federal Specification QQ-L-201 f, Grade C, factory laminated under pressure to the back side of the gypsum panel. Custom manufactured to customers specifications, typically available in one day/next day. Shielding accessories for installation include a 2" wide lead batten strip for vertical joints and corners along with lead tabs or lead discs for screw penetrations, lead head nails for wood stud installations and sheet lead for backing and shielding of cut-outs for electrical, plumbing, medical gas or other penetrations. Sheet lead backing must be equal or greater value as the lead in the wall partition that penetration occurs in. For listing of In-Stock lead thickness' available, see 'Ray-Bar Sheet Lead Thickness Chart.' For specifications, see 'Ray-Bar Lead Backed Drywall Specification.' Shielding requirements should be determined by a qualified health radiation physicist, See 'Shielding Information.'

Protective Wall Systems

Ray-Bar Fire-Rated Lead Backed Gypsum Wallboard (Type RB-LBG) also available as U.L. Labeled and Classified to U.S. and Canadian Safety Standards for 1 hour and 2 hour fire-rated partition applications (See complete marking on product) in 8 standard lead thickness shielding values from 1/64" and up to 1/8" and minimum 7'0 (84") high and approved in 12 unique wall partition designs and many combinations on over 7 different wall board types where two or more protective/fire-resistant and additionally moisture-resistant, mold-resistant, abuse-resistant, security or other applications available as required or specified by your project architect, or contact us directly for additional proprietary information.
