Standard Installation Instructions

Pitts Little Corporation Lead Sheets are an ideal solution for your radiation shielding needs. Our sheet lead meets and exceeds Federal QQL-201 and ASTM B749 standard specifications. We typically ship sheet lead rolled and shrink wrapped to a pallet. After consulting the MSDS, these sheets of lead are easy to unroll, bend, cut, and shape without the need of special tools.

We offer sheet lead in a wide array of thickness to meet any needs. Pitts Little’s Lead Sheets are available in widths up to eight feet and lengths up to twenty five feet. Some typical thicknesses are:

  • 1/32” (2 lb/sq ft)
  • 1/16” (4 lb/sq ft)
  • 3/32” (6 lb/sq ft)
  • 1/8” (8 lb/ sq ft)

Our high quality sheet lead can be adhered to drywall, plywood sheathing or other substrates. Sheet lead is a very effective x-ray and gamma radiation shield. Other uses of sheet lead include waterproofing, soundproofing and vibration dampening.

Please contact us for a quotation on your sheet lead requirements. We will quote either the sheet lead in rolls or adhered to drywall, plywood or steel.

At Pitts Little Corporation, our premium Radiation Shielding lead lined wood doors are made-to-order according to your specifications. We take great pride in our quality and quick lead time. The door size, veneer type, and lead thickness are per your project requirements. We also fabricate lead lined hollow metal door frames. Pitts Little will provide options for your entire door mounting hardware, door operation hardware as well as any leaded glass and lead lined glass frames.


Pitts Little Lead Lined Doors are constructed with two solid core wood slabs, one on each side of a solid sheet of center core lead. Mechanical fasteners are installed on 8” on center. (Please click Submittal icon for illustration) All rails and stiles are hardwood. Typically, our custom made lead lined doors are available in birch and red oak, but we can apply any available veneer/skins to your door such as plastic laminate with edge strips.

Pitts Little lead lined doors are typically 1- ¾” thick with lead thickness ranging from 1/32” to 3/8” with the door thickness customarily increasing with lead over 1/8” thick. The lead thickness required for proper shielding must be determined by a licensed physicist. These doors are generally used in medical practices such as CT scan rooms, PET scan rooms and X-Ray rooms.


Pitts Little Radiation Shielding Lead Lined Door Frames are custom made to fit your lead lined door for seamless radiation shielding protection. Our Knock-Down (KD) and welded shielded drywall frames are made with 16 gauge cold-rolled steel engineered to have clean lines, rigid corners and fine miters on all joints. These frames typically have a 2” face, are double rabbeted, lined with lead per the customer’s specification and are primed ready for painting, but we can fabricate any design that meets your needs on a special order. Our frames can be used in drywall construction with steel studs, wood studs or laminate boards. Frame sizes match door sizes in any combination of single or pairs with a shielded leaf and a shielded astragal.


Pitts Little provides your entire Door Hardware needs for your lead lined radiation shielded doors. We have a variety of hinge options designed to shoulder the workload of the weight of a lead lined door. The most recommended choice is our Hager Roton Continuous Geared 780-224LL Lead Lined Concealed Leaf Hinge (pictured below). There is not a charge for door prep with this type piano hinge. We also offer Rixson Pivot hinges with a bottom, intermediate and top hinge prep. We can prep for other types of hinge hardware if required.

Lead lined plywood is typically utilized in applications requiring a lead thickness in excess of 1/8”. Any grade of plywood including fire-treated is available. Plywood panels are pressure laminated with a permanent adhesive to unpierced sheet lead and arranged to provide effective lead shielding through all joints. Depending on required lead thickness (determined by a health physicist), panels can be reduced in size to facilitate installation.


  • Place leaded side of plywood against studs.
  • Drill pilot holes 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.
  • Panels can be sized to match stud widths. This will require the installation of a batten strip along the seam.
  • The area between the batten strips can be filled with non-leaded plywood to facilitate the installation of the finished wall.
  • Install lead over or behind all penetrations, cuts, or punctures to ensure continuity of radiation shielding.

Gypsum drywall panels are pressure laminated with permanent adhesive to unpierced sheet lead and arranged to provide effective lead shielding through all joints. Gypsum board panels are secured to studs with drywall screws. Leaded drywall panels will be greater than or equal to the attenuation level specified by the physicist. Leaded dry wall sizes are typically on 5/8” thick or ½” thick 4’ x 8’, 4’x9’ or 4’x10’ sheetrock gypsum wallboard with 49” wide sheet lead rolled up to 7’ or 8’ high.

Some typical lead thicknesses are:

  • 1/32” (2 lb. per sq. ft.)
  • 1/16” (4 lb. per sq. ft.)
  • 3/32” (6 lb. per sq. ft.)
  • 1/8” (8 lb. per sq. ft.)

In addition to regular drywall, Pitts Little can apply lead to mold and moisture resistant gypsum wallboard, impact and abuse resistant gypsum wallboard and Type X fire rated wallboard. All drywall products are covered under the ASTM C 1396 gypsum board standard specification. Regular drywall is naturally fire resistant due to the presence of gypsum in the core, but it is not fire rated. Type X drywall includes special core additives that allow it to be used in fire rated designs and usually comes in 5/8” thickness. Pitts Little also can apply lead to plywood. Please see Lead Lined Plywood under Products.


  • Place leaded side of drywall against studs.
  • Drill pilot holes 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 lead lined drywall to studs with screws placed a maximum of eight inches on center.
  • Install sheet lead over or behind all penetrations, cuts, or punctures to ensure continuity of radiation shielding.
  • Please click on Submittal at the top right of this page for more information on installing lead lined drywall.

Drywall can be taped, floated and finished as required. Protect installed materials 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 one-inch lead overhang extends off one side of the 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 sheetrock. Batten strips are required at all drywall joints.

As for fastener, nail and steel screw penetrations, Pitts Little can provide lead discs, caps or plugs but they are not needed. Please see the section of the National Council on Radiation Protection and Measurements (NCPR) Report on the Submittal concerning these penetrations. If you do miss the stud while using screws to hang the sheetrock, for example, do not back the screw out. Just leave it inserted.
