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
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
