    
Gypsumboard: Our
standard system is based on 5/8" x 4' x 8' gypsumboard, ASTM C36 with long edges
tapered and round or beveled, Type X gypsum core with FS QQ-L-201f, grade C lead
of the required thickness bonded to the back face. Gypsumboard in 9' and
10' lengths and 1/2" thickness is also available, as is water board and Veneer
board.
Plywood / Paneling:
Depending on the requirements of the application, plywood or paneling in
interior or exterior, normal or fire retardant, and stain or paint grade is also
available. Our standard system is based on fire treated 3/4" plywood.
This application is most often utilized for lead thickness in excess of 1/8".
These thicker applications are seen primarily in PET/CT installations.
Windows
Frames:
We produce lead-lined Telescopic Window
Frames. These frames are manufactured from cold rolled 16 gage steel, with
welded seams and corners, ground and sanded smooth. The frame is then
primer coated and delivered to you with the specified lead lining, per your
specifications. With the telescopic design, these frames are perfect for
remodel applications, as well as new construction. Our standard frame is
suitable for finished wall thicknesses from 4.5 to 7". Removable stops and
mounting screws are provided with each frame.
Glass:
Radiation Protection Glass is available in sizes to a maximum of 4' x 8'.
This glass is high quality, optical grade materials, with a polished mirror
finish and contains not less than 60% heavy metal oxides, with at least 55% lead
oxide. Glass thickness is 5/16" and minimum lead equivalency is 1.58mm.
Doors
Species: We offer
many options for face and edge specie. Birch and Red Oak are standard.
Construction: All
doors are hand made within our own shop. We use 4" hardwood stiles and
rails for added strength and stability. Cores are high density industrial
grade particle board. All cores are glued and bolted. With the lead
sheet in the center of the door, there is no "face-heavy" tendency to swing only
one direction.
Lead
Sheet: We offer six standard
thicknesses, from 1/32" thru 1/8" consisting of a single thickness of FS
QQ-L-201, grade C lead. This certification standard insures the highest
level of lead purity (99.8) and is required by NCRP 147.
