DOORS & FRAMES

Lead-Lined Wood Doors

Lead-lined wood doors are available in particle core or Laminated Strand Lumber (LSL) core construction with hardwood edges to match face veneers. Standard construction is called CoreClad^® and has lead located under each door skin. Nominal door thickness is 1-3/4". CoreClad^® construction is available up to 3/8" lead thickness. Above that thickness up to 1/2" lead thickness, center lead is the design commonly used.

Fire labels are available for lead lined wood door ratings of 20 minutes, 45 minutes, and 60 minutes in both Positive Pressure and Neutral Pressure versions, up to and including 1/4" lead. Single leafs up to 4'0" x 8'0" and pairs to 8'0" x 8'0" are included with listed lites up to 1,296 square inches at 20-minute fire ratings and up to 100 square inches for 45- and 60-minute fire ratings.

A & L recommends door weight be reviewed with the hinge and door frame manufacturers as well as the installer prior to final hardware selection.

Door weights usually require either pivot type or continuous hinges especially designed for use with lead-lined doors.

Shipment

Each wood door is custom-designed and often can be manufactured and shipped within ten working days. Special veneers may require additional time.

Lead-Lined Hollow Metal Doors

Lead-Lined Hollow Metal Door Frames

Door frames must be lined with lead equal to the wall shielding level. All hardware preparations are shielded to guard against leakage. Hardware and preparations must be coordinated to match the higher than normal door weight.

Welded type frames for new construction and knock-down versions for use in existing walls are available. Wall thickness including lead lining must be specified when the frame is ordered.

Lead linings are welded together in the frame to prevent movement during shipment and installation. Fire labels are available as are special gages of metal and internal angle bracing if this is required by the door weight and the architect’s design.

Bullet Resistant Doors and Frames

Bullet resistant doors contain a laminated fiberglass core covered by wood and finish veneer. Matching hardwood edges allow the door to appear similar in design to a conventional wood door. UL protective levels 1, 2, 3, and 6 are offered at present.

Hollow metal door frames with bullet resistant material installed inside are a companion product that normally is purchased with the bullet resistant door. All testing of doors for bullet resistance includes frame testing. A system purchase of door and frame is recommended by A & L Shielding Inc.
