Does NELCO lead-lined drywall pass LEED certification requirements?
Yes.
LEED™ NC Version 2.2, MR Credits 4.1 and 4.2: Recycled material content
• Indicate recycled content and provide manufacturer’s written certification of recycled steel and lead products
• Indicate percentage both post-consumer and pre-consumer recycled content per unit of drywall, plywood, and lead products.
LEED™ NC Version 2.2, MR Credit 5.1: Local/regional materials
•Indicate location of extraction, harvesting, and recovery; indicate the distance between extraction, harvesting, and recovery and the project site.
•Indicate location of manufacturing facility; indicate distance between manufacturing facility and the project site.
LEED™ NC Version 2.2, EQ Credit 4.1: Volatile Organic Compound (VOC) content

Can NELCO help determine appropriate drywall size and lead thickness?
Yes. Our physicists and experts will gladly assist in determining the best size, lead thickness, and wall layout to meet site requirements.
How are drywall pieces sealed together?
NELCO supplies 2″, 3″ or 4″ lead batten strips to shield the seams between each drywall piece, and typically either lead discs or lead tabs to protect the area where screws are attached. Lead discs cover the drywall screw heads, while lead tabs wrap behind the metal stud to protect the screw penetration.
Does NELCO shield penetrations such as electrical outlets, wall outlets, light switches, etc.?
Yes. To ensure an impenetrable shielding system, we also offer lead pieces (of equal thickness to the drywall) to line any penetrations, including electrical boxes, wall outlets, etc.
Can you add more than 1/8″ lead to drywall?
If more than 1/8″ lead is required, NELCO recommends you use our lead-lined plywood.
Is the drywall fireproof?
No, once lead is adhered to fire-resistant drywall, it loses its UL fire-resistance rating. However, NELCO does offer a full, fire-resistant drywall configuration (UL V439).

Homegeneous Lead Bonded Linings
NELCO’s lead burning experience and high level of quality is unsurpassed in the industry. Lead burning is also knows as lead welding and may be performed during the installation or maintenance of lead linings and coatings. The process involves using a lead burning bar which matches the same chemical compound of the lead being fused together. The material being joined along with the burning bar are heated with a torch the two are then melted and fused together.
• Tank Linings
• Vessel linings
• Lead Pipe
• Lead Storage Containers
• Lead Roofing
Lead Burning services may be provided on a scheduled or emergency basis.
All lead burning is conducted under our industry leading environmental, health and safety programs and guaranteed by our ISO 9001 accredited quality assurance program.
Lead Flashings
A lead roofing system isn’t complete without lead flashing from NELCO. Our experts install thin, continuous pieces of lead sheet to deter water surface tension and prevent it from seeping into a structure from a particular joint or angle. Our lead roof flashing is precisely positioned and secured around objects that protrude from the roof. The flashing dissipates the driving force of wind and water to deflect it away from each seam or joint. It works to waterproof protrusions such as pipes, supports, and cables. Lead flashing from NELCO ensures maximum water deflection for proper roof protection.
Lead Annodes
NELCO manufactures lead anodes in a large variety of shapes and sizes from plate, cast or extruded lead. In the event we don’t have the size or shape you need we can custom manufacture to any criteria.
In addition NELCO offers drilling, tapping, machining and assembly of the lead anodes. If required we can also fabricate and attach new header bars to the anodes.
All lead anodes are manufactured and assembled under the strict guidelines of our ISO 9001 accredited program.
