Lead Lined Drywall
Lead-lined drywall, or lead-lined sheetrock, consists of gypsum board laminated with sheet lead to provide shielding from high-level gamma-ray and X-ray radiation. Lead-lined sheetrock is integral in medical, scientific, and industrial applications that use high dose radiation for diagnostic imaging and procedures. Commercial builders also use lead-lined drywall for applications requiring abuse resistance, impact resistance, and mold or moisture resistance.
Advantages of installing gypsum board with lead lining include:
- Provides effective floor-to-ceiling radiation protection
- Offers design flexibility for use in walls, floors, and ceilings
- Eliminates the risk of radiation leakage when properly installed
- Available in varying thicknesses to meet a wide range of shielding requirements
Achieve High-Level Radiation Shielding with Lead-Lined Sheetrock
Lead-lined drywall is a permanent radiation shielding solution that offers more effective protection than semi-permanent or mobile partitions. Having the right protection is especially important for treatment rooms and other applications where employees are at risk of prolonged radiation exposure.

Lead-Lined Drywall Manufactured to Meet Your Shielding Requirements
Radiation Protection Products offer a wide variety of lead-lined drywall sizes to meet your shielding application requirements. We offer quick pricing on standard requests and can do a take-off of your blueprints to provide a detailed project quote.
All our lead-lined gypsum board consists of a single unpierced sheet of lead laminated to the specified thickness of the drywall. The lead sheeting is bonded to the gypsum board with a continuous layer of mastic adhesive. Our commitment to quality includes:
- Using only Fire Code Sheetrock in our lead-lined drywall products
- Casting and rolling lead lining in-house using only the purest lead available
- Applying industrial-grade adhesive to keep lead sheeting securely adhered
Lead lined gypsum board comes in 1/2" or 5/8" drywall thicknesses, with custom sizes available. Select from lead lining in thicknesses up to 1/8” with optional double layering for high radiation applications. We provide 2" lead strips of the same thickness and height of your lead sheeting for sealing vertical joints for installation.

FAQs for Radiation Shielding with Lead Lined Sheetrock
We’ve answered a few of the most common radiation shielding questions below. You can also see more FAQ's here. Please read our Lead Shielding Considerations for additional tips or give us a call to discuss your project.
How do I determine how much shielding I need?
Our guide on Radiation Shielding Requirements can get you started, but we recommend working with a licensed radiation health physicist to determine your required lead thickness.
What are the sizes and specifications for lead-lined drywall?
Do I need to worry about covering penetrations?
3/8” lead discs are no longer required to cover fastener penetrations; however, you still need to properly shield light switches, air ducts, and other receptacles. Learn more about cut-out and penetration shielding requirements.
Lead Lined Drywall Installation Requirements
To fully support the lead’s weight, we recommend using 5/8” gypsum board for your lead wall installation. If your radiation shielding application requires lead sheeting exceeding 1/8” you will likely require lead-lined plywood to properly support the weight of your lead wall.
Proper installation of lead-lined drywall is critical to prevent radiation leakage. All lead-lined gypsum board should be installed with the joints running vertically from floor to ceiling to meet industry standards.
- Fasten your lead-lined drywall at a minimum of 8" on center at the edges of each sheet, and at a minimum of 12" on center at the intermediate studs with standard drywall screws.
- Apply 2" wide strips of sheet lead of the same lead thickness to each of the joint studs using a standard type of construction adhesive. These strips of sheet lead will provide the necessary 1" overlap with the adjoining sheets.
