How to Order Custom Lead Glass (Step-by-Step)
Ordering custom lead glass isn’t complicated—but it does require accurate technical information. Missing or incorrect details can lead to delays, re-fabrication, or non-compliant shielding.
This guide walks you through exactly what information you need, common mistakes to avoid, and realistic timeline expectations so your project stays on track.

Step 1: Gather Required Project Information
Before placing an order, you will need the following key specifications:
- Lead equivalency (mm Pb): Typically determined by a shielding report
- Glass dimensions: Exact width and height of each opening
- Quantity: Number of panels required
- Application type: X-ray, CT, fluoroscopy, dental, etc.
- Safety glazing requirement: Laminated or tempered where required
- Frame type: Lead-lined or compatible shielding frame system
- Installation environment: Control room, wall partition, viewing window, etc.
The most important input is typically the shielding report prepared by a qualified medical physicist, based on NCRP guidelines.
Step 2: Confirm Shielding Requirements
All lead glass specifications must align with your radiation shielding design, typically based on:
- NCRP Report No. 147 – Structural shielding design for medical X-ray imaging facilities
- ASTM C1036 – Standard specification for flat glass
- ASTM C1172 – Laminated architectural flat glass (safety applications)
This ensures the glass meets both radiation protection and building code requirements.
Step 3: Select Glass Type and Configuration
Depending on your project, you may need to choose:
- Standard lead glass – Basic shielding applications
- Safety lead glass – Laminated or tempered for impact resistance
- High-equivalency glass – For CT or high-output systems
Safety-rated options are often required in occupied areas and healthcare environments where impact resistance is a code requirement.
Step 4: Review Frame Compatibility
Lead glass must be installed in a system that maintains continuous radiation shielding.
Common frame requirements include:
- Lead-lined or shielded frames
- Proper load-bearing support for heavy panels
- Flush integration with surrounding wall shielding
Frame incompatibility is one of the most common causes of failed installations.
Step 5: Place Order with Accurate Specs
Once all specifications are confirmed, the order is submitted for fabrication. At this stage, accuracy is critical—custom lead glass is manufactured to exact dimensions and cannot typically be modified after production.
Common Mistakes When Ordering Lead Glass
- Missing shielding report inputs: Guessing lead equivalency instead of using physicist data
- Incorrect measurements: Not accounting for frame tolerances
- Ignoring safety glazing requirements: Leading to code compliance issues
- Ordering before final design approval: Resulting in redesign and reorders
- Frame mismatch: Glass not compatible with installed system
These mistakes often result in delays, increased costs, and inspection failures.
Timeline Expectations
Lead times vary depending on complexity, but typical timelines are:
| Order Type | Estimated Lead Time |
|---|---|
| Standard lead glass | 2–4 weeks |
| Safety laminated lead glass | 3–6 weeks |
| Custom oversized panels | 4–8+ weeks |
Additional time may be required for international shipping, specialty fabrication, or high-volume orders.
Final Thoughts
Ordering custom lead glass is straightforward when the correct information is provided upfront. The key to avoiding delays and costly mistakes is working from a validated shielding report and ensuring all specifications align with code requirements.
By following a structured ordering process, you can ensure your lead glass is fabricated correctly the first time and integrates seamlessly into your shielding system.
Frequently Asked Questions (FAQs)
What information do I need to order lead glass?
You need lead equivalency (mm Pb), exact dimensions, application type, safety requirements, and shielding specifications.
Can I order lead glass without a shielding report?
It is not recommended. A shielding report ensures the correct lead equivalency and compliance with NCRP guidelines.
How long does custom lead glass take to manufacture?
Typically 2–8 weeks depending on size, complexity, and safety requirements.
What causes delays in lead glass orders?
Incorrect specifications, missing documentation, and design changes after ordering are the most common causes.
Is safety lead glass required for all projects?
Not all, but many healthcare and commercial applications require laminated safety glass under ASTM C1172 guidelines.
Can lead glass be resized after ordering?
No. Lead glass is custom fabricated and cannot be cut or modified after production.
