Intech’s Bestselling Shielding Products — Why They’re Industry Favorites

From hospitals to heavy-industrial labs, shielding products need to deliver reliable protection—but they also must adapt to the space, workflow, and longevity demands of the people who use them every day. That’s why Intech’s top sellers aren’t just effective; they’re thoughtfully engineered for real-world conditions. Let’s explore four of the most popular Intech solutions, how they’re constructed, and the highlights that make each a go-to choice.

🧵 Lead-Free Soft Shielding (Curtains & Drapes)

Intech’s lead-free curtains and flexible drapes continue to be top picks in hospitals, NDT facilities, dental and vet practices. These products are not merely fabric—they are engineered shielding systems using high-performance composites.

• What they include: Lead-free composite panels (typically tungsten, bismuth or antimony based) encapsulated in durable vinyl or nylon shell. Available in common equivalencies such as 0.25 mm, 0.5 mm and 1.0 mm Pb.
• Highlights:
  • Flexibility for access: These curtains roll, slide or swing—ideal for doorways, open bays or mobile imaging zones.
  • Non-toxic advantage: Since they contain no lead, they sidestep hazardous waste disposal and simplify logistics.
  • Cost-efficient for scatter control: Where shielding is required for scatter (not direct beam), they offer a strong value.

🔩 Lead Plate

When you need maximum density in a compact form, lead plate is still a core offering in shielding design. Intech supplies lead plate in sheets, cut-to-size panels, and custom configurations.

• What it is: Sheets of pure lead (density ~11.34 g/cm³) manufactured in common thicknesses (1/32″, 1/16″, up to several inches), used where heavy shielding is required.
• Highlights:
  • Superior attenuation: For high-energy photons or tight spaces, lead plate offers the most efficient shielding per thickness.
  • Custom shaping: Easily cut, weld or bolt for complex installations, irregular layouts or retrofits.
  • Longevity: Once installed correctly, lead plate serves for decades with minimal maintenance.

🧱 Lead Bricks (Including Interlocking Bricks for “Caves”)

Lead bricks remain a workhorse solution for labs, isotope enclosures, testing bays and more. Intech’s interlocking brick systems are especially popular for building modular “cave-style” shielding walls.

• What they are: Machined lead blocks available in standard and interlocking profiles. Tongue-and-groove locking bricks create tight joints that minimize leak paths.
• Highlights:
  • Modularity: The interlocking design enables easy stacking, reconfiguration, and reuse—ideal when layouts or workflows change.
  • Mainstream application: While they serve many roles, building “brick caves” around hot sources is the primary use—making this the reason bricks remain so "hot".
  • Heavy-duty protection: Excellent for shielding heavy isotopes, containerized sources or test enclosures where portability of shielding is less critical.

🏗️ Fortress™ Adhesive Wall Panels (Lead-Free)

For facilities aiming for modern, streamlined installations with minimal disruption, Intech’s Fortress™ adhesive wall panels offer a lead-free alternative. These panels use tungsten-based composite shielding laminated to a fire-resistant sheet with pressure-sensitive adhesive backing.

• What they are: Lead-free shielding panels available in equivalencies from 1/32″ (0.8 mm Pb) to 1/8″ (3.2 mm Pb), in sizes like 2′×4′ and 1′×2′, with options for interlocking edges.
• Highlights:
  • Minimal construction: Peel-and-stick installation over existing walls—no demolition, mudding or painting required.
  • Lead-free benefits: Eliminates lead hazards, simplifies disposal and supports sustainability initiatives.
  • Versatile sizing & finishes: Panel sizes and shapes tailored to fit clinical or lab environments with minimal seams and cleaner aesthetics.

Why These Offerings Lead the Market

Across these four categories, certain design and performance themes recur. Facilities choose them because they deliver:

• High performance shielding: Whether lead-free or traditional lead, each product is rated for appropriate mm Pb equivalency and designed to meet or exceed code requirements.
• Adaptability: From flexible curtains to permanent brick walls, the product line supports fixed rooms, mobile cells, and evolving workflows.
• Long-term value: Products designed to last decades, with reuse-friendly modular systems (bricks), lighter environmental burden (lead-free), and trusted materials (plate).
• Ease of installation or reconfiguration: Panels that stick, modular bricks that stack, curtains that roll—all reduce downtime and labor.

Key Takeaways

• Lead-free curtains offer flexible, non-toxic shielding for scatter zones and mobile areas.
• Lead plate remains the go-to for the densest, most compact shielding needs.
• Lead bricks—especially interlocking types—provide modular, reusable shielding walls and caves when flexibility is key.
• Fortress™ adhesive lead-free wall panels bring modern installation ease and sustainability to wall shielding.
