No Fibers. No Tin. No Sealants. A Better Way to Insulate Industrial Piping
For decades, industrial insulation has relied on the same approach: fiberglass or mineral wool wrapped in thin metal jacketing, taped and sealed in the field. It’s a multi-layer system with inherent weaknesses: moisture intrusion, UV degradation, mechanical damage, and installation variability.
This traditional approach may be familiar, but it’s outdated, not just in materials, but in its ability to meet modern industrial demands. In harsh environments where thousands of feet of pipe, fittings, and equipment are exposed to weather, vibration, and ongoing maintenance, legacy fiberglass and tin systems simply don’t hold up.
Dragon Jacket Insulation was engineered to replace that system. No fibers, no tin, no sealants. Each insulation section is a single-piece, prefabricated, moisture-impermeable component, custom-fit for long-term performance with virtually no on-site fabrication and dramatically reduced failure points.
Out With the Old: Why Legacy Materials Fail
Fiberglass and mineral wool are effective insulation materials in interior, controlled environments, such as within the walls of residential or commercial buildings. They can conform to tight spaces and remain undisturbed for years. However, their soft, porous, and highly absorbent nature makes them poorly suited for exterior industrial applications.
Once exposed to moisture from rain, condensation, or washdowns, these materials lose thermal performance, compress under their own weight, and accelerate corrosion under insulation (CUI). The thin metal jacketing intended to protect them dents and tears easily, and once breached, traps moisture against the pipe.
In industrial settings, installation is also slow and labor-intensive. Every tank, valve, elbow, pipe, and fitting must be measured, cut, wrapped, taped, sealed, and jacketed by hand. Each step introduces potential failure points, and most insulation failures trace back to seams, joints, and field-fabricated details that fail to keep water out.
In other words, the weaknesses are baked into the design.
A New Approach: A Monolithic, Moisture-Proof System
Dragon Jacket takes a fundamentally different approach. Rather than layering multiple materials with multiple failure modes, it uses a single engineered system: a rigid, closed-cell insulation core fully encapsulated in a polyurea shell.
-
No fibers.
-
No jacketing.
-
No sealants.
-
No paths for water intrusion.
Each section is custom-manufactured using 3D measurement and produced as a single-piece clamshell precisely matched to the geometry of the pipe or fitting. From Victaulic® couplings and valves to bridge-mounted mains and expansion joints, every piece is designed to fit the application exactly.
This monolithic construction blocks moisture from every angle and maintains structural integrity long after traditional systems fail.
Fully Encapsulated, Completely Waterproof
The key to Dragon Jacket’s effectiveness lies in its outer shell. The polyurea exterior is:
-
100% moisture-impermeable
-
UV-resistant
-
Impact-resistant
-
Chemically inert
-
Stable across extreme heat and subzero temperatures
Unlike metal jacketing, the shell does not dent, corrode, or degrade over time. It is designed to keep water out over decades of service, preventing the condensation and moisture intrusion that lead to corrosion under insulation (CUI). And because the insulation core is closed-cell, it cannot absorb water even if the outer shell is pierced, gouged, cut, or scraped during maintenance. The result is stable R-value, intact insulation, and long-term protection of the equipment underneath.
No Field Fabrication, Ever
Traditional insulation systems rely on installers to fabricate insulation for complex shapes in the field. Dragon Jacket eliminates that requirement.
Each component arrives prefabricated to fit the exact geometry of the pipe or fitting being insulated. Installation requires no cutting, taping, or sealing. Sections are simply clamshelled around the component and secured with steel bands or other approved fasteners. No mess, no specialty trades, and no weather-dependent fabrication.
Because each piece is rigid and durable, it can be removed for inspection and reinstalled without compromising performance — a capability that fiber and tin systems cannot provide.
A System Built for Real-World Industrial Conditions
Dragon Jacket’s fiberglass-free, tin-free design eliminates the issues industrial teams know too well: CUI, moisture, UV degradation, deformation, and repeated insulation replacement. Engineered for 20+ years of service in harsh environments, Dragon Jacket transforms insulation from an operating expense into a capital asset.
If your insulation system still relies on fiber, tin, and sealants, you’re fighting a losing battle against water, weather, and wear. Dragon Jacket offers a smarter, longer-lasting solution that installs faster and protects infrastructure as it should.
