Common Questions

Answers Procurement and Operations Teams Ask Us First.

If your question isn’t here, send it on the form below — we reply within one business day.

What makes the MaxFab Tank Panel System different from traditional tank insulation?
Traditional tank insulation uses fibrous materials wrapped in horizontal bands. Over time, these absorb moisture, lose thermal performance, and cause corrosion under insulation (CUI). The MaxFab Tank Panel System uses the insulation core specified to your application — closed-cell polyisocyanurate, mineral wool, or fibreglass — laminated to pre-formed metal jacketing and sealed with a mechanically folded double-lock standing seam. No rivets, no screws, no penetrations. Designed for 25+ years of maintenance-free service.
Why choose a Canadian manufacturer over a U.S. supplier?
Every other standing-seam tank insulation manufacturer in North America is based in the United States. Choosing a Canadian manufacturer means no import duties, no cross-border freight delays, no currency exchange exposure, and a local team that understands Canadian operating conditions. MaxFab manufactures in Edmonton and delivers directly to industrial sites across Canada.
Does the tank need to be shut down during installation?
No. The MaxFab Tank Panel System installs without any welding to the tank shell. Panels are anchored using an internal cable-and-clip system, and seams are formed mechanically. The tank remains fully operational throughout the entire installation process. No hot-work permits are required.
What temperatures can the system handle?
The insulation core is specified to your application’s operating temperature. Across the material options, the system serves cryogenic applications from approximately −196 °C (closed-cell PIR) up to high-temperature process applications around +650 °C (high-temperature mineral wool). Specific temperature ratings depend on the core material chosen for your project.
What insulation materials does MaxFab use?
Three core options are available depending on application: closed-cell polyisocyanurate (PIR) for cold and cryogenic service; rigid mineral wool board for hot and high-temperature process service; and fibreglass when specified by the client. The right core is selected for each project based on operating temperature and performance requirements.
How long does installation take?
Significantly less time than traditional methods. Because panels are pre-fabricated in our Edmonton facility to exact tank dimensions, the majority of labour happens indoors before the panels reach your site. On-site installation is designed for a small crew working from a boom lift — no scaffolding setup or teardown. MaxFab can coordinate experienced installation contractors on your behalf.
What’s the expected lifespan of the panel system?
25+ years, maintenance-free. The double-lock standing seam maintains its weather-tight seal through decades of thermal cycling and weather exposure, and the closed-cell or non-absorbent material options do not degrade through moisture absorption.
What tank shapes and sizes can MaxFab insulate?
The MaxFab Tank Panel System is custom-designed for each project. Cone roof tanks, dome roof tanks, and cylindrical tanks of all diameters. Every panel is fabricated to match your tank’s exact dimensions, including accommodations for nozzles, manways, stairs, and other protrusions. MaxFab has insulated tanks up to 132 ft diameter by 145 ft high.
How does the MaxFab Tank Panel System prevent corrosion under insulation (CUI)?
Two mechanisms work together. First, the double-lock standing seam creates a sealed exterior envelope with no rivets, screws, or penetrations where water could enter. Second, the moisture barrier (Surlyn by DuPont) heat-laminated to the interior of the aluminum jacketing prevents moisture contact with the jacket interior. The combination is designed to prevent the conditions that cause CUI.
Does MaxFab handle the full project or just supply panels?
MaxFab designs and manufactures the panels in our Edmonton facility — including the CNC plasma cutting, metal forming, lamination, and double-lock seaming. We also coordinate experienced installation contractors on your behalf. From scope to fabricated panels to installation coordination — one point of contact for the project.
Tank Insulation Glossary

Quick reference for the language used on this page.

CUI — Corrosion Under Insulation
Localized corrosion of metal beneath thermal insulation, most aggressive on carbon steel between −12 °C and 175 °C. Caused by moisture trapped against the jacket interior. The MaxFab sealed-envelope double-lock seam is designed to prevent the conditions that allow CUI to develop.
Double-Lock Standing Seam
A mechanical metal-to-metal joint formed by folding adjacent panel edges twice. Weather-tight without rivets, screws, sealants, or penetrations. The same seam technology used in architectural metal roofing.
Polyisocyanurate (PIR)
A closed-cell rigid foam insulation. Industry-typical operating range roughly −196 °C to +150 °C. Does not absorb moisture, so its K-value remains stable for decades. Used in MaxFab Tank Panel System panels for cryogenic and cold-service applications including LNG.
Mineral Wool
A non-combustible fibrous insulation made from molten rock or slag spun into fibres. High-temperature service to approximately +650 °C for industrial board products. Used in MaxFab Tank Panel System panels for hot and high-temperature process service.
K-value (Thermal Conductivity)
A material’s ability to conduct heat. Lower is better for insulation. PIR is around 0.022–0.027 W/(m·K); mineral wool varies by density and temperature. K-value is the foundation of all heat-loss calculations.
Jacketing
The outer metal skin of an insulated tank. The MaxFab Tank Panel System uses ASTM B209 wrought aluminum (alloys 1100, 3003, 3105-H14) in 0.016″ to 0.032″ thicknesses, with a Surlyn moisture barrier heat-laminated to the interior.
NFPA-22
The U.S. National Fire Protection Association standard for water tanks for private fire protection. Tanks under NFPA-22 require thermal protection that the MaxFab Tank Panel System supports.
Cone Roof Tank
A storage tank with a low-pitch conical top. Common in oil and gas storage. MaxFab Tank Panel System panels are custom-cut to match the cone radius, dome, or pie-segment geometry of the roof.
