What This Tool Is

The Only IMP Estimator Built by the Installer.

Direct answer: Insulated metal panels (IMP) cost $12 to $35 per square foot installed in 2026 depending on thickness, manufacturer, profile, and finish. Cooler walls run $14–$24/SF, freezer walls $18–$30/SF, blast freezer $24–$35/SF, ceiling panels $14–$28/SF, architectural wall panels $12–$25/SF, and cleanroom/pharma panels $22–$35/SF. The TCG estimator returns Good/Better/Best supply + install pricing in under 60 seconds, calibrated against real installation data from over one million square feet of IMP delivered across all 50 states by self-performing crews.

Most online IMP "calculators" are produced by manufacturers selling panels — they price the panel and forget the labor, freight, joints, sealants, doors, and integration scope that's two-thirds of the real installed cost. Our estimator is built by the installer. The pricing reflects what TCG actually charges, not what a panel costs FOB factory.

Cost Benchmarks

How does the IMP cost estimator work?
Upload your architectural plans (PDF or image) or describe your project in plain English. Our AI reads dimensions, calculates panel square footage by zone (cooler, freezer, ceiling, architectural), and returns a Good/Better/Best installed cost estimate in under 60 seconds. The estimate reflects supply plus installation pricing, calibrated against TCG's real installation data from over one million square feet delivered across all 50 states.
How much do insulated metal panels cost installed in 2026?
Installed IMP costs in 2026 range from $12 to $35/SF depending on thickness, manufacturer, profile, and finish. Cooler walls (4-inch panels, R-32) run $14–$24/SF, freezer walls (5–6-inch, R-40 to R-48) run $18–$30/SF, blast freezer run $24–$35/SF, ceiling panels run $14–$28/SF, architectural wall panels run $12–$25/SF, and cleanroom/pharma panels run $22–$35/SF. See the IMP installation labor cost guide for category-by-category breakdowns.
What is the difference between Good, Better, and Best?
Good = standard polyurethane core, factory finish, fit-for-purpose for most cooler and warehouse envelopes. Better = higher R-value cores, upgraded finishes, enhanced air-tightness gaskets, tighter joint tolerances. Best = premium panels with FM-approved assemblies, stainless steel or FRP facings, FDA/USDA/cGMP compliance, certified third-party-tested fire performance — required for pharma, cleanroom, and high-spec cold storage.
How thick should panels be for cold storage?
Coolers (34–38°F): 4-inch panels at R-32. Freezers (0°F to -10°F): 5–6-inch panels at R-40 to R-48. Blast freezers (below -20°F): 6-inch+ panels or double-panel assemblies at R-48+. Cleanrooms typically use 4-inch panels driven by hygiene and fire rating, not thermal performance. See our cold storage IMP guide for the full panel-thickness-by-temperature-zone matrix.
What IMP manufacturers does TCG work with?
TCG has direct procurement and installation relationships with Kingspan, Metl-Span (Cornerstone), CENTRIA, AWIP, PermaTherm, FALK, UPI Panels, MBCI, Arch Solar, and ATAS International. For a side-by-side comparison see Best IMP Manufacturers in the USA (2026).
What types of buildings use IMPs?
Cold storage, food processing, pharmaceutical cleanrooms, cannabis, data centers, breweries, climate-controlled storage, and CEA.
Does TCG self-perform IMP installation nationwide?
Yes — TCG self-performs IMP installation across all 50 states with in-house crews. Self-performance gives owners single-source accountability on cost, quality, schedule, and warranty without subcontractor markup or coordination gaps.
Do I need completed construction documents to use the estimator?
No — the estimator works at any drawing stage. A schematic floor plan with overall dimensions, an elevation showing panel heights, or even a hand-marked sketch with the major panel zones can produce a meaningful budgetary estimate. The more detail you provide, the tighter the range.
What is the lead time on insulated metal panels in 2026?
As of May 2026, IMP lead times run 8–14 weeks from PO release for most manufacturers. Stocked profiles ship in 6–8 weeks. Custom thickness, custom color, and FM-approved or USDA-rated assemblies can stretch to 14–18 weeks. Section 232 steel tariffs continue to flow through panel pricing at 5–12% of installed cost. For broader supply context see our 2026 material lead times guide.
How long does IMP installation take?
A 10,000 SF cold room: 5–10 days. A 50,000 SF facility with multiple temperature zones: 4–8 weeks. A 200,000 SF distribution-scale envelope: 12–20 weeks. TCG crews install 800–1,500 SF per day per crew, depending on panel size, joint detail, fire rating, and access.
Can TCG handle both supply and installation?
Yes — turnkey supply + install: direct manufacturer procurement, freight, on-site layout, panel cutting, installation, trim/flashing, sealant, and door/window integration. Single-source accountability on warranty and joint detail.
Is the AI estimate accurate enough to budget against?
Yes for budgetary purposes — typically within ±10% of the final TCG-verified proposal on cold storage envelopes where panel zones are clearly indicated. Final pricing depends on access, schedule, fire rating, accessory packages, and site conditions. We always recommend confirming the AI estimate with a TCG estimator before committing to a budget.
Are uploaded plans stored or shared?
Uploaded plans are processed securely and not shared with manufacturers, third parties, or other clients. TCG retains files only as long as needed to verify the estimate and prepare a follow-up proposal. If you require a signed NDA before submitting plans, contact us at info@terrapincg.com and we will execute one before you upload.
