The Basics

What Is an Insulated Metal Panel (IMP)?

An Insulated Metal Panel (IMP) is a factory-made sandwich panel: two steel faces bonded to a rigid foam core (PIR, PUR, EPS or mineral wool). One panel is the wall or ceiling, the insulation and the finished surface.

R-30

Thermal Performance

A 4" (100 mm) panel delivers R-30 (RSI 5.3), well above the R-10 to R-19 typical of metal stud and drywall construction.

1 Panel

Wall, Insulation & Finish

Framing, insulation, vapor barrier, drywall and paint become one installed panel.

Fast

Installs in Days

A typical crew installs 1,000–1,500 sq ft (93–139 m²) a day, and 5,000 sq ft (465 m²) in 4–5 days.

Insulated Metal Panels (IMP) are used for cold storage and cold rooms, cultivation and grow rooms, cleanrooms, food processing, data centers, warehouses, aircraft hangars and pre-engineered metal buildings. See every industry.

Sustainability

Built to Last. Built to Be Recycled.

Sourcing

Material & Sourcing

Panels manufactured with recycled steel content and responsibly sourced raw materials, with the embodied carbon of the panels themselves factored into every product decision we make.

Efficiency

Performance & Efficiency

High R-value insulation and airtight seams cut building energy use for the life of the structure, while panel durability stretches replacement cycles far beyond conventional cladding.

Circular

End-of-Life & Circularity

A long useful life on the building itself, steel cores that are fully recyclable at the end of that life, and take-back options that keep panels out of the landfill.

Flooring

Floors to Match Your Room.

Epoxy coatings, grind and seal finishes, and combined material and install packages.

Flooring

Epoxy Flooring

Seamless, chemical- and abrasion-resistant epoxy floor coatings built to hold up under heavy foot and equipment traffic in industrial and commercial spaces.

Trim and Accessories in a Typical Room

  • Floor Connection. Option A: 20 ga (0.91 mm) galvanized U-track, web sized to the panel thickness. Option B: two white HS aluminum L angles, 1.2 mm (16 ga), in 6 m (19′-8.22") lengths, one on each side of the panel. Either one is anchored to the slab and sealed with butyl; the project engineer sets the anchor spacing.
  • Screws. One screw type throughout: 1/4" × 1/4" × 7/8" (6.35 × 22 mm) Tek.
  • Inside Corner Trim. 2" × 2" × 26 ga (51 × 51 × 0.46 mm), continuous, on the room side.
  • Outside Corner Trim. Continuous 26 ga, on the warm side, over sealant.
  • Flat Batten. 26 ga, 4" (102 mm) wide minimum, over a ceiling-to-ceiling butt joint above a partition.
  • Joint Covers and Z-Flashing. Where thickness changes or the drawings call for them.
  • Ceiling Support. 3/8" (9.5 mm) galvanized all-thread hanger rods with hidden ceiling clips and carriage bolts, SL-01 aluminum ceiling tees on long spans, and unistrut across the bottom chords of roof trusses.
  • Butyl and Sealant. Under the track, at corners and joints, and on the warm side to keep the vapor seal continuous.

FAQ

Frequently Asked Questions.

Can’t find an answer? Email Sales@harvestpanels.com.

What Are Insulated Metal Panels (IMP)?
Insulated Metal Panels (IMP) are factory-made sandwich panels with two steel faces bonded to a rigid foam core (PIR, PUR, EPS or mineral wool). They combine the wall or ceiling, the insulation and the finished surface in one panel, so rooms and buildings go up faster than with framing and drywall.
What Are Insulated Metal Panels (IMP) Used For?
Cold storage and cold rooms, walk-in coolers and freezers, cultivation and grow rooms, cleanrooms and laboratories, food and beverage processing, data centers, warehouses, aircraft hangars, workshops, modular buildings and pre-engineered metal buildings. See our industries page for details.
Can Insulated Metal Panels (IMP) Be Used for Cold Rooms and Walk-In Coolers?
Yes. Cold storage is one of the most common uses. Our 4" (100 mm) panel delivers R-30 (RSI 5.3), and we offer hygienic cold storage panels, hinged and sliding cooler doors, and the trim and sealants to finish a cold room. Tell us the temperature you need and our team will recommend the right panel.
Do You Offer Panels for Grow Rooms and Cultivation Facilities?
Yes. Insulated Metal Panels (IMP) help hold steady temperature and humidity for grow rooms, cultivation facilities and indoor farms, and the moisture-resistant steel and PVC faces wipe clean. Tell us the size of your room and we will price the panels.
Can Insulated Metal Panels (IMP) Be Used for Hangars and Warehouses?
Yes. Insulated wall and roof panels are used on aircraft hangars, warehouses, distribution centers and pre-engineered metal buildings. Send us your spans, loads and local code requirements and we will recommend a wall or roof panel. Final engineering is by the project engineer.

Panels typically range from $4 to $8 per square foot, depending on length and thickness. We also offer a Best Price Guarantee, matching a competitor's written quote. Contact us with your specs for an accurate, free estimate.
What Sizes Do Panels Come in?
Panel thickness ranges from 2" to 8" (51–203 mm; 4" / 100 mm is our standard), lengths run 10' to 36' (3.0–11 m; stock lengths of 10', 12', 14', 16', and 20'), and widths are 39.37" (1,000 mm) or 45" (1,143 mm). We can also manufacture custom sizes to fit your exact project dimensions.
Do You Offer Installation Services?
Yes, we offer full installation services in addition to supply-only orders.
How Long Does It Take to Install Panels?
Installation can cut an estimated 60-80% off traditional construction time. A typical crew installs 1,000-1,500 sq ft (93-139 m²) a day, 5,000 sq ft (465 m²) in 4-5 days, and 10,000 sq ft (929 m²) in 7-10 days.
Insulation Value?
A 4" (100 mm) panel delivers an R-30 (RSI 5.3) insulation value, well above the R-10 to R-19 typical of metal stud and drywall construction. Exact values vary by thickness and core material, our team can recommend the right spec for your climate and use case.
Can Panels Support Hanging of Equipment?
Yes, with the appropriate panel type and mounting hardware, panels can support hanging equipment and fixtures.
