Insulated Metal Panel

Insulated metal panels combine two metal sheets with an insulated core to provide thermal resistance, structural protection, and finished surfaces in a single assembly. These prefabricated building components streamline construction for commercial, industrial, and residential roofs and walls by eliminating multiple material layers and reducing installation time compared to traditional built-up systems.

The panels typically feature steel substrates with weather-resistant coatings and rigid foam insulation cores. Polyisocyanurate (PIR) foam delivers R-values around 7 to 7.2 per inch, while advanced technologies like QuadCore achieve up to 8.0 per inch. The foam core enhances acoustic performance and airtightness while maintaining lightweight properties at approximately 3.3 pounds per square foot.

Available in corrugated, trapezoidal, and flat profiles, panels range from 24 to 45¼ inches wide and 1 to 8 inches thick, providing R-values from R-5 to R-72. Standard lengths extend up to 54 feet, accommodating pitched roofs with slopes as low as 4 degrees, flat roofs, wall systems, and specialized applications like cold storage facilities.

Installation utilizes concealed or exposed fasteners attached to structural trusses with support spacing of 4 to 5 feet. Interlocking joints ensure secure placement, while the prefabricated design enables rapid assembly and supports additional installations such as solar panel mounting systems.

Aluminum Foam Core Panel

Lightweight sandwich panel with two aluminum skins laminated to a foam core for thermal insulation and reduced dead load. Offered in multiple foam options and thickness ranges, it suits façades, partitions, roofing, and cold-room envelopes where insulation and easy fabrication matter most.

Aluminum Honeycomb Panel

High-stiffness aluminum sandwich panel using an aluminum honeycomb core for superior rigidity at low weight. Compared with foam-core types, it prioritizes flatness, strength, and impact resistance, making it ideal for large-format cladding, transportation interiors, and applications demanding high strength-to-weight.

Aluminum PET Sandwich Panel

Aluminum-skinned panel with a PET foam core, balancing insulation, dimensional stability, and mechanical strength. Versus PU or XPS, PET typically targets a more structural feel and better temperature tolerance, making it a solid choice for façades and partitions needing strength without heavy weight.

Aluminum PU Sandwich Panel

Aluminum sandwich panel with a PU foam core focused on maximum thermal insulation and energy efficiency. Compared with PET or PVC foam versions, it is often chosen when insulation performance is the top priority, such as cold storage, insulated enclosures, and climate-controlled building envelopes.

Aluminum PVC Sandwich Panel

Aluminum composite sandwich panel with a PVC foam core, valued for processing friendliness and stable performance. Compared with PU, it emphasizes balanced insulation and workability; compared with XPS, it often targets robust panel feel for interior partitions, signage, and architectural cladding systems.

Aluminum XPS Sandwich Panel

Aluminum-faced panel with an XPS foam core designed for strong insulation and moisture resistance. Compared with PU, it commonly targets a cost-effective insulation build; compared with PET, it leans more toward insulation over structure, fitting roofs, wall cladding, and refrigerated-room linings.

Stainless Steel Sandwich Panel

Composite panel with stainless steel face sheets bonded to lightweight foam or honeycomb core. Delivers superior corrosion resistance, high strength-to-weight ratio, excellent flatness, thermal insulation, and fire resistance for architectural facades, commercial kitchens, and industrial applications.

Insulated Metal Panel (IMP) & Warehouse Envelope Guide

Insulated metal sandwich panels (IMPs) represent the single-source solution for high-bay logistics warehouses, distribution centers, industrial manufacturing plants, and commercial building envelopes. Factory-assembled with high-R polyisocyanurate (PIR) foam ($\lambda pprox 0.020$ W/m·K) encapsulated between pre-painted steel facings, IMPs integrate continuous air, water, vapor, and thermal control barriers into a single modular installation step.

💡 Pro Tip: Rapid Building “Dry-In” & ASHRAE 90.1 Compliance
At RaxPanel, our industrial warehouse panels achieve continuous thermal insulation tested under ASTM C518 (R-7.2 to R-8.0 per inch). Installing large-format IMPs slashes weather-tight building dry-in schedules by up to 50% compared to tilt-up concrete or multi-component cavity walls.

1. Why Are IMPs Preferred Over Tilt-Up Concrete and Built-Up Cavity Walls?

Concrete tilt-up panels are heavy, thermally conductive, and require long curing times. RaxPanel IMPs provide superior thermal resistance per millimeter of thickness, lightweight structural purlin attachment, and immediate weather-tight building enclosure.

2. What Thermal and Air Infiltration Standards Define Industrial IMPs?

Engineered to comply with stringent ASHRAE 90.1 and IECC energy conservation building codes:

Performance Standard	RaxPanel Technical Metric	Warehouse Operational Advantage
ASTM C518 Thermal R-Value	R-7.2 to R-8.0 per inch (PIR Core)	Reduces warehouse HVAC heating/cooling energy costs by 30%+
ASTM E283 Air Leakage	Air Infiltration ≤ 0.01 cfm/ft² at 75 Pa	Prevents uncontrolled air drafts and humidity condensation traps
ASTM E331 Water Infiltration	No Dynamic Water Leakage at 720 Pa (15 psf)	Protects valuable inventory against driving storm moisture
EN 13501-1 / FM 4880 Class 1	Class B-s1,d0 / FM Approved Core	Lowers commercial building property insurance premiums

3. Seamless Integration of Air, Vapor, and Water Control Barriers

Traditional walls require separate vapor retarders, air barrier wraps, and insulation batts. IMPs unify all four building envelope control layers into a single continuous panel assembly.

4. Concealed Fasteners & Architectural Wall Micro-Rib Profiles

🏭 Industrial Architectural Aesthetics:

Concealed Fixing Clips: Screws anchor the male tongue flange prior to interlocking the adjacent female panel seam, hiding fasteners.
Micro-Rib & Embossed Finishes: Micro-ribbing adds flexural rigidity to panel skins while eliminating surface oil-canning.

5. Where Are Insulated Metal Panels Most Commonly Installed?

📦 E-Commerce Fulfillment & Logistics Hubs

Large-scale high-bay warehouses requiring rapid dry-in timelines and low operational energy costs.

⚙️ Manufacturing Plants & Industrial Enclosures

Durable exterior wall cladding and roof envelopes resisting industrial pollutants.

6. On-Site Crane Lifting and Fast Vacuum Rig Installation

IMPs are lifted using vacuum suction cup rigs, allowing a small installation crew to erect over 500 to 1,000 square meters of wall facade per day.

Frequently Asked Questions (FAQS)

1. What is an Insulated Metal Panel (IMP) and how does it function?

An IMP is a factory-engineered sandwich panel featuring an insulating foam core (PIR/PUR) bonded between two structural metal skins, integrating air, water, vapor, and thermal barriers.

2. What thermal R-value per inch do RaxPanel IMPs achieve?

RaxPanel PIR core IMPs deliver approximately R-7.2 to R-8.0 per inch of core thickness when tested according to ASTM C518 standards.

3. How do IMPs reduce warehouse construction schedules?

Single-step panel erection eliminates separate insulation batts, building wraps, and drywall, achieving building dry-in up to 50% faster.

4. Are RaxPanel warehouse IMPs FM Approved for fire safety?

Yes. Our PIR core formulations meet FM 4880 Class 1 fire resistance standards and EN 13501-1 Class B-s1,d0 requirements.

5. What panel thicknesses are specified for industrial warehouse walls?

Standard wall thicknesses are 50mm, 75mm, 100mm, and 120mm depending on local energy conservation code requirements (ASHRAE 90.1).

6. How are panel joints sealed against air and water leakage?

Joints incorporate interlocking tongue-and-groove profiles with factory-applied non-skinning butyl sealants, passing ASTM E283 air and ASTM E331 water tests.

7. What maximum panel lengths can be produced for high-bay warehouse walls?

Panel lengths up to 11.8 meters are standard for containerized transport, allowing full-height single-panel wall spans without horizontal intermediate joints.
