Insulated Metal Panels

Korolite® Insulated Metal Panels offer high performance building solutions that lower emissions, reduce lifetime costs and enhance indoor environmental quality. Energy-efficient and airtight insulated metal panels help create advanced building envelopes and cold-storage units using environmentally responsible, continuous insulation cores sandwiched between pre-painted, galvanized steel facings. Build attractive, sustainable, and budget-friendly facilities in record times by combining insulation, vapour barriers, weatherproofing and finishes.

Korolite® Insulated Metal Panels are highly versatile, available with various finished looks, and fast to install onto structural framing. Custom-manufactured to the specified lengths and thicknesses, the lightweight modular panels arrive at the jobsite ready to place. Unique interlocks help ensure continuous insulation and minimal air leakage with sealant applied between panels at the jobsite.

 

Applications

Curtain walls & partition walls for Warehouses, Cooler / Freezer Rooms, Commercial, Industrial, Agricultural, Cold-Storage Facilities, Refrigerated, Climate Controlled Buildings & more

Panel Interlocks

To help keep air leakage & thermal bridging minimal, our unique insulation finger joints and roll-formed steel edges help to ensure:
- airtight connections with continuous sealant applied between the steel recesses on both the interior and exterior sides and
- EPS overlaps between the panels. When only a butt end is used in competing products, small gaps can develop over time which result in thermal bridging and shadow lines.

Profiles & Colours

Usually the panel sides facing the interior are made with white smooth steel that's CFIA (Canadian Food Inspection Agency) approved and meets USDA requirements under part 16 (Sanitation).

For the other "exterior" side, you can chose between the same smooth steel (e.g. for coolers, freezers, partition walls), a soft beige stucco appearance finish, or standard, silkline or mesa profiles. Custom colors (light, not dark) are available for larger projects.

Wash-Down Finish

Fiberglass Reinforced Plastic (FRP) can be applied after installation of the panels to the building providing additional protection for applications with special wash down environments such as food processing areas. The FRP board can be applied to the whole length of the panels or select areas.

Doors

We can provide many types of doors for coolers, freezers, and production area applications, standard man doors, pallet doors and sliding doors. Options are available for stainless steel trim and aluminum kick plates. Freezer doors are available with 120 volt CSA approved heater wire, temperature gauge and ventilator port.


Technical Information

Korolite® Insulated Metal Panel Properties

The panels are 48" [1219mm] wide, 2-11" thick [50-280mm] and custom-cut to lengths per approved designs. The panels' facings are pre-painted, 26 or 24 gauge, G90 galvanized sheet steel bonded to the EPS core with a specially formulated adhesive. EPS is a closed cell, rigid foam that uses Air as main ingredient.

Additional Properties of EPS

Expanded polystyrene (EPS) resists mold & fungi per ASTM C1338 and has no nutritional value for insects. To protect against termites place adequate physical barriers such as membranes around below-grade EPS.
Max. service temperature: Long-Term Exposure 75°C [167°F]; Intermittent Exposure 80°C [176°F] Thermal expansion coefficient: 5-7 • 10-5/°K
Limiting Oxygen Index: min. 24% per ASTM D2863. Airfoam's EPS for construction applications contains a polymeric (non-HBCD) flame-retardant modifier.
Surface Burning Characteristics: CAN/ULC-S102: Flame Spread ≤290, Smoke Developed over 500.   USA ASTM E84ª: FSI ≤75, SDI ≤450
Solubility: Insoluble in water and in general chemically inert. EPS dissolves in hydrocarbons (e.g. fuels, oils, tar), organic solvents (e.g. acetone/ketones, benzene, paint thinner), ethers, esters, aldehydes and amines. Capillarity: None
UV-light surface degradation: white EPS can be exposed to direct sunlight for a few weeks. Prolonged exposure to ultraviolet light creates a yellow dust on the surface of EPS products, which has negligible impact on the products' properties but may require removal before adhering other materials such as stucco or self-adhesive membranes.
GHS Classification: Non-Hazardous, see SDS
CAUTION: EPS products are combustible and must not be exposed to excessive heat, sparks, open flames, or any other sources of ignition. If stored/used in closed containers, confined, or low-lying areas, ensure adequate ventilation to prevent accumulation of flammable pentane vapours. Prevent inhalation of smoke, fumes or dust from burning or fabrication activities. In addition, a protective barrier or thermal barrier is required to separate EPS products from interior living or conditioned spaces as specified in the appropriate building code.
