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. Environmentally responsible, continuous insulation cores are sandwiched between pre-painted steel facings. Build attractive, sustainable, and budget-friendly facilities in record times by combining insulation, finishes, air, vapour & water-resistive barriers.
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.
The panels are 2-11" thick [50-280mm], 48" [1219mm] or 45-¾" [1162mm] wide and custom-cut to lengths per approved designs. The panels' facings are pre-painted, AZ50 aluminum-zinc coated or G90 galvanized steel in 26 or 24 gauge. They are bonded to the closed cell, expanded polystyrene (EPS) insulation core with a specially formulated adhesive.

Expanded Polystyrene (EPS) resists mold & fungi growth 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•
Dimensional Stability¹: max. 1.5% linear change per ASTM D2126 (7 Days @ 70±2°C)
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.
Surface Burning Characteristics Canada CAN/ULC-S102.2: Flame-Spread Rating ≤295, Smoke Developed Classification over 500. USA ASTM E84 (UL 723)ª: Flame Spread Index ≤25, Smoke-Developed Index ≤450 up to 6" thick
Limiting Oxygen Index: min. 24% per ASTM D2863. Airfoam's EPS for construction applications contains a polymeric (non-HBCD) fire retardant modifier.
CAUTION: EPS products are combustible and must not be exposed to excessive heat, sparks, open flames, or any other sources of ignition. A protective barrier or thermal barrier is required as specified in the appropriate building code. 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. GHS Classification: Non-Hazardous, see SDS
