Breathable^* Insulation

Airboard^® AERO dimensions are 4' x 8' [1.22m x 2.44m] with thicknesses from 5/8" to 6" [16-152mm] packed in bundles up to 12½" high. The graphite-enhanced, expanded polystyrene (GPS) insulation cores are laminated on both sides with perforated, 1 mil [25.4μm] metallic reflective facers made of biaxially oriented polypropylene (BOPP) and other polymers. GPS is closed cell foam insulation using air as main ingredient.

¹ The test methods used to determine the material properties provide a means of comparing different cellular plastic thermal insulations. They are intended for use in specifications, product evaluations and quality control but they are not intended to predict end-use product performance.  ² Values are for 1-1⁄16 inch or 25mm thick samples as indicated. Better values will result for thicker materials.  ³ R means resistance to heat flow. The higher the R-value, the greater the insulating power.  ⁴ Values are per testing with laminated facers intact & joints sealed, and for thicknesses as noted.   ⁵ The lab-test methods for water absorption use complete submersion under a head of water for 24 or 96 hours, so the values are applicable to specific design requirements only when the end-use conditions are similar to test method requirements. Unlaminated edges were sealed to reflect installation with sealed joints, penetrations & transitions.  ⁶ The elastic limit is between 1% and 2% strain. Compressive resistances at 10% strain are provided for applications where the intended end-use can tolerate plastic (permanent) deformation under load.  ⁷ not part of all the industry consensus standards (ASTM C578, CAN/ULC-S701.1) and provided AS-IS solely for informational purposes  ⁸ Minimum Density only applicable to USA-bound products per ASTM C578 (not Canada-bound products per CAN/ULC-S701.1).

UV-Light Degradation: Airboard^® AERO can be exposed to direct sunlight for a few weeks. Prolonged exposure to ultraviolet light can degrade the facers and GPS. Fading of the print on the facers does not affect performance.

Additional Properties of GPS

Graphite-enhanced expanded polystyrene (GPS) has no nutritional value for organisms and resists mold & fungi growth per ASTM C1338. To protect against animals place adequate physical barriers such as bug-screens or membranes around GPS.
Deformation due to Thermal Radiation: unprotected, gray GPS will deform when exposed to direct or reflected sunlight or other radiant heat sources. Keep GPS covered using opaque tarp, reflective covers or suitable indoor storage until finishes are installed.
Max. Service Temperature: Long-Term Exposure 74°C [165°F], Intermittent Exposure 79°C [175°F]
Thermal Expansion coefficient: 5-7•10^-5/°K per ASTM D696
Solubility: Insoluble in water and in general chemically inert. GPS dissolves in hydrocarbons (e.g. fuels, oils, tar), organic solvents (e.g. acetone/ketones, benzene, paint thinner), ethers, esters, aldehydes and amines. Capillarity: None
Surface Burning Characteristics Canada CAN/ULC-S102.2: Flame-Spread Rating ≤295, Smoke Developed Classification over 500.   USA Class A (NFPA 101), 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 GPS for construction applications contains a polymeric (non-HBCD) fire retardant modifier.
CAUTION: GPS 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

ª Ceiling measurement only, conducted through determination of flame spread index and smoke-developed index with the removal of any contribution of molten materials ignited on the floor of the Steiner tunnel.
