Damper PerformanceTesting Criteria®Thermal PerformanceDuring thermal performance test, per ASTM Standard C1363-97conducted at Architectural Testing Laboratories (ATI), the ICD-45outperformed competitor’s thermally broken dampers.(Report #53166.01-201-46)Dry Ice TestThe thermal breaks in the damper blades and frame reduce thetransfer of heat from the “cool side” to the “warm side”. Whencompared to a standard airfoil blade design, ICD airfoil blade,with thermal breaks, prevents ice from forming on the oppositeside of the blade.Specimen Thermal Resistance (R value)GreenheckICD-45Brand ABrand BLeakage TestICD series dampers meet the IECC (International Energy Conservation Code) requirements for damperleakage ratings of at 3 cfm/ft 2 @ 1 in. wg (54.8 cmh/m 2 @ .25 kPa) or less when integral to the buildingenvelope. Leakage testing was performed at Environ Laboratories at a temperature of -40°F. The ICD-45 wasrated at less than 3 cfm/ft 2 @ 1 in. wg (54.8 cmh/m 2 @ .25 kPa) or 8 cfm/ft 2 @ 4 in. wg (146.3 cmh/m 2 @ 1 kPa).Comparing a 36 in. x 36 in. (914mm x 914mm) damper, Greenheck’s ICD series has the lowest leakage in theindustry.GreenheckBrand ABrand B5
