Ruskindampers and louvers meet the International Energy Conservation Code's (I.E.C.C.) recently adopted new criteria concerning damper leakage and the measurement of outside air intake. According to the I.E.C.C. 2003, paragraph 802.3.4: Dampers integral to the building envelope shall be equipped with motorized dampers with a maximum leakage rate of 3 cfm/sq ft at 1 in./ w.g. Ruskin meets this requirement with the Model CD50 and CD60. Both dampers carry the AMCA certified label for both Air Performance and Air Leakage.
