IMC Code Change Update

The 2009 code change that required 28 gauge residential sheet metal ducts has been reversed in the 2015 International Mechanical Code (IMC). The code change proposal submitted by ACCA, modified by SMACNA and supported in floor debate by representatives of Ductmate Industries and M&M Manufacturing Company was approved in the IMC Final Action Hearings.

Many states have struggled with how, and even whether or not, to enforce the change that first appeared in the 2009 Mechanical Code and International Residential Code (IRC). “The code change hearings for the IRC will be in May of 2013 and we are optimistic of getting the 28 gauge requirement removed from that code as well. What we’ve learned is that we have to be vigilant and engaged in the code adoption process in order to protect the interests of the HVAC industry”, said Chris Van Rite, VP Sales, M&M Manufacturing Company.
