New Law Temporarily Lowers R-Values for Duct Insulation to R-4.2

Governor Roy Cooper signed this legislation yesterday, March 17, 2022

This new law temporarily changes the Commercial and Residential insulation R-value for ducts installed in ventilated and nonventilated non-conditioned spaces (crawlspaces and attics). 

Based on this legislation, contractors can install ducts in Residential ventilated and non-ventilated unconditioned spaces (crawlspaces and attics) with a minimum of R-4.2 insulation. This law will allow for reduced duct insulations values for a period of two years and is now in effect.

• Any changes in duct insulation values must be included in your load calculation
• If you are questioned by an inspection department in reference to the duct R-values, please refer them to House Bill 243
