Permits unvented attics and unvented enclosed rafter assemblies to be sealed with air-impermeable insulation to help achieve building decarbonization.

New York S05940 amends the executive law to allow unvented attics and unvented enclosed rafter assemblies to be sealed with air-impermeable insulation, aiding in building decarbonization goals. This change supports the state's clean energy and climate agenda by improving energy efficiency and reducing greenhouse gas emissions. The insulation must meet specific criteria, including a blower door test result and the installation of a balanced mechanical ventilation system.
