About Illinois’ Insulation Requirements

Illinois established its most recent insulation requirements in 2019. The minimum commercial roof insulation requirements for installation above the roof deck are R-30ci for all climate zones.

The R-value measures heat flow resistance and insulation power. The higher the R-value, the greater the insulation power. These requirements apply to both new construction and roof replacements.

Roof Alterations and Compliance

Any roof alteration must abide by these regulations. The insulation requirements allow for cost-saving and energy-efficient roofing solutions. When installing above the roof deck, roofers must use insulation products with thermal resistance above R-30ci to ensure proper insulation.

High heat resistance on the roof membrane also ensures commercial buildings follow energy conservation codes and helps protect the roofing system from environmental wear and tear.

The purpose of the Illinois commercial roof insulation requirements is primarily to protect business owners and customers from faulty construction. These building codes apply to various types of roofs, including
