Insulation and Windows


The Consumers Energy Insulation and Windows (INWIN) Program is designed to improve the energy performance and durability of existing residential housing in Consumers Energy service territories. The program offers financial incentives to participating homeowners for the installation of qualifying insulation and windows measures in eligible single- and multifamily dwellings (fewer than four units).

The objective of the program is to increase the demand for energy-efficient improvements for insulation and windows to produce long-term electric and natural gas energy savings to Consumers Energy residential customers. The rebates help offset the cost difference between choosing a standard product and an energy-efficient one.
