The Illinois Home Weatherization Assistance Program (IHWAP) is designed to help low income residents save fuel and money, while increasing the comfort of their homes. Its mission is to insulate the dwellings of low-income persons, particularly the elderly, persons with disabilities, families with children, high residential energy users, and households with a high energy burden, in order to conserve needed energy and to aid those persons least able to afford higher utility costs.
