The Attachments Energy Rating Council (AERC) has certified six new secondary window systems for commercial use. The products include four interior storm window products from LARSON® Manufacturing, two interior and two exterior products from QUANTA, as well as two window insert products from Indow® Windows.
AERC ensures that window attachments are rated and certified to better meet the energy and comfortability needs of consumers. Secondary windows, in particular, offer an opportunity to address energy performance. For more on AERC and these commercial windows, visit aercenergyrating.org.
