A nonprofit that rates the energy performance of window attachments such as shades, blinds and shutters, helping compare how products affect heat flow.
The Attachments Energy Rating Council is a nonprofit that develops ratings for window attachments, which include cellular shades, roller shades, shutters, blinds and similar products. Its work aims to give a consistent way to compare how an attachment changes heat flow through a window. Homeowners in Nashville who care about comfort and energy can use this kind of information to compare products.
Ratings are useful guides, and the fit of a treatment in your window matters too. A product with a good rating can still leave gaps if it is mounted poorly. We talk about ratings when they are available and explain how mounting, edge gaps and daily use affect real results.
