Use this form to sign up for interior window inserts to reduce your home's heat loss. The insert program is coordinated by Sustainable Hanover, the Norwich Energy Committee, and the Thetford Enregy Committee in collaboration with the WindowDressers non-profit organization https://windowdressers.org/. The insert prices are exceptionally low through a non-profit model of cooperative insert-building, with customers contributing time at a "Community Build" workshop -- like a barn-raising.
