Nonprofit WindowDressers' insulating window inserts fit inside your windows to let in all the sunlight and views while keeping more heat inside your home. The inserts are high quality and low cost because they are built at barn-raising-style community workshops in Wiscasset and across Maine.

Once you sign up, trained volunteers will schedule a time to measure your windows for the custom-built inserts. Then, in the fall, you and other community volunteers will gather to build the inserts at one of 30 locations across the state. Special accommodations are made for participants with mobility challenges. The inserts are built of attractive pine frames and wrapped with a durable polyolefin film to create clear views through an insulating air space. Foam weather stripping around the outer edges stops drafts and aids the insert’s tight, custom fit. The inserts are installed from the inside of windows and held in place by friction. Depending on the efficiency of your windows and home, you could see fuel savings of up to 20 percent.

Pricing is based on size and finish, natural pine or white. A medium-sized 30 by 52 insert in pine costs $28 plus tax and in white costs $37 plus tax. WindowDressers offers low-income households up to 10 pine inserts free. Donations of any amount are always welcome.

In the Wiscasset area, WindowDressers’ volunteers are standing by to measure your windows now. The inserts will be built at the First Congregational Church, 28 High St, from Oct. 22 through Oct. 26.

The number of homes taken on by local workshops is limited to about 25, so interested households should sign up right away. Call Sam and Kayda Selby at (207) 837-0630 or email them at wdwiscasset@gmail.com. See a full list of locations at www.WindowDressers.org (207) 596-3073.
