Window Assessment

Point out any problem windows during your initial energy consult and look at samples of our custom-built window inserts. Energy savings rarely justifies the cost and disruption of full window replacement, so choose these inserts to cost-effectively eliminate drafts, reduce heat loss, improve comfort, reduce outside noise, and prevent condensation on window glass.

Choose Your Window Insert

Window Cozys have 1"x2" wooden frames with crystal-clear polyolefin film, foam weatherstrip edging, and small tabs for easy removal. They can be customized to your specifications:

Custom Window Inserts | Evergreen Home Performance | MaineDouble- or triple-glazed: Window Cozys get their insulating value from the air trapped between layers of polyolefin film. Adding another layer of film - and air - increases the R-value of your window insert for even greater protection against heat loss.

Unfinished or finished wood: Your Window Cozys are available with unfinished pine framing, painted white, or in a custom color or wood to match your decor.

Non-standard windows: Since each Window Cozy is handmade in Camden, Maine, we can easily accommodate custom shapes and large sizes. Window Cozys are even available for skylights.

Durable Window Cozys allow you to preserve the historic character of your original windows while upgrading comfort and performance. Even better, Window Cozys deliver the energy savings of a standard double pane window at a fraction of the cost, and their installation is easy and construction-free.
