Window attachments are products which can be attached to a window either internally or externally to improve energy performance, create a more comfortable environment, reduce glare, provide privacy and enhance the appearance and value of your home.
Why use Energy-efficient Window Attachments?
Energy-efficient window attachments are important for both new and existing homes. About 30% of a home’s heating energy is lost through windows. In cooling seasons, about 76% of sunlight that falls on standard double-pane windows enters to become heat. Window coverings can help with this loss of energy by providing comfort, regulating temperatures, and lowering energy bills. The exact savings will depend on the type of attachment, the season, the climate, and how the attachment is used. In addition to the window coverings, storm windows with low-e coatings and/or multi-layer glazing are effective at improving thermal performance of windows and reducing solar heat gain.
