Replacing the drafty single-pane basement windows with glass block was a wise decision, adding warmth, privacy, and improving overall energy efficiency. Glass block windows are highly insulating, creating a barrier against cold air and moisture. They also diffuse natural light, creating a soft and inviting atmosphere in the basement. Virtually maintenance-free, these windows require only occasional cleaning. This upgrade not only enhanced the basement's comfort and livability but also increased the value and appeal of the entire home.
