How They Work

Windows, Skylights & Exterior Doors

Windows, skylights and exterior doors are significant components of a home’s exterior envelope. Ensuring they are as energy efficient as possible can save energy; reduce heating, cooling and lighting costs; and improve home comfort. Replacing existing windows and skylights with new, efficient ones can cut monthly utility bills by as much as 15%. New exterior doors often fit and insulate better than older types.
