Picture windows create a portrait-like space on walls – hence the word “picture” in their name. Picture windows are also a popular choice for letting in natural light without cold air in areas of a room that may be most susceptible to drafts.
In picture windows, insulated glass is a great option for added performance and increased comfort in the home. Insulated glass is a combination of two or more panes of glass with a hermetically sealed air space between them. Optional inert gases like argon or krypton may be used between panes to further improve thermal performance and energy savings.
