Picture windows are fixed windows that don't open. They were generally introduced to project the beautiful surroundings and to let in the light. For unhindered perspectives where ventilation isn't a worry, picture windows are perfect. Picture windows create a canvas-like space in your home displaying the surroundings as portraits hence the word "picture" in their name. In picture windows, protected glass is a blend of at least two sheets of glass with a hermetically fixed air space between them. Discretionary dormant gases like argon or krypton might be utilized between sheets to additionally improve warmth and energy reserves.
