Replacing an Old Window with a New High Efficiency Window

While replacing an old window with a brand new high efficiency model, Larry Janesky from Dr. Energy Saver demonstrates how to install a replacement window for the best energy efficiency, and explains what a window energy efficiency label means. A window is always the coldest spot in a wall and can feel leaky from heat transfers and the “convective loop.” High efficiency replacement windows — if installed properly ­– can help your home feel less drafty, save on energy costs, and look great. Understanding the labels and energy efficiency ratings will help you shop and save money with replacement windows.
