If your home has older windowssingle-pane windows that are drafty in the winter or windows with wooden frames, you may be thinking about buying storm windows. Storm windows fit into existing windows’ interior or exterior frames to provide an additional barrier against bad weather, wind and drafts. They can also increase the energy efficiency of your home while blocking out UV rays. And that’s not all. According to Ezra Laniado, founder of Landmark Construction Crew, storm windows also improve soundproofing. “If your property is near a loud site like an airport or sports arena, storm windows are an important investment that gives the occupants peace and quiet,” he says.

But not all storm windows are created equal. “The type you buy depends on your specific requirements, budget and aesthetic preferences,” says Jeramy Sibley, president of Glass Doctor. Read our larger storm window buying guide, which will help guide you through the process. Once you know what you need and your budget, these are our picks for the best storm windows in various categories.
