Choosing the best windows for your home or business depends on your needs and budget. Vinyl and wood are popular window materials. There are also several window styles to choose from, such as double-hung, awning, casement, or fixed. The number of panes, how the windows operate, and how much ventilation they offer varies based on the chosen type of window. Other important features to consider when you are shopping for new or replacement windows include cladding, glazing, low-e coating, and tilt-in sashes.
