The more windows you install at one time, the less you'll pay per window. Talk with your contractor to determine which type suits your climate.

Vinyl, wood, and fiberglass are much better insulators than aluminum.Īny frame material type or design can include high-efficiency glass and Low-E coatings. Low-E coatings add 10%–15% to the cost but reduce infrared heat in the summer, lowering your air conditioning bill. Windows account for 25%–30% of your home's heat loss. Replacing windows for better thermal insulation with Energy Star-rated varieties helps you save on your utility bills and may help you qualify for local or federal energy rebates. “Consider using these windows on areas of your house that are not protected by roof overhangs, the topography of your site, or trees.' This is because the units have a strong seal on all four sides when closed, which keeps air out,” says Cati O’Keefe, Expert Home Building & Sustainability Contributor. 'Casement windows are the most energy-efficient style you can buy (aside from fixed windows). You will have a higher initial investment, but you will save on energy costs in the long run, depending on your climate. Usually, the higher the price, the more energy-efficient the windows are. Thermally-insulated, energy-efficient windows run anywhere from $120 to $1,200 or more. This style attempts to capture the best of both worlds by mixing PVC polymers with wood fiber to create a strong, attractive frame. CompositeĬomposite windows cost between $300 and $1,100. Though aluminum is still available, it's far less popular than other types since it's tough to paint, doesn't insulate well, and typically costs more than vinyl or composite. Aluminum or MetalĪluminum can range anywhere from $400 to $1,200 or more for large or high-end varieties. This material is more durable than vinyl with similar insulation properties. Fiberglassįiberglass units cost an average of $750 each, including installation. That's why some historical neighborhoods have covenants requiring wood framing. The work and money can be worth it for wood's classic, authentic, and architectural appeal. If you fail to repaint and finish wood units, they become susceptible to the elements. Wood frames cost $1,300 on average and require regular maintenance. Their greatest drawback is that they're not as sturdy or attractive as wood. Most manufacturers stand behind their products with strong warranties, sometimes even lifetime warranties. They're also extremely durable changes in humidity don't cause them to swell or shrink. Vinyl windows cost $250 to $600 and require little maintenance.
