Energy Efficiency

• 1). Determine how much energy efficiency you need. Windows with good energy efficiency can lower your fuel bills in the summer and winter. Determine your Energy Star climate zone and evaluate options that will improve your energy efficiency.
  
  
• 2). Determine whether you need double- or triple-pane glass. More panes equal more energy efficiency and greater sound reduction.
  
  
• 3). Consider Low-E glass. It reflects infrared light, keeping heat out in the summer and in during the winter. It also blocks ultraviolet rays, helping to protect furnishings and carpets from fading.
  
  
• 4). Consider adding a gas between the glass panes, such as argon or krypton, which provide better insulation than regular air.
  
  

Window Design

• 1). Evaluate the various styles of windows to determine which make sense for you from both a design and a practicality perspective. Consider the way that the windows open, and whether you want the ability to tilt your windows inward for washing.
  
  
• 2). Consider casement windows that have hinges on the side or awning windows with a hinge on top. Both have crank handles for opening and closing. With single-hung windows, the bottom pane slides up while the top pane remains stationary. With double-hung windows, both panes move.
  
  Gliding windows work by sliding one pane horizontally over another, while picture windows do not open.
  
  
• 3). Evaluate grill patterns. Windows with no grill offer unimpeded views. Grill patterns that slice the window horizontally or vertically add height or width. Grill patterns can divide the window into multiple squares or rectangles as patterns, complementing your home's architecture.
  
  
• 4). Determine whether you want screens over your windows. Screens add practicality if you like to open your windows in mild weather, but they can obscure your view.
  
  

Visit Window Retailers

• 1). Use the Yellow Pages or Internet to find window retailers in your area.
  
  
• 2). Handle the vinyl windows you are considering. Open and close them, understand how the locks work and test them.
  
  
• 3). If you are considering double-hung windows, make sure you can operate both panes easily.
  
  
• 4). Examine frame colors to best match your décor. Consider frames that are one material on the inside, such as wood, and vinyl on the outside.
  
  

Financial Benefits

• 1). Check with your energy provider to determine if it offers incentives for purchasing Energy Star-rated products.
  
  
• 2). Request written price quotes from each manufacturer whose windows interest you. Take the quotes home and compare prices and features, including the cost of installation.
  
  
• 3). Check with your tax provider to determine if your vinyl window purchase qualifies for a federal or state tax energy-efficiency improvement credit.
  
  
• 4). Compare the cost of Energy Star-qualified vinyl windows with other windows. Energy Star-qualified products may cost more, but factor in the benefit of tax credits and energy savings before making a final purchasing decision.
