Window Screens

Window screens improve comfort. They let you open your windows to let fresh air into your home, while keeping pesky bugs and insects from entering. 

Window screens may be made of metal wire, fiberglass wire, or synthetic fiber mesh and are stretched in a frame of wood or metal and placed over a window opening. Their primary purpose is to prevent bugs, birds, other animals, and air-borne debris from entering your home, while permitting fresh air flow. Most houses the U.S. have screens on all exterior windows. Screens are especially important in areas that have large mosquito or other flying pest populations.

Most of us don’t pay much attention to our window screens until they fail to keep insects out of the house or they begin to look worn and tattered. It’s at this time that you may need to replace your window screens. Numerous types exist to complement the look and style of your home windows while keeping insects and dust out.

  • Fiberglass window screens. Fiberglass window screens come in fine, standard, and heavy-duty grades. Each grade has a different purpose. Fine fiberglass window screen is best to use if you need to keep out lots of small insects. This type of window screen is often used in marshy and coastal areas where gnats or sand flies may be a problem, especially during the summer months. Standard fiberglass screen is the most common and least expensive screen type and found in most homes in the U.S. It is generally used for windows in new houses and is long-lasting if the screens aren’t misused. Heavy-duty fiberglass screening is typically used in larger windows where the screen needs to be strong or needs to cover a larger window opening.  
  • Copper-bronze and aluminum window screens. Copper-bronze screening is made of 90 percent copper and 10 percent zinc, which makes it a very strong and durable window screen. Copper-bronze screens are considerably more expensive than aluminum screens but offer some substantial benefits to homeowners who reside in states with challenging weather conditions. However, aluminum screening is rust-resistant, non-sagging, and has a protective coating that withstands corrosion from coastal area weather, which often contains a high salt content. 
  • Pet screens. Pet screens are an ideal choice of window screen if you have pets that scratch at your screens or have young children, who can inadvertently be rough on screens. Pet screens are made of heavy-duty, vinyl-coated polyester, which is heavier and stronger than regular screening material. They also tolerate some stretching and pressure strains without sagging.
