Awning Window Replacement

What Are Awning Windows?

Awning windows swing open from the bottom, which means they are hinged at the top. They typically open outward which allows ventilation while preventing leaves and rain inside. Most often awning windows are used in basements.

Benefits Of Awning  Windows

Awning windows are excellent when paired with non-operable windows like picture windows. When not used in basements, awning windows are placed above or below the non-operable windows to add airflow capability because they’re smaller than casements or double hung windows. There are a lot of different types of windows, so it’s important to know the benefits of the window style that you’re interested in.

Awning Windows Pros

  • Ease Of Use – A rotating handle makes it easy to open in basements since they’re usually high on the wall, and easy to use when above or below a non-operable window
  • Able To Add Ventilation – Picture windows don’t allow for ventilation, so awning windows are often added above & below to add airflow
  • Save On EnergyEnergy efficient design
  • Versatile Look – The flat exterior frame is convenient for lap siding or brick construction
  • Low-maintenance – The vinyl never needs painting
  • Safety – They are more difficult to crawl through
