How to Find the Cause of Drafty Windows

POSTED ON in Global Blogs

Find the cause of drafty windowsThere is a point every winter when you can’t locate the source of the draft in your home. It could possibly be coming from a window that isn’t closed or sealed correctly, or it could result from another source. Even the smallest of cracks can make homes uncomfortable and chilly, resulting in larger heating and cooling costs.

According to the Environmental Protection Agency’s ENERGY STAR® program, you can save 10 percent on your monthly energy bill, or 20 percent of your heating and cooling costs, with appropriately sealed windows. To help limit spending and decrease drafty air from passing through your home, it’s important to be able to identify where these drafts could be originating from and why. Here are some helpful tips to find your home’s drafts and check for issues:

  1. Look for gaps and cracks in unusual points of air leakage, such as knee walls, outdoor faucets, attic doors or windows with workable means and use a straightforward visual inspection.
  2. Inspect to ensure that windows and doors are shut and latched.
  3. Make sure that the sealant or gasket around the operable portion of the window or door is properly sealing.
  4. Test the installation by verifying if the draft is passing through the window or around the window, between the window and the coarse opening. A window will only perform as well as it is installed.
  5. Call a specialist from Pella Windows and Doors to have them conduct a home energy audit.

Once you’ve found where the draft or air leakage is originating, the next step is to concentrate on the foundation of the draft or air leakage.
