Introduction:
Cold air leaking through poorly sealed PVC windows is a problem in many homes—even with new windows. The good news is that adjusting the windows only takes a few minutes and doesn’t require any special tools. Here’s a simple way to easily eliminate drafts.
How can you tell if heat is escaping?

When you run your hand over the window frame, you might feel a cool sensation, suggesting a slight creaking sound.
You can also test this with a lit lighter: if the flame flickers or goes out near the frame, it needs to be adjusted to the window.
