Why Some Neighbors Are Putting Aluminum Foil in Their Windows

If you've recently driven through your neighborhood and noticed shiny sheets of aluminum foil pressed against windows, you might be wondering what's going on. Is it some kind of strange security measure? A signal for help? Or maybe an unconventional warning of something more sinister? The sight can be unsettling, sparking wild theories about what's happening behind those reflective barriers. But while it might look ominous, the real reason is far more practical—and surprisingly clever.

Is It Safe?

While aluminum foil is generally safe to use for short periods, experts suggest not keeping it on windows permanently. Prolonged use can trap heat between the glass and foil, which could potentially cause damage to window seals. It's best used as a temporary measure or removed during cooler seasons.
