I'm looking to find window fans that can extend up to 4 feet wide. I can't seem to locate any options out there and I'm curious why such fans aren't more common. Does anyone know if they exist?

Most window fans are designed for standard sizes, so they typically max out around 40 inches. If your window is wider, you might want to consider making some DIY adjustments, like using wood or foam board to fill in any gaps.

Yeah, foam board is a great option! You can easily cut it down without any heavy tools.
