How to prevent aluminum window frames from heating up when they’re in full sun

insulationwindows

There is a room that has a window, the frame of the window is made of aluminum. This window is subjected to direct sunlight a long time of the day, which makes the aluminum get really hot, and start acting as a heat radiator and heating up the room pretty quickly.

What can I do to block the sun from heating up the window frame?

I tried putting some paper with adhesive tape, but it was not durable at all, even though there wasn't a lot of rain or water.

I prefer something DIY, if possible.

Some ideas to try:

  1. Paint the window frames white. This will reflect the light instead of absorbing it. This might make quite a difference by itself
  2. Cover the frames with XPS foam. On the inside you'd need to cover the foam with drywall or another fire barrier.
  3. Plant a tree or bush near the window to help shade it
  4. Replace the window with a vinyl window. It's not as hard as it sounds and can definitely be DIY
  5. Install an awning or trellis above the window (Thanks DA01)
