I want to silence the sound of rain drops falling on my window air conditioners by putting some kind of pad on top of them. (The sound is keeping me awake.) I also need to be very frugal right now so I'm looking into using what I have around the house. I have a roll of polyester fiberfill that I've used for quilting and crafts. It is thermally bonded spun polyester fibers. (I got this idea from someone else who said they used an air filter pad, which I think can be either spun polyester or spun fiberglass.)
I've seen a couple of "drip pads" for this purpose for sale online. But, for a couple of reasons, they won't work for me.
In considering how to make these pads, I've had a few questions for which I can't find answers on the internet. Maybe someone one on this site has the answers.
1)I had to place one AC in the direct afternoon sunlight - no choice. I know the metal housing must get very hot with the summer sun beating down on it. Does anyone know how hot the metal housing on the AC would get in, let's say, 100 F weather with the sun directly on it?
2) Does anyone know the melting or burning point (F) for spun polyester?
3) Does anyone have any opinion about a low cost material that would work better than spun polyester? (It would need to be breathable, not hold water, not break down quickly in the sun, and certainly not burn or melt and run into the AC unit.)
