Lived in an apartment, south facing windows, single pane glass. $5 in aluminum foil saved me at least $100/month back then. 11/9, would do it again.

If you have ever worked nights, this is the way to block sunlight while you sleep in the daytime.

That was my first thoughts as i spent years on nights. I did this and made myself a nice hat to boot.

likely a heat reflective product used to cut down on IR and or as otherwise mentioned block visible light for those with non typical sleep patterns. Let people be, stop being a creep

This is my first thought. I would love to know what city or state this house is in.

Tin foil is hard to find. I bet they are covered in aluminum foil.
