Why do people put foil over their windows?

Question

My old neighbors had a window covered and my current do as well. Foil covering the entire inside of the window.

Answer 1

To block out the sunlight. It's probably a day sleeper in that room. In Alaska during the long summer days it's common to see windows blocked with tin-foil. The sun sets at 1:am and rises at 2:30 am. It's a pain sometimes.

Answer 2

Usually to keep the light out..Or people from looking in to see whats happening. I have read it can change the t emper of the glass and it will break easier. Because it reflects the UV and heat back.

if it is just 1 or 2 windows it is usually to keep the sun out it reflects the sun and keeps it cooler in the room. If it is all the windows then probably hiding illegal activity.
