Put tin foil on your windows to reflect heat

[dustyrhodes]

If you put the aluminum foil on the outside, it’s even more efficient. The glass won’t be heated. You would need to tape it down though.

I use my foil for my tin foil hat top keep gamma rays away and the voices out.😊

[westlundberg]

I was about to use tape to keep the foil on my window. I never would have thought of applying it using plain old water. Easy Peasy! Thank you for sharing this. You my dear, are awesome! 😊

Use it with cardboard box. It will increase the R-value and insulate your house better.

Wipe your window with a sponge(water+soap), clean it off, spray windex on window or tin foil, apply it!
Simple, mine have been up for about 2 years now🤷‍♂️

it is because actually uv light is a radiation which bring the heat, while aluminium foil block uv light then no heat is transfered

I have 5 long windows just in our living room and about to put foil, shiny side facing outside bc this Texas heat is ridiculous.

Im literally doing this to my whole house right now

[josemilian]

temps for before and after would be cool

[Ourlifenanana]

Does it matter which side of the aluminum foil is facing in

And ur neighbors will assume ur cooking meth

Mylar (space blanket) is far more effective. You can tell how good a material is by placing an ice cube and the material in your hand. If it feels cold, its a bad insulator.

It works until you wanna take them off after a while, the window will be coated with white substance presumably some oxides created with the presence of water and sunlight.

[cherrymay]

you can easily use foil blanket and just tape it

All fun and games until it catches on fire

[jmnsugna]

It won't stay. The moisture evaporates and it begins to fall off.

[kyerawilliams]

What did she use to make it stick? Just water?

[mattdumas]

That's not a hack, that's the way to get the window cracked on a sunny day.

[mydarlingfinds]

Use liquid starch instead of water and put the aluminum on the outside.
