Yeah its a baby

Shiny side towards the sun

I still use them every summer.

😉 yay!

wait.. what? how does that happen?

I've done this with double pane windows and hadn't noticed a problem, but I didn't do it to cover the whole window, so I don't know. I'm guessing what happens is the aluminum is reflecting back the 95% or so of radiant heat and it heats up the inner area between the panes so much that it becomes under pressure?

Me! It’s till 90 in Olympia and I’m dying

@@jacqueofallgames I’m in Lakewood and it was 99! This helped a lot with cooling off our back bedroom which gets all of the late afternoon sun. Stay safe!

Seattle & dying! 🥴 Gonna try this tomorrow even tho it’s supposed to cool down.

this summer is gonna be hotter , humidity at over 80% 2 days ago .

🤣🤣🤣🤣

Give us an update on your results please

Because the shininess literally reflects the heat away. The heat just bounces off. You can also have the shiny side facing inside, then the heat inside will bounce back in, and not escape out the glass window (which is handy for winter).

Aluminum reflects about 95% of radiant / infrared heat (think like sunrays). So the shinier it is (like a mirror) the better it reflects that kind of heat. Funnily enough, a lot of mirrors are great at reflecting light (visible light), but not great at reflecting infrared / radiant heat ( which is not visible to human eye). Aluminum is a good conductor of heat (often used for computer heatsinks). This means ambient heat or heat from another object can transfer through aluminum very easily. So basically Aluminum is great at stopping radiant heat and sucks at stopping conductive heat. Which brings me to why I'm on this video looking around. I'm trying to see where someone is talking about the improvement gained by using the cardboard backing, but I think I'm looking for something a bit nerdy/scientific, as I'm thinking the cardboard should help to stop the conductive heat transfer into the room right at the window, some. Something of a recap: you're using the aluminum for it's reflective properties against radiated infra red heat, and using the poorer conductive properties of cardboard to stop or slow the conductive heat passing through the solids of the glass and into the house.

Awesome!

@@DarkDarkPrincess it really does, I be in my house shaking like a crackhead it be so cold and I live in Las Vegas nevada😂😂😂😂

@@onesicinfi did you dp the hole house or just the bedrooms? Do you still recommend this 1 yr later? My electricity rates are going up so I am trying tin foil for now

Yep 106 on sunday 😡😠

JUST BOUGHT REFLECTIX FROM LOWE'S AND MY TEMPERATURE DROP 15 DEGREES IT'S ICE COLD IN HERE NOW. LOL THANK YOU

@@dmon3331 115 degrees on Thursday here in Phoenix Arizona

Did it work?

Reyna Rubio ....IKEA sells black out blinds for 6 dollars.

​@@phillipsmom6252 - Blinds have a very small Thermal Reflection Value. Especially cheap ones that aren't designed optimally, or with as optimal of materials. Foil is far better. Or, foil taped to foam insulation boards, or at least a stack of cardboard sheets. The more pretty stuff is much more expensive, and is also generally far less effective. If your room is already doing okay as far as the heat goes, then sure.

Outside will be more effective

That's what I noticed too. Good looking kitty.

I dont wear those in the house

😂 😂 😂

And it works fine?

César López don’t you hate it when they don’t reply

@@CesarLopez-xm7in I'm new'ish to this, my 2nd year trying it, but I've done the Foil taped straight to the window and I always thought it helped the interior of the room feel cooler, but the window itself gets quite warm. Because of this, I started to wonder how much was I saving, really. Or am I just moving the heat problem closer to the window instead of the floor, bed, couch, etc. I was doing some research on it some more just today, and I was seeing cardboard more and more in my research and now I'm starting to wonder if the cardboard helps in some way. I know cardboard doesn't transfer heat through it very well, so it's sort of a dampener of heat flow. Where as Aluminum is a reflector (around 95% reflected) of radiant heat only. Aluminum doesn't do much for stopping conductive (through solids) heat transfer, and we all know this if you consider most computer heat sinks are aluminum. So I start to wonder maybe aluminum + cardboard helps as a combo, but I don't know how much the improvement is, yet.

NICE!

That's what I'm going to try. That way I can take them down during the nicer temps and save them to reuse.

Me too. Reconstituted Polystyrene foam boards, coated in, something shiny. There are boards than come with a shiny side, but they're not at my hardware store so yea. I'm not sure how well just cardboard and foil would do. I know you can stack the cardboard and also have foil on both sides, but the boards are good because they can slide in and out of place, because they're thick, and don't bend at all, so I like that idea. Also you can paint the other side to match the wall colour or a black curtain or whatever. You can also use car front windscreen shades, but for me that works out to be more expensive than other options. The 2 windows are huge, so I really wanna make sure they are decently insulated.

LMFOA! I was struggling, it wouldn't rip.

😂 of course I am.

@@DarkDarkPrincess well then I have nothing to worry about. Are you single

​@@will1867 Duh!

@@DarkDarkPrincess well I didn't know. I would have thought some one who is as beautiful would have been in a relationship or married

@@will1867 nope just a Karen with issues
