Reflective Bubble Foil Insulation/Does It Work???

In this video I'm going to show and prove to you the amount of heat that is reflected using the foil bubble insulation. This does not give a very big R value but it reflects a lot of heat.

Engineer here. It would have worked better if you stapled it to/between the rafters instead of where you did. Placing it right against the roof lets heat conduct through the foil, where a small air gap removes conduction, and lets the foil reflect the infrared heat back out the roof. Also pointing an infrared gun at the foil will not give you a reading of the foil. It will give you a reading of the infrared mostly reflected off the foil. Try putting soemthing like a lable on the foil and measure that. Or ust mease something in the room to get its temperature.

u have to put a spot of electrical tape on the silver or it will only tell you the temperature of the room behind you it will not give a good temp, emissivity is gonna fool you

Infrared thermometers have good accuracy when measuring most objects, but shiny, reflective surfaces can be a challenge.

What bad can happen if I just stick it on top of the wallpaper in my attic?

It became my office now, I’m fine with the “aesthetics” 😂

The heat in the summer is too much. I cannot renovate right now.

Are you really using an infrared thermometer to measure the temperature of a surface designed to reflect infrared ? You are just measuring the temperature of the room when you do that ahah!
Also, taking the temperature of the metal that is behind the insulation and comparing it to the temperature of the insulation (even if it's the actual temperature, not the IR thermometer reading) is not a good way to demonstrate the effectiveness of the insulation. The metal will be hotter than if there was no insulation because one one of its face is insulated and can't radiate heat as much. You need to compare it to just bare metal.

Can you double it and see more lower temp results or a single layer is sufficient?

Nice Video !I have an 8 by 10 steel shed I was given and I is in nice shape ! It is like a torture chamber sweat box right now it is so hot !I was going to just take some single bubble foil roll like you have and liquid nails it right onto inside of shed ceiling .I do not see how it could not help..I don't wanna pit a bunch of money into insulating it, just cool it down a little for stories by riding mower etc !

I really want to know how this does when it is cold outside....

[moisestapia]

What if it's possible to put it on the outside walls instead?? Maybe even hide it behind some plywood??

You need a thermal flux sensor to measure how good it is properly. I've got most of an extension built 20 years ago covered in this and it's useless compared to a decent thickness of PIR foam or similar. Alreflex 2L2 claims R value of 1.56m2K/W with a thickness of only 3mm. If this were true, it would make its thermal conductivity better than vacuum insulation which is just not credible and nigh on impossible.

That really isn't valuable information. Of course the thing with the sun shining on it is going to be hotter than the thing without the sun shining on it. How hot does the space get? That's the only measure of how useful it is.

Thank you for this video. Do you think this can work for walls and floors of an apartment? I'm really desperate in the summer, even with the ac on my bedroom doesn't stay cool enough to sleep well in

Better test would be against s open wall because it’s baking behind the radiant

The shirt ad conversation dilutes the content need of the video. Drop it

YOU COULD HAVE R16 VALUE if you had a 1-2 inch air gap instead of it pressed against the

[huggybear]

rigid foam insulation would be cheaper and work better

[robertthomas]

Hey Doc, can you take my temperature over the inter webs.

[MP-zvfm]

put the reflective side towards the metal.

Hi Dude, my bedroom is colder than the other rooms, can I use this on the corner of this room to kepp it warmer? Could Mould be formed under it?
