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.
@marklefler4007 there is a 1 inch gap between the metal and the foil.
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
Came here to say exactly this. It's mind-blowing how many people don't know how to properly use IR thermometers. I saw a video of a guy who recharged the AC in his car, and he genuinely believed the air temperature coming out of his vents after the fact was 17° F while holding the IR thermometer a few inches away from the air vent for a prolonged period of time, ignoring the fact that the condensate on the evaporator would be frozen solid blocking airflow. 🤦♂️
Infrared thermometers have good accuracy when measuring most objects, but shiny, reflective surfaces can be a challenge.
Wong infrared sees color temperature and color are relative, how do you think space scientists measure objects in space not by temperature by the color spectrum it emits.
@@michaeljennings6647no 😂 it reflects you need a solid it can absorb and give a proper reading. It has to have tape or something for it to be accurate!
@@michaeljennings6647you’re talking a flir camera not a laser thermometer
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.
I really want to know how this does when it is cold outside....
Not worth a damn, I would imagine, without heaters going.
It deffo helps keep the cold from coming in also. I've fitted bubble foil in a wood outbuilding between the thick outer and inner layers of woodwall. Before I put the bubble foil in, the temperature was a lot lower within the space when it was cold than it is now after foil instalation. Better still, now when a heater is on in this out buiding, instead of losing the heat, the foil traps the hot air inside keeping it warmer much longer, which is great here in Scotland..
My fave part of this foil is, that it doesn't have ability to hold moisture like most insulation, therefore I never need worry about it becoming wet and mouldy or deteriorating behind the walls where I cannot see. The foil can act to give you cooler space or hotter. Your choice which you want!😎
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.
But I would have thought you would want to measure the temp of the room, right? Doesn't that mean the insulation is blocking the transfer of the heat from the roof to the room meaning it's working?
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 !
By chance did your solution work? It’s sweltering in TX.
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.
What if it's possible to put it on the outside walls instead?? Maybe even hide it behind some plywood??
Can you double it and see more lower temp results or a single layer is sufficient?
Good for indoor grow houses too 😂
THANK YOU!!!
The shirt ad conversation dilutes the content need of the video. Drop it
Now your phone wont work ?
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
yes I think it would help you...put it around all your windows and maybe even tape it to your walls etc....good luck....I hate the heat
Better test would be against s open wall because it’s baking behind the radiant
YOU COULD HAVE R16 VALUE if you had a 1-2 inch air gap instead of it pressed against the metal.....
It does have a 1 inch gap it is stapled to the rough sawn 1xs that the metal is screwed to. They are 1 inch thick so I stapled to them for that reason so it wasn't straight against it cause that kinda defeats the purpose some.
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.
Thanks...
rigid foam insulation would be cheaper and work better
Thank you
Hey Doc, can you take my temperature over the inter webs.
Probably
Do you have an air gap?
Yes there is a 1inch perling board that the metal is attached to. I stapled the bubble foil to that. So there is a 1 inch gap between the metal and the foil insulation.
@@projectdiy873 can this foil bubble insulation be used under carpets ?
@smallfeet4581 honestly I have never thought about it. I would venture to say no but you have to do your homework with your situation.
put the reflective side towards the metal.
Both sides are reflective
Dose it block your cellular service
No
does this work for windows?
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?
It is hard for me to give an exact answer without seeing exactly what you have going on. But as long as there is no moisture going to get it there mold should not be an issue.
@@projectdiy873 I have colder room as I said than the other rooms and In this room if the moisture gets high and cold without enough heating, there is specific corner I get mould in. Therefore I am thinking about solution to get this room warmer to save energy costs and I am afraid of getting mould between this insulation and the wall and maybe I cannot notice it. Thx in advance for your help
@@Ronaldo-ou9vd I'm like you , wanting to help make a room a few degrees warmer (anything will be an improvement) but I want it under the carpet , is this stuff ok for under carpets do you know ? Cheers
@@smallfeet4581
Useless under the carpet, it requires an airspace between it and the heat source you want to reflect. Works best directly opposite or parallel to the source, at least .75 inches. It's best at blocking a heat source like the hot sun or hot roof, or reflecting body heat to warm up in a small confined area like a dog house, or inside lining of a jacket. Also excellent in a double layer below the subfloor with air gaps to keep heat from escaping when cold outside. For a bedroom just get a ceramic or infrared space heater, they warm quick, less than $100, and energy efficient. Check your windows for drafts and weather strip, and or plastic shrink wrap them for the winter. plastic over a window with that sealed air in between is like a storm window, keeps bugs out too.
No, not that way.
You are so beautiful
