Reflective Bubble Foil Insulation/Does It Work??? 

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. 🤦‍♂️

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

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

Not worth a damn, I would imagine, without heaters going.

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?

Probably

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.

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.

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.

No

@marklefler4007 there is a 1 inch gap between the metal and the foil.

Thank you

Both sides are reflective

It's the blue eyes
