Wonder if you could make long johns with bubble foil?

Some of these comments shows that lots of people dont need a science class, they were not born with any common sense.

Thanks! I just went around 3 of my upstairs rooms with radiant barrier and was wondering how much it might help. This video gave me my answer.

Can you install this on attic ceiling rafters?

What's better perforated radiant barrier or non perforated for metal roofing?

Still don't understand WHY????? Can you please explain why you would use one vs the other for each application??????!!!!!

Did he cut that foil tape with a knife? Lol

I need a help please. I have colder room in my house and I know that it leaks energy because I think it has thermal bridge on its corner. The room is located in the north direction of the apartment. If I installed such insulation, could it form Mould between the wall and this insulation in this corner while we will not be able to see it? Thx in advance

Current code is R12 where I live and I think that is too low! Where is the mastic sealing of the seams and joints. This feel like only a “code” install which is only the minimum requirement and not the state of the art…full building science. Do better.

What is this supposed to do? Make heating/cooling more effective?

How you use it for concret wall

But.

How long the Radiant Barrier will last?

This is fraud in my opinion. You do not have sunlight in your attic, just UV and UB invisible rays. This experiment is obviously comparing direct heat from a source (Heat lamp), not invisible heat from waves (Radiant). The foil reflects the light.

um... so how much sunlight am i getting in my attic or walls? none? so should i put reflective barrier on the roof? edit: try putting a lid on it...

Can you drywall over it?

Good scientific study because it can easily be replicated to prove or disprove the results, which are dramatic.

I recently insulated my detached garage flat roof by putting 150mm of rockwool insulation sandwiched between the roof and 12mm plasterboard. I dont want to take that all down to apply this as the forst layer. So my question is, can i add this as a layer after the plasterboard? Will it still be effective?

This test represents an attic without a roof? How much infared penatrates a roof?

I would just throw that behind the studs and that’s it it’ll keep the heat in unless you do between every single joist above it’s useless

What does this accomplish

Which stepper .machine you are using

I'm betting if you get a disco ball and lights this stuff would really shine.

I'm wanting to buy that insulation and do it myself. Thanks to you and I won't have to hire a handyman!

The industry leader, Reflectix, states on their website the greatest R value is achieved when there's a 3/4" air gap between it and the batting

I've only seen videos using the single foil layer in attics, and a lot of talk about radiant vs. conductive heat, and air gap. No explanation on the choice of material in this video. Whether a basement or an attic, i assume the goal is he same: In the winter keep the warmth in and tne cold out. The opposite in summer. So why different products?

Thanks so much 🥰

A glaring issue I see here is that with any sort of vapor barrier or radiant barrier, both inside or outside of the wall, you should start the wrap layer at the bottom and all layers above it should overlap it 3" to 6" depending on local codes. By doing it top down you create a seam for potential moisture and condensation to drop into and collect. So I consider this to be improper! So much bad information on CZcams unfortunately.

would this work if i put it on a regular wall?

If the wall is already installed you don't need that

Do you know anything about the varying prices thus qualities ? I was rather dismayed when I discovered they range from 12.00 to aprox. 225.00 a roll

Are there any kind of "tabs" or "washers" you can use to lay on top of the insulation at staple point? Just using the stapler on the insulation makes it very delicate

What can I put ontop of the fiberglass?

I wonder... Does foil create a Faraday cage effect if you have the stuff all around? Thus blocking radio, satellite, cell signal, etc?

Stuff works out side was 90 in my shed was 70 .

Tape seems .

Shouldn't the radiant barrier and fiberglass insulation have an air gap?

all I know one is cheaper than the other.

Yah yah yah yah. No one tells you about mold ,mildew stackybothrius black mold. No no. This is Ronnie . I know a little about mold for 30 years Don't do this. Mold mold jo

Would this also work in reverse? It does right? Radiant energy is radiant energy? Like If I were to try and use this to keep heat in, instead of out, it would also perform better than fiber insulation?

Is it work for mini cold storage about 2m x 3m.?

I would like to see one with just radiant barrel without the fibreglass insulation

Hi sir, how to install if the frame made form metal/ aluminum? Ty

I have a question - I am insulating a wood shed built from a kit. I bought the one that has a white side and the aluminum side (Reflective foam core 1/4 inch insulation barrier roll). Do I face the aluminum side outwards and the white side facing inwards. It is very hot where I live 100+ for many days a year and I want to stop everything I have stored from getting too hot. Am I doing it correctly?

Can I put this inside an air handler?

I made a room inside my shed and I used this to insulate it. It keeps the heat in during the winter and so far it keeps a constant temperature of around 73-75 degrees even when it's been about 90 outside. I keep my window open as well to help with ventilation. I'm in north Florida

I thought there suppose to be a space between insulation and the reflective film but it looks like its wright on it

My cabinets are next toa wall that has really weak insulation or maybe none at all. In the summer, the house can be decently cool, but the cabinet space feels like a heater. Vice versa for the winter. Can installing this aluminum foil help, if I apply directly on the walls within the cabinets?

How is this stuff in the summer time? Does it get too hot?
