Questions & Answers
If you say no, the product turns into a conductor. Furthermore, there is no R- in this product. value.
The true answer is that, regardless of what the manufacturers claim, the R- The applicability of the value depends on it. A radiant barrier is a material that blocks the sun's rays from passing through it. This means it reflects (with some loss) what it is being reflected with (hot or cold). It works in the same way that baking a potato in aluminum foil does. Because the foil is in direct contact with the potato, heat will radiate inward around the entire surface of the potato. It does, however, prevent heat from easily escaping once it has been absorbed by the potato's mass, and it stabilizes by creating an air gap around the skin from escaping vapors. As a result, there is virtually no insulation factor. However, if you use this in an application where a significant air gap can be maintained, the heated air will be mostly contained in that gap (the radiant side will be affected by the thermal energy, while the opposite will be much less so); After that, the issue is: What is the best way to dissipate the thermal energy that has accumulated in the gap? br> br>I used this radiant barrier on the underside of my patio metal roof, which is as hot as the roof itself where the radiant barrier comes into contact with it. The heat on the underside is negligible when I allow the radiant barrier to gradually droop to about 4" in the center between joists/supports. The heat is trapped in the air gap and vents at the eaves allow it to escape to the outside. Having said that, blocking unwanted thermal radiation at the initial barrier is the most effective way to keep it outside your structure and away from the area you're trying to control. This radiant barrier might be a good secondary 'insulator,' but I'd start with good primary insulation and keep the thermal energy blocked as much as possible at the exterior walls/roof.

I used this bright, shiny foil to line the ceiling of my garage. I stapled it to the beams, which were spaced 24 inches apart. Although this product isn't labeled as an insulation, it is. I did it for the sake of appearances, but it also serves as insulation. My garage walls had been insulated, paneled, and painted, but the open beamed ceiling appeared to be unfinished. It would be too time consuming to drywall, panel, and paint. I used 3-M Scotch tape to tape the seams after stapling it to the beams. Foil tape with the letter M on it. Another advantage is that the light that is reflected is very bright. By the light of a single candle, I believe I could work in the garage. Because the foil contains nylon threads that give it incredible strength, it must be perfectly aligned before stapling or waves will appear.
This is exactly what I was looking for in terms of a low-cost way to keep my garage warm in the winter. While I'm sure that using this in conjunction with traditional insulation would have been preferable, I was on a tight budget, so this sufficed. It does a good job of keeping the heat in and making the room more comfortable. We'll see if putting in an air conditioner keeps the garage cool in the summer.
I needed tough material for a shed/shop project that would reflect the radiant energy of the summer sun back to space while also retaining generated BTUs in the winter. This radiant barrier was durable, reinforced, and flexible to work with, which were all requirements I had. For this exterior application, I used galvanized staples to secure the product. It's also worth noting that this radiant barrier has been incised to allow for airflow, which is required in this unconditioned space.
This is a fantastic product; it's thick enough to do the job, but it's also easy to work with. If it's not perfectly straight, it's very forgiving. If necessary, it can be removed and reapplied. I can't tell yet if it will make a significant difference in our cooling costs because it isn't fully installed in the attic, but it appears to be doing so already. In a few months, when the temperature rises above 100 degrees, I'll know. With the price tag, it's well worth the money, even if I have to install it myself.
In Colorado, I used it to line a shed. The goal was to keep the heat in while keeping the cold out. I seam sealed all joints with aluminized tape to keep air and bugs out, and it has worked well so far for the price. That is likely more critical than the heat barrier itself.
It fulfills all of my requirements and meets all of my expectations.
It's not particularly thick, but it does the job.
