Ordered this Smart Shield reflective insulation to prepare for a metal roof and I was amazed at how well this worked to keep the heat off the house. Its July and yes, its roofing time. Sometimes you just do the projects when you can, right? So I ordered this 24"x50ft from Amazon and it made it fine, but when I ordered the 48"x100ft- well, it was undeliverable. Got a refund, and just ordered directly from Smart Shield. They were great! So if you need a lot of this- I suggest going to their website to order. Back to the product review: this is only 3mm, so very thin, but very effective. Also, I have to say how glad I was for cloudy (not rainy) days when putting this stuff up because once the sun hits this, its like looking across the lake or bright white snow- its pretty blinding! And the heat radiating off this can be pretty intense on a hot summer day! Overall, this was comparable to other brands of reflective insulation. I just prefer this over the bubbles. I'm sure there are multiple uses for this- indoors/garage, RV, vehicle, etc. It certainly seems worth the price! Great company to work with, too!

I live in an HOA and needed a white backing so I wouldn't get fined. Even with the white side to the windows it helped cool the west facing, upstairs section of the house tremendously.
(**We're in Texas with no shade and MONTHS of humid 100+ degree temperatures so this was a big deal!)

I love that it's foam and not bubble wrap first of all. Second it's so easy to work with compared to the bubble wrap option.
The foam is easy to cut with a utility knife/razor, scissors were cumbersome but will work too. We used packing tape to attach to the window frame. After a month of use I am definitely happy with the product.

I skirted my RV with it! Easy to put in place, using aluminum foil tape. I also used it to insulate my hot tub. Great find.

Not what I needed, didn't use

I used this product to insulate my travel trailer. It really works well as a insulator of heat, you can feel it blocking the cold the minute you apply it to a surface. It is lightweight and easy to cut with scissors. I can easily attach it with a staple gun without worrying about popping air bubbles. I also created a skirt to go around my rv and it worked for that purpose as well. It's a bit thin so you want to really attach it well so the wind won't take it away.
