DGSL Double Reflective Bubble Foil Insulation Foam, 23.6 in X 10 FT Aluminum Foil Thermal Insulation Radiant Barrier for Window, Garage Door, RV, Roof

Not cheap, but definitely worth the price. Helps keep some heat/cold from getting in. 1 layer doesn't block out all the sunlight, blocks out enough tho.

I used this in my greenhouse during freezing rain and cold temperatures when I needed a little extra insulation. I’ve purchased another brand in the past that was slightly thicker, but this still helped keep some of the cold out. I was also covering my plants with flannel sheets and packing blankets, so everything combined made a difference. It’s easy to work with and looks durable enough (I haven't had a problem). The adhesive pieces that came with it didn’t really hold, but honestly I’ve tried other brands with similar results, so I wasn’t expecting a miracle there. Even with the harsh weather, I managed to save most of my plants, so I’d say it did its job when I needed it.

Works great is added insulation to my hot tub.

The use of the word “double” implies a double bubble, in my opinion, but this is a single bubble product. With that being said, it works as well as any other single bubble insulation I’ve used. It’s a decent price and I liked that it came with sticker pieces to attach it with. I use this to insulate packages for shipping and it’s great for slightly warm/cold conditions.

i wanted to try this out on my front windows , my front windows face sun all day until dark i had the window with foil, this worked pretty well but still got hot. the Double reflective bubble foil works better then i thought it would, it decreased the temp coming thu the window by 10 degrees its about 1/4 inch thick , easy to install vs aluminum foil

I was a bit septal but it seems to work good to take the chill off my cat's outside enclosure, I'm thinking about trying some for a window..

This is good quality stuff. I bought it to insulate a small cabinet and it worked exactly how I expected. It was easy to cut to size. Highly recommended.

I rely on reviews often and I am a little disappointed the reviews touted this better than it is. This is about half the thickness of a quality type insulation material. I am including pictures where you can see that it's not fully reflective and the sun shines through it when placed on a window. I had been using a thicker product on my garage door and ran out so I bought this for the price. It was half the thickness and felt much more flimsy. I decided to cover my windows as well to help wih heat loss over winter and to keep it cooler in summer.

El aislante de aluminio esta muy bueno, muy resistente y sí cumple su uso

Works well to insulate and if above a heater reflect well. Easy to install

Disminuye considerablemente el calor.

I have seen many items for garage insulation before ordered this and this is working than other expensive insulation. One thing is not good is adhesive sticker it come with , in -10 degree it fallen off from door. I used some insulation tape which works better. Overall now it keep my garage less cold in winter. Better than before

Muy util
