Double Reflective Insulation Roll, 23.6" X10' Double-Sided Aluminum Bubble Roll, Rv Window and Window Insulation for Winter and Summer, Garage Door, Roof, Car

I live in a trailer and I'm in the room with the large window. I used these to cover up the window during the summer and it gave me relief of the heat which unfortunately had fried my plants prior to purchase. RIP bamboo shoots and cacti. If I'd had this from the get go they might have made it, but oh well. Keep your house at the temperature you want for less money with these. Things are not as hot during the summer, and during winter you can keep more heat in. Love this product. Also, keeps the signals from the aliens from reaching me while I sleep. JK! Nothing stops them signals.

I used this to line my cat’s tub for outside. I then put straw on top of it to keep her warm. Easy to cut and work with.

We used this to insulate our molded metal garage door and I can't believe how well it worked! Two packages did the whole thing and we had plenty left over to bubble wrap at least five toddlers if the need ever arises. It's just bubble wrap with a reflective silvered film over both sides, so it's light and easy to cut and mount with tape. It came with a bunch of tiny round mounting dots, but I didn't bother messing with those since I've been fooled by promises of two-sided adhesive in the past to disastrous results. Instead, I used silvered tape intended for wrapping ductwork and it matched the insulation that way. Summer is coming, so we'll see how well it holds in the cool air, but it's been holding in the heat from our space heater during these springs storms really well so far.

Rather expensive for what amounts to shiny bubble wrap. Does insulate well. I also bought a larger size for (obviously) a larger window. It's almost blackout, with just a tiny amount of direct sunlight getting through.

I have a different use for this. Very heavy slate squares are coming out of the kitchen and since probably only floor boards under there I'm going to put down double layer of insulation and a rug! Problem resolved. Slate causing floor to settle and take support under house w it

I live at the beach in FL in a circa 1960s building with original AC and windows. During the “feels like 108” days, I couldn’t get it cooler than 77 in my place. I installed this on my two windows that get the afternoon sun and within 30 minutes it dropped from 76 to 73 in the heat of the afternoon. This product works much better than I expected. I really like how lightweight it is and how easy it will be to take down and store once it’s time to open up the windows in the fall. Highly recommend!

I bought this to put in my window that the sun pounds on. It’s amazing how much of a difference having this on. Instant cooling on the inside of the room.
