US Energy Products 48 in. x 25 ft. Double Bubble Reflective Insulation

I live in the Southwest Deserts of the U.S. where it gets very hot in the Summer. Yesterday was the hottest day this year so far, so I wanted to try it out. I had placed a section over a window on the backside of the house, a window which usually emits a lot of heat during the afternoon. No heat was emitted with that insulation over the window. Amazing! I also used Velcro to hang a section in the sliding glass door during the heat of the day. It worked marvelously. So, I will be using it on all of the appropriate areas in the house. I order another roll yesterday. This is a 5-start product. NOTE: The Velcro tape I used was not the best quality product, so I ended up using Super Glue to attach the Velcro tape to the insulation and on the frame of the SGD. A higher quality Velcro tape may not need to be glued in place.

First time I bought this product I used it to line the inside of a well water pump house. Unrolled it and stapled it to the sides. I then cut a section and stapled it to the door. It keeps the pump house well insulated and easy to heat in the winter, plus it looks nice. Then I bought another roll and have used it under my bathtub, for crawl space doors, to line part of my green house. Very versatile and easy to use. This spring I redid my chicken house that is over 100 years old. It looked great, but the ceiling looked bad. I thought about using paneling to spruce it up a little,but decided instead to use this. I got the 4 ft by 25 ft roll and it covered the ceiling easily. We stapled it up and finished with some silver duct tape and it looks nice. I think it will be a big help come this winter as it reflects heat. I've bought different sizes (2 ft & 4 ft) for different projects. This stuff is so handy and easily cut to keep out drafts in the oddest of places, and is something I have kept on hand for over 15 years for different projects. Love this product.

The bubble insulation was easy to lay out with a magic marker and simple to cut and trim with a pair of basic 8" Multipurpose Scissors. One roll was perfect for my 2015 Thor Vegas 24.1 with 2 Ft. to spare. 4 Ft. is wide enough to cover the windshield from top to bottom. I measured the windows and added 1 inch to the length and width of each cover. 2 1/2 inch radius worked well for all of the corners. The screens were removed and each cover was popped into place with very little additional trimming. I numbered each cover in the upper left corner starting with the drivers window and going clockwise around the coach. The covers all stay in place with the exception of the windshield which stays in place with a 1/4" x 1" piece of pine trim bowed in place from top to bottom in the middle of the windshield. I was surprised by the drastic reduction of propane consumption which appears to be 25 to 35% for me. When not in use the covers store under the mattress of the drop-down bunk.

We live in our RV full time; Michigan in summer and Arizona in winter. Black RV+large windows+hot sun= need insulation! We cut pieces to fit behind window blinds on south and west side and pressed large pieces to fit behind windshield shade.It's really remarkable how much less the A/C units run now, great reflection of the sun's heat. Also keeps the rig warmer on cool mountain nights with just the small space heater running. Easy to remove and replace or to roll up and stash away for travel.Great inexpensive window insulation for home, car or RV. Highly recommended.

Purchased to custom fit window shades for an RV. Package arrived quickly and undamaged. Very light weight material, but is sturdy enough for intended purpose. Was able to measure and cut pieces for 12 windows of our Class A from the 25' roll. Originally thought cut edges would need to be taped but product seems sturdy enough so will forego the taping for now. There was a noticeable temperature difference as all windows were covered. Very happy

The windows inside my boat cabin and the rear of my house.

It's going to be nice to be able to use it one day

this product versus the reflectix brand, that i usually buy: although this did the job, i would not buy it again. this is sightly cheaper in materials, with larger, more shallow circle imprints, and overall feels less substantial and weighty. but that is not my biggest problem with this roll i got.the roll appeared to have been manufactured, and then immediately rolled up, maybe still warm. so when unrolled, the whole thing seemed to gave gotten stretched into the rounded shape that, when i tried to flatten, created creases and ripples every couple inches. which really made this product less rigid when used as insulation on a window, and way less able to lie flat on the window, and stay tucked tight against it.so it works, but lacks the best qualities of reflectix brand: neat look installed, tight fit installed, stable when installed.
