fowong Reflective Window Insulation Roll, 36" x 10 Ft Window Insulation for Winter, Weatherproofing Aluminum Foil Bubble Thermal Bubble Shield for RV, Roof, Garage Door

I own a Toyhauler with a back garage. It has 3 windows that came with black out covers. The covers even in low outside heat get really hot to the touch and make the garage area (which also doubles as a bedroom with bunkbeds) very warm. I purchased the reflective Insolation roll to place under the black out cover. It took about 4 minutes to install. I cut the reflective roll to fit over my window and about 1.5 inches overlapping the outer edges of the window. I used the included velcro dots, so removing the reflective roll would be easy if I needed too. After installing the reflective roll and replacing the black out cover it was AMAZING what a difference in the cover and room temperature. The reflective roll material is just the right thickness, easy to cut and the velcro dots are very sticky and stay in place. I am happy with this purchase and would recommend.

Placed this in my east-facing window on first 100 degree day and felt a measurable and instant reduction in heat. The material is not too flimsy, easy to work with, and is staying in the window on its own {I can do this with my recessed style of window since the insulation roll is larger than the window and can be pressed in]. Notably, light can still enter, though very diffused. I like this because I can still see if the sun is still up. I plan to buy another roll of this for the West facing window and the house should stay cool at least until our nights are no longer cool, and then just put less strain on the AC. If you wish to save on cooling costs, I do recommend this.

Mine did not come as pictured on Amazon. Mine came folded. Where it was folded, those areas got squished and are mostly flat. The material is easy to cut and the little disks are handy to place it with. The appearance is consistent with what I expected. The thickness is okay. I bought this for my basement windows. When we had 3 weeks of sub zero temps in January, I checked my old basement windows to see how they were doing. There was a solid inch of ice on the inside of every basement window. That’s why I am trying to improve the insulation factor. So far, I have about half of them covered but I will get it finished before winter. I will have plenty of material to insulate other things with when I am done.

My RV came with some fancy magnetic sun shields that began to get scorched in the sun, and started to develop a burning smell that made me wonder if they might not actually melt or ignite at some point.Custom RV window covers, especially for a Class C cab, are more costly than I was in the mood for, and the fancy covers were still a good weight & insulation, so I decided to see if I could modify them by covering the wondow-facing sides with this.It worked brilliantly, for a fraction of the price I would've paid for replacements, and has continued to work for nearly a year

I really do like how easy it is to put together on the windows. No need for tape, the velcro tabs help alot.

I covered my bedroom window with this. It is thinner than I was expecting but it does cut the heat some. I’ll probably look at a thicker product next time.

It is very easy to use and set up. The adhesive circles are really strong. Highly recommend as it’s great quality.

I had a problem with heat coming through my windows on the west side of my home when the sun came around in the afternoon. It added about 20 degrees heat to my hopme, taxing the central air. I installed the insulation on all west side windows and it dropped the temperature by 20 degrees plus. You will have to follow directions and measure your windows correctly when installing. I had no problems. A great purchase.
