Window Insulation for Winter, Reflective Insulation Roll 48 in X 10 Feet, Double-Sided Aluminum Foam Core Radiant Barrier Kit with Tape for RV Windows Garage Door

I've put this over multiple windows that don't get used which felt like heaters all day from mid morning to a bit after after sunset (desert life problems). The difference I felt was immediately noticeable. I ended up finding more spots to use this that I hadn't considered before purchasing and had good success with those as well. It came with both little Velcro pads and the reflective tape. Between all of the insulations I've used a good amount of both and it has all held up great. I really like having the Velcro pads as I have a little inverter nook that I keep covered with this and it allows me to still have easy access to the inverter if I need it (has come in handy twice now). Have more projects in mind and will absolutely be buying more.

These were great for the windows in our RV. Love the tape also but with extreme heat, the tape does still come off the windows, but they really keep the heat out.

Excellent, and thick! I used this to make a custom fitted solar heat shield for my sunroof skylight and it works excellent, I used a foam block as the backplate and a section of this that goes up against the window. Its a lot of material that covers a lot of space

This was one big sheet. I used it to cover the house windows from the cold weather. It did work for heat retention. had to cut it to fit my 3'x3' windows. able to cover 3. The velcro sticky's worked well.

One of the best quality reflectives to help keep the Florida sun & heat out of my minivan.

It’s not on a roll — it comes folded. I used it in my camper, but I don’t think it reflects the sun well enough. I can still feel the heat coming through. I did find it easy to cut and install.

We bought this to cover 2 of the windows in our RV for those bright summer mornings it works great. We just cut it to fit in perfectly so during the day we can remove it.

I trusted the listing. The photo shows a rolled item. I received a very tightly folded air sealed block. I needed the insulation flat and it is heavily wrinkled and unusable. I even put it in the sun to see if heat would relax it. Just like this purchase….a total waste of time. Buyer Beware!!!!!!!!
