Window Insulation for Summer Heat, Reflective Insulation Roll 24 in X 10 Feet, Double-Sided Aluminum Foam Core Radiant Barrier Kit with Tape for RV Windows Garage Door

Used this along with styrofoam, straw, and a plastic tote to create a shelter for a stray outside cat. Easy to work with. Easy to cut with normal scissors.

I live in an older home with single pane windows. My electric bill was extremely high from the sun beaming in. I tried room darkening curtains and tint. Neither helped. Once I used this product my electric bill dropped significantly! Would definitely recommend for home and RV windows!

As it is not noted in the item details, I mention it here: it's 2 mm thicksoft and flexible, but not too flimsy. I believe it has 2 layers (not 3 as said in the description)It's folded, not rolled, but if you role it and let it sit for a week or so before using, the creases might open.

Used this kit to insulate an old molded plastic dog house for a stray kitty that's been in our yard. Did the trick -easy to work with. Good quality for the price with handy extras.

Nothing to dislike.

One of the reasons I selected this product was that it described it and showed it as a roll (without creases and wrinkles). What I received did not look at all like the photos or description. What was received was a folded sheet with wrinkles, creases, delaminations and impressions from the tape. When cutting it for my application I found out it is not square as well. I also did not find anything that appears to be cotton in the product.

I put this up on the majority of the windows, 2 skylights, and a sliding glass door. OH.M.G.!!! I am DELIGHTED the massive difference in temperature this has made. Ahhh, relief! So dark and cool in my house finally. Should be a great summer this year!

I am sure it probably works fine, but it is wrinkled all throughout. We were using it for a backdrop in a window and will look terrible with wrinkles!
