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

I ordered the 8ft piece because I wanted to put it across my three panels of sliding doors that go across my living room. The sun comes onto that side of the house after 12:30 and really heats things up. Prior to this I had used mylar sheets clipped to the curtains. They worked some, but I wanted something thicker. This has a really nice thickness and I have just stood it between the curtains and the glass when the sun is shining hot. Great product.

Such a life saver for the texas heat. My bedroom window is the magnet of all texas sun light and heat. This has not only blacked out my room just how I love it and allowed me to finally have a cold room that requires me to use a blanket at night. Way better option then buying the cling on blackout for windows. Extremely easy to put in and tape down. Would recommend this for anyone needing to blackout a room and cool that room off.

Good deal with velcro stickers and tape to secure film. Comes in wide sheets so you can cut to size. Wish it was a little thicker but does work well to cut heat.

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.

This has been a game changer to control the heat coming from the front 3 van windows. Easy to cut. Rolls up when not in use. Flexible to work withHighly recommend.

Why did you pick this product vs others?:One package of velcro hook tabs works but the next package doesn't. It's soft cloth. No velcro. Now I have to go out to get velcro strips. Very disappointed. No quality control. Will not purchase from this company again.

Package comes fold, so there are creases that are hard to get out quickly.

I live in an apartment that used to be an attic. Poor insulation and I melt every summer and freeze every winter. I put some of this in the skylight of my bedroom and in my kitchen windows and it’s made such a big difference. My expectations were very low so I am very happy with the results. The weather here is getting hot and it’s comfortable in all rooms. I also would normally have three AC’s running but only need one now since the cold air seems to be circulating correctly.
