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 Door

Really works great to keep out summer heat and keep warmth in the winter. Used it on a large window in North Idaho.

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.

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.

The six was perfect! I cut off the length I needed, put the velcro (both sides together) on the top of the window. Lining up the thermal cover and pushed on the velcro. Using the included tape along the frame.That's it a quick 10 minute job Don in 5!

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.

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.

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.
