I bought this to insulate feral cat houses for some brutal Illinois winters. It is super easy to work with compared to the rigid foam and bubble wrap insulation I used before and was reasonably priced for the roll I got. I will definitely get it again when I run out. Quality and shipping was fast too.

Used a 48x10 roll to make my own window shades for a camping trip. Was great for privacy and helped keep the heat out as to keep my coolers cold. I made a front windshield cover, a rear window cover, both front side windows and then also 2 smaller rear windows for the trunk area, all with 1 roll.

this is NOT bubble wrap reflective garbage, this is foam insulated reflective material which is BETTER.

Installed in minutes, very easy to measure and cut the panel sizes needed. Had a very hot summer and kept our garage several degrees cooler. Very light weight but effective so does its job well without adding strain on the garage door and motor mechanism. Should also work well keeping the garage warmer in the winter. Insulates well. Have left over for other projects such as sun shades for windshields when parked etc. recommended

Wow. I can't believe how well this works. We installed this in our hottest room. We frequently turn on A/C in this room because it scorches in direct sunlight during the day, and the room is situated above the garage. During the night, the rising heat doesn't help with the cooling process.

Then we installed this. It would be like over 90 degrees outside all day. But the room stays cool in mid-70s throughout the day. And we never turn on A/C in this room anymore. I'm fact, my mum uses the blanket bc it's too cold for her. Unbelievable. I know.

When the temperature goes above 100, the room rises to low to mid 80s. Maybe high 80s if the temperature rises higher than normal. We turn the AC on for 30 minutes, turn it off, and the room stays cool for wayyyyyyyyyyyy longer than before.

I am attaching a photo to show what a big difference this makes. It's 97 degrees outside right now at 3:30 p.m. clear skies. But my room temperature is 74.8 degrees. I expect the temperature to rise to low 80s as the day passes by, but look at this huge difference.

This $15 product will save me about $350 in electricity bills this summer. We'll worth the investment.

Product as described. Quality good.

Easy to install as barrier under the carpet in my car. Application was in a C3 corvette. Be sure to get the aluminum tape.

The 3mm is thin. For the second roll I purchased I was looking for the 5to6 mm version but it was only available in very long lengths. My only complaint.

As I was installing I noticed it was reflecting my body heat and broke into a sweat.

As mentioned I purchased a second roll to do the passenger side. For the C3 you will need two rolls to complete a second passenger side and rear compartment. Overall good buy and satisfied
