INSULATION MARKETPLACE SmartSHIELD -10mm Reflective roll, Foam Core Radiant Barrier, Thermal Shield - Engineered Foil (48" x 25ft)

This is a flexible reflective insulation that worked very well in my chicken coop last winter. The reflective coating helped them stay warm enough very little supplementary heat. The material is thin enough to shape and staple in place but still offers a bit of an air barrier between the foil layers.I removed it for the summer but it held up well and I will use it again this year.

It's not magical, but it will provide a noticeable reduction in temperature. I get at least a 6 degree cooling effect compared to none. Before going into our garage you would get hit with a wall of heat, now it just feels warm on above 85 degree days. I bought 3M VHB Foam Tape 4611, 1/4" x 36 yards, Dark Gray, Double-Sided, Permanent, Long-Term Durability, High Temp Resistant to stick it to the garage, running a full line around all the panels and two lines around the left, right and center braces. the most important part was the prep, I used glass cleaner first then 99% isopropyl alcohol to clean all the areas where I put tape. I also wiped down the areas on the insulation where the tape would go with the alcohol. I got the 10mm thick version and I'm very happy with it. I cut it to width of the garage door and stuck the whole panel on. Then I used and long blade to cut the individual panels after it was stuck on the door so I got no gap in between panels. I also used a blade to cut around the door hardware. Although, I wished i had installed it vertically as 48" + 48" is 8', would have saved me time and provided better alignment. I guess the heat got to me.

Easy to cut, is during a great job keeping my boat cool inside, helps the performance of the ac tremendously

If it's important that material but cut to the right size you might want to look elsewhere. I like the material but when I started to measure and cut it to my window size I was disappointed. It's not quite as big as I needed. It's between a half and 3/4 of an inch shy on one dimension. It didn't make it all the way to the edge of the window on one side.

We actually used this as indoor insulation. Easy to unwrap and using contractor staples to attach to the indoor wall. Has ZERO odor! YAY. Foil lined on both sides, so nice! Covered it with wood plank looking polyester curtains so it'll be very easy to clean and keep dust down.
