Double Bubble Reflective Foil Insulation (24 inch X 25 Ft Roll) Industrial Strength, Commercial Grade, No Tear, Radiant Barrier Wrap for Weatherproofing Attics, Windows, Garages, RV's, Ducts & More! .

Bought this to line the windows in our rv. It does a great job keeping the sun out. Easy to customize for all sizes of windows. Good quality and great value for the money. Have bought before and when I purchase another camper, will need another roll.

Works great for insulation of homeless cat shelters. Please consider helping the homeless cats with a trip to the clinic for a spay/neuter, some food/water, and a tote container, straw, and lined for insulation with this great stuff!

This insulation works GREAT in helping to minimize the extreme heat coming through my windows from the insanely hot southern Arizona sun. I will be buying more to cover the rest of my windows this summer. I use Velcro to attach the insulation to my windows, so it can be easily removed & replied. This stuff has been a lifesaver in helping to reduce my utility bills.

Seems to do what it says my only issue is when put up to light it almost looks like brush strokes like paint on the "foil" sides so I don't know if it's truly reflective or not but as insulation it does a great job. Also it ask me when reviewing the product "adhesion" rating so I put a one start because it has none lol

I placed it in the windows of my travel trailer - really helps block out the summer sun & heat.

Perfect size. Works great in our RV windows.

Good product

I really like this product. I used it for the windows in my motorhome. It has really made a big difference as far as blocking drafts and helping to insulate during the cold weather.
