Double Bubble Reflective Foil Insulation: (4 X 50 Ft Roll) Industrial Strength Radiant Barrier, Commercial Grade Thermal Insulation for Weatherproofing Garages, Attics, Sheds, RV Windows, More

I used this in my Rv to make an barrier between the windows and shades. And it has worked out great! I even cut out some to cover the roof vent/ fans and the sun dome in the shower. Has made a big difference on hot days camping at beach..will see in time how it holds up. 5 stars so far easy to use and cut..

I purchased 6 rolls of this to insulate a 40' shipping container for our construction trailer office & kitchenette space. The thin profile and excellent radiant heat block really makes a big difference keeping heat out in summer and inside in winter.

We use for our Travel Trailer Camper windows when in Florida to keep heat out. It works wonderfully. You get quite a huge roll so can use for many other purposes . We put in our windows before leaving for vacation. It stays in the window nicely while traveling. When we arrive in Florida the RV is not as hot and air conditioning works must faster to cool down. Love this stuff.

I’m I glad I decided to purchase this product instead of some of the cheaper options available. It handled similarly to rigid insulation which made installation so much easier not to mention increased R-value. My attic is now almost 70 degrees which before would have been close to freezing. I recommend lapping the seams and using tape primer before sealing with tape.

Used it to replace a rug under a table in an RV! Mush warmer and a lot easier to clean!

Great product. We used this in our RV wind shield and side winders and helps a lot to keep the hot sun out (which in turn keeps it cooler in summer). We also used to replace insulation that came out when repairing parts in ceiling of our house. Again great product.

easy to work with, wish they published.the 'R' value, i doubled it up and it works great

I bought it to make custom window screens for my RV. We live in Las Vegas where the sun can be outrageous. Since then I have found many uses for it insulating, cushioning, wrapping, etc, etc. 50 ft. is probably a lifetime supply but it'd great stuff.
