500 sqft of 1/4 inch Solid NASA Tech Heavy Duty Platinum Reflective Foam Core Reflective Insulation Barrier Attic Foil

I used this against existing paneling inside and did do a 1/2” air gap before putting new paneling over it. Upon reading numerous articles about air gaps, I chose to have one just to be safe as Some said without air gap the r factor would be nil . It easily went up with a staple gun and I got foil tape to seal the seams! A 250 foot roll covers the equivalent of 7-8 pieces of paneling Can’t wait to see my energy bills drop!!!

Didn't want to deal with batt insulation, I thought this might drop a few degrees. Put it up and put in a thermometer to monitor and averaged a 20° drop. (130°+ to 106°highest)

Arrived early ,easy to apply, very pleased with the product.

Insulated the van and was very happy with the product

It went on easily flush against the studs and is waterproof.

I used in my slides in my fifth wheel. Made a huge difference in heating it.

Product was good, for the part I did receive on time. Shipped the portion back that didn't come in on time, only gave me half my credit. I'm out $$$

Building experts around the US have shown in lab tests that the Correct R value is actually about 1.0 not 15 as claimed. If you install multiple layers and can maintain and air gap on both sides and seal perfectly, the R value of the entire wall may approach 10. sheetrock as an R value of approx 1.0 also.
