That's the brainwashing page I was referring to.

Comparing a noreflective product to a reflective product based solely on R value doesn’t help you decide how the products will perform. R value is not the only consideration with respect to Reflectix. That’s why its reflective properties are mentioned.

I do know that Reflectix works really well for temporary use for windows because I use it. DW made a roll bag and we simply roll up the window coverings in the AM if we want lgiht. The product is light and easy to store or easy attached with velcro.

Whether it is the best for your use is up to you to figure out, but use more than R value.

R 1.1 still is some insulation. I think you can compare it to multi-folded newspaper, where for reflection you can use cooking foil.
My point is that the manufacturer is posting specifications that don't apply to the product.

Reflectix resists thermal transfer in 2 modes: conduction and radiation.

The conductive resistance between solid surfaces is R value, easily measured, and has a standard definition for performance. If you put reflextix under your mattress, R value is all you get.

When at least one surface of reflectix "sees air" radiation is resisted. This is hard to measure, and is dependent on temperature, humidity, distance and color of absorbing object (clothes or skin). For covering windows in hot or cold weather, it reflects most radiated heat back and improves radiant comfort. How much? Depends on conditions. That's about all you can say with truth in advertising.

I post this to further explain to others how the product works, not to convince the OP of anything.

OP, do your own performance tests and let us know as others have.
