Don't know the product, but do they claim anything greater than R5? I heard of one product, 1/4 inch thick, that claimed R20-ABSURD!!! That would revolutionize the insulation industry, destroying all the existing major mfrsThis may be a claim regarding IR reflection or something misleadingWhat you describe sounds like that for a water heater tank-some benefit, nothing profound, depends on your needsBeware all the new environmental, eco-friendly products making incredible claims coming your way-there will be no shortage of themFor the other part of your question, the idea is just that: the air already in there, is trapped, which is what insulations doVapor barriers and house-wraps prevent migration of moisture/air through insulation.
