Reflextic, yes Ive seen that crap, as you read it says " like R6" just
like insulating paint says its "like R" whatever. The key work is "Like"
it is not a certified rating, don`t you even wonder why Reflextic has
different " like" ratings for different applications. Get a Cerfified
insulation, one that is industry accepted and known, Fiberglass. And
best is something designed for your job.
