I talked to Reflextic years ago and asked who did their R value test and
if they had one. They could not, would not , give an answer so I am left
with disbelief. Even if it might possibly perform as their non
independant unverified "claim" states, the cost of reflextic is
excessive compared to indepently proven and tested materials such as
Fiberglass. My view is it is 1/4" bubble-foil wrap claiming to perform
like 2" R6 fiberglass foilfaced duct insulation or Foilfaced 2"
Polyisocyanurate R14.4 foamboard, it does not wash with me. i dont
dought it works but I would just guess it is near R 1-3 per 1/4" at an
excessive cost. The only thing I did not do is purhase and IR test it
because of its higher cost than proven Fiberglass. This is exactly the
same claim Radiant barrier paint makes, radiant barriers are not R
value, it is radiant heat loss which can be done cheaper with Foil faced
fiberglass. Unless I see independant tests I can not believe it, No
independant test leads me to believe it would fail their claim. Everyone
wants their product certified, it is so easy and cheap to do .
