Reflectix still claiming R4.2 for its bubble wrap – my HVAC guy is hooked
After reading up a bit on this site, I am worried that my HVAC person is installing the wrong product on the metal ductwork that he is now hooking up. As I understand it, Reflectix bubble wrap might have some benefit in a very hot unconditioned attic where the ducts are carrying cold air. But in my case, the opposite is true: the ducts are carrying hot air only and they are located in a cozy spray foamed attic. Mold formation is not an issue here (the basement is a different story, alas).
My installer is half-done and while the attention to detail is far superior to what the previous installer must have had, I already notice that the ductwork, 20 feet of it, plus the main supply plenums are quite warm to the touch when the system is running.
The Reflectix product has “R 4.2, 6.0 when installed with an airspace” written all over it so I am sure my installer has confidence he is doing the right thing. How can I demonstrate to him that I am not getting R 4 — after he has used like 6 rolls of the stuff already and has 2 more ready to be used to complete the job? I can’t believe that they would be allowed to market the product as r 4.2 if the actually R value is closer to 1.0. Why is there no class action suit?
