Do they give specifications on R values and insulation? The second may be
the same but did not do whatever has to be done to say they are Energy
Star
compliant. You probably have to do testing a pay a fee for the use of the
name.



They have detailed specs in a PDF. It looks impressive, but I guess I would
have to compare it to the other one. I'd rather do my taxes than grind
through u and r factors.
