Subject: Reflectivity of white paint vs. mylar
A recent post said that white paint is nearly as reflective as mylar. I
sell a variety of radiant barrier materials for a living. The plain fact is
that the absolute BEST reflector is a mirror finish. Mylar will be
significantly better as a reflector than white paint.

For the sake of clarity let me point out I was comparing mirror GLASS with
white paint. Silvered glass reflects only 88 - 93 of incident light
according to my trusty, if outdated, copy of the CRC Handbook. Certain white
paints reflect 85 - 98 percent of incident light. Do you have reflection
coifficients for your mylars?
