Ceramic-filled
or so-called ceramic insulating paint additive technologies promoted by several
companies claim to be an”insulating” paint which are used to make exterior house walls
cool have been a nonsensical concept from their outset based upon just one law of
physics. Since insulation and it associated mandatory “R- value” measurement in
the building industries have been long established as the
measure of effectiveness for insulation. This is based on thermal mass
(thickness & density) and in some varieties, effectiveness in trapping air
inside the thick barrier or dense product. Average paint thickness is a
single sheet of paper. Now comes the two sheets of paper thick ceramic-filled
paint (up to ten pieces of paper for some manufacturers), and the claims
of insulation value when used to paint any type of exterior wall.
Buildings coated in this way are claimed to be so cool so as to be
compared to the space shuttle in how it is protected by ceramic tiles in
re-entry to our atmosphere. This is all smoke and mirrors since the very
basis for the R-values claimed cannot possibly be achieved for any substantial
length of time by thousandths of an inch of any paint film with insulation
elements (ceramic or hollow glass) mixed inside of it.
