The problem is the manufacturers are way ahead in testing
combinations. It is rare for 2 or 3 coatings now, most are 2 and 3
minimum. Then throw in a new standard, NAFS. <br>

go further down to page 27 or page 33 on the
pdf numbering. The last paragraph explains
that the coatings on the different glass
surfaces have complicated the library. I
assume the e?.? is the new attempt to keep
track of the different coatings and also which
glass surface they are on.<br clear="none">
You are in the emissivity table. The table
above is the reflective glazing and below is
electrochromic glazing. With a thermopane
there are 4 glass surfaces and the new windows
can have all 3 of these types of coatings and
more in a single unit.<br clear="none">
I suspect you can find the actual meanings

Glass has got very complex in the last few
years and those charts represent products sold
in mid 2006. Our new code asks for much
better performance than these glass types are
capable of. The best of these represented a
window ER of 18 to 20. Our code wanted 25.
Some of the new windows are getting up to an
ER of 30 for a thermopane. That huge bump is
almost all due to coatings and their
arrangement.<br clear="none">
