What I find difficult to believe is that there ISN'T a table (cheat
sheet) available somewhere that lists the interglas numbers and the
amurrican equivelant. *F'rinstance:
(all numbers and descriptions just made up)
92110 * - *5.2 oz/yd plain weave
92125 * - *8.75 oz/yd 2 x 2 twill
etc.

Ummm, the chart I linked has exactly that, except weights are in g/sq
m instead of oz/yd (easy conversion). Only problem, is there are NO
direct equivalents for 92125 or 92110 (or the 92145 I was also looking
for, in addition to several other common Interglas weaves...) and
that's the REAL problem.

(in case you didn't look at it from my earlier post...) has the
comparison chart that has the US equals for them in the column second
from the left--IF one actually exists.

I myself am not comfortable with using something other than exactly
what the manufacture says (I find 'close' to be unacceptable in this
regard) when it comes to structure but hey, what's the worse that
could happen?
