Flat AC panels had many versitile applications -  some may have been
used in the WTC.  At one time in early 70's, Johns Manville had a whole
framing system for "storefront construction" with Insulated AC panels
with high level exterior finish, extruded aluminum mullions and etc.,
which could use glass panels in there for whatever amount of vision
glass was desired for the storefront..

AC was also used to construct pipes for water distribution systems here.
There was a J-M plant which manufactured such pipes located in Green
Cove Springs, FL.  Toward the end, such pipes were about universally
coated on the inside with epoxy.

Also, corrugated AC panels were fairly widely used for some years for
both roofs and siding on industrial type buildings.

 JB> yeah it's a budget wall cladding material

 CA>> you may be correct.

Yes, he is correct, even here in the US, for awhile. - -

Thin sheets of AC -  maybe a bit more than 1/8" thick were used in this
part of the country for a number of years - -

Shingled rectangular sheets with a slight texture on outside face - as
an overlay for wood frame construction houses where the the wood siding
planks or exposed wood shingle siding had deteriorated.

As "Lifetime Shingles" even for new construction back in the late 40's -
sort of an octagon exposed pattern to the sheets.  I think also used
back then and maybe to early 50's as replacement roofing where
composition shingles or worse had been.

First part -  about the same here - - plenty houses that old still have
AC siding and AC "lifetime shingle" roofs.  Those products are not used
now for new construction. There may be replacement products here which
use glass fibers, just for repairs of existing applications.  I dunno
for sure.
