The projection screen market has traditionally been divided among several
manufacturers, however not equally.

In the past, the major suppliers to theaters have been Hurley on the East
Coast and Stewart on the West.  These two have covered probably over half
the market, with the remainder being divided up among the others, including
Tecknikote.  Draper, Da-Lite, Tecknikote, and some manufacturers in other
countries concentrated on the commercial/industrial market, and Da-Lite
especially also aimed at the consumer (home) market.

Today, all manufacturers, including the big theatrical screen players are
looking very closely at the very rapidly growing "home theater" market.  As
a result, the slices of the marketing pie are now quite different (in terms
of the proportions of each company's business) than they have been
traditionally.

Regarding any silver screen, and especially used theatrical screens, check
them carefully with the tests I suggested previously.  If a screen has been
removed from a theater, and you are thinking of "cutting it up" to make
several smaller screens, consider a couple of point.

First, the screen is probably not clean.  Sodas and other missiles hurled at
a screen by unruly audiences, can ruin them very quickly.  Aluminized
"silver" screens are very difficult to clean, and easily permanently
stained.  This is the main reason why a theater would want to take down and
sell an expensive silver screen.

The coating on these screens is somewhat fragile.  If the screen is left
rolled up for  long period of time, unrolling it may result in cracks and
peeling of the surface.  Also, the aluminum flakes can "oxidize" just from
being exposed to the atmosphere for a long period of time.  This results in
a darkening and reduction in reflectance properties.

Therefore, before paying for such a screen, make sure that you can examine
it unrolled.
