         SPARTECH PREVIEWS OPERATING RESULTS FOR FOURTH QUARTER 2005

                        -----------------------------

ST. LOUIS, NOVEMBER 16, 2005 - Spartech Corporation (NYSE: SEH) announced
today that sales for its recently completed fourth quarter were $367
million, up 20% from last year's fourth quarter including approximately 7%
related to two additional months of sales from the 2004 VPI acquisition and
a strong impact of price and mix affects. Sales for the full year were
$1,398 million, an increase of 25% from 2004. In addition, the company
generated strong cash flows from operations for the second consecutive
quarter enabling debt pay-down of $46 million in the quarter and $84 million
for the second half.

"Sales were in line with our expectations for the quarter and we continue to
make progress on our restructuring activities," commented President and CEO
George A. Abd. "Our debt pay-down of $84 million in the past six months is
not only the best half year performance but also far exceeds our best
previous performance in any full year of $55 million, demonstrating the
strong cash generation capability of our business as well as our focused
commitment to working capital management."

"While our year end close and audit process are not complete, we are
revising our earnings guidance for the fourth quarter to $0.31-$0.36 per
share before special items, compared to our previous guidance of $0.26-$0.31
before special items. This performance was achieved despite the negative
impact of Hurricane Rita which forced a three week shutdown of our plant in
Lake Charles, Louisiana and the severe price increases and raw material
supply problems initiated by Hurricane Katrina. Contributing to offset those
negatives were unanticipated short term increases in sales to some markets,
specifically manufactured housing and recreational vehicles which were
spurred by the same disasters."

The company substantially completed the consolidation, shutdown, or sale of
the operations it announced in February of 2005. These activities included
the sale of its Corrugated Sheet business in Cornwall, Ontario as well as
the sale of properties in Redlands, CA, Goddard, KS, Conshohoken, PA, and
Taylorville, IL during the quarter as part of its restructuring efforts. The
company announced a further plant shutdown in its September 6 earnings
release which will occur in early 2006.

Mr. Abd further stated, "While we are pleased with our progress in our
restructuring and profit improvement efforts to date, we have significant
concerns related to energy and freight costs, and increasing interest rates
and the affect that those will have on underlying demand in 2006. As a
result we are maintaining our guidance for 2006 of $1.23 to $1.33 diluted
earnings per share before the effect of implementation of stock option
expensing outlined in Statement of Financial Accounting Standards No. 123R."

Spartech is scheduled to present to investors at the First Analysis
Investment Conference in New York on November 17, 2005 and at the Morgan
Stanley Small Cap Chemicals Roundtable also in New York on December 1, 2005.
