                      Georgia Gulf Reports Second
             Quarter Net Income of $.30 Per Diluted Share


    ATLANTA--(BUSINESS WIRE)--July 28, 2005--Georgia Gulf Corporation
(NYSE: GGC) today reported net income of $10.2 million or $.30 per
diluted share on sales of $584.2 million for the second quarter of
2005. This compares to net income of $29.7 million or $.90 per diluted
share on sales of $522.3 million for the second quarter of 2004. Net
income declined primarily as a result of the impact of the Company's
planned and unplanned plant outages, lower aromatics margins, and
significantly lower chlorovinyls sales volumes, which were due in part
to the outages as well as a significant reduction of inventories by
customers. These results also reflect higher overall sales prices as
well as improved margins for vinyl resins and caustic soda.
    "While the second quarter has typically been a seasonally strong
quarter, our results included several items which significantly
reduced our bottom line," said Ed Schmitt, chairman, president and
CEO, Georgia Gulf. "The costs from our plant outages were higher than
anticipated, and we also had to work through higher-priced inventories
and raw materials purchase commitments. In addition, our customers
reduced inventories as sales prices for several products fell
throughout the quarter.
    "As we look forward to the third quarter, we don't expect plant
outages or our customers' reduction of inventories to impact
profitability to the same degree as in the second quarter. Although we
expect raw materials and energy prices to remain volatile, we
anticipate third quarter 2005 earnings will significantly improve over
second quarter 2005 earnings."
    Comparing sequential quarters, second quarter net income of $10.2
million or $.30 per diluted share on sales of $584.2 million decreased
compared to the first quarter of 2005 net income of $38.7 million or
$1.13 per diluted share on sales of $645.4 million. The impact of the
Company's planned and unplanned plant outages, lower aromatics margins
and overall lower sales volumes contributed to the decline compared to
the previous quarter.
    For the six months ended June 30, 2005, net income was flat
compared to the same period last year. Net income of $48.9 million or
$1.43 per diluted share on sales of $1.2 billion compared to net
income of $48.5 million or $1.47 per diluted share on sales of $1.0
billion for the first half of 2004. While sales prices were 36 percent
higher than last year's sales prices, raw materials costs were up
significantly and sales volumes declined by 11 percent.

    Chlorovinyls

    Chlorovinyls segment second quarter of 2005 operating income of
$36.0 million decreased compared to the second quarter of 2004
operating income of $53.0 million. This $17.0 million decline in
operating income was primarily due to the plant outages, which
contributed to a 22 percent decrease in sales volumes. However,
chlorovinyls margins increased in the second quarter of 2005 compared
to the second quarter of 2004.
    Comparing sequential quarters, chlorovinyls operating income
decreased from $59.0 million in the first quarter of 2005 to $36.0
million in the second quarter of 2005. The lower operating income was
a result of the negative impact of the plant outages and lower sales
volumes. Chlorovinyls margins expanded in the second quarter of 2005
compared to the first quarter of 2005.
    For the six months ended June 30, 2005, chlorovinyls operating
income slightly increased to $95.0 million from $91.4 million in the
same period of 2004 as the increased margins more than offset the
plant outage costs and lower sales volumes.

    Aromatics

    The second quarter of 2005 aromatics operating loss of $8.8
million, a decline from second quarter of 2004 operating income of
$6.0 million, was a result of having to work through higher-priced
aromatics inventories and purchase commitments. Higher sales prices
did not offset higher raw materials costs.
    Compared to the first quarter of 2005, operating income decreased
significantly from $14.3 million to a loss of $8.8 million in the
second quarter of 2005. This decrease reflects 13 percent lower sales
volumes and 7 percent lower sales prices. However, the largest factor
was having to work through higher-priced aromatics inventories and
purchase commitments in the face of decreasing raw materials and sales
prices for the Company's products.
    For the six months ended June 30, 2005, aromatics operating income
decreased to $5.5 million from $9.8 million in the same period last
year primarily as a result of 45 percent higher raw materials costs,
which more than offset overall higher sales prices and cumene volumes.
