   Georgia Gulf Reports Second Quarter Net Income of $1.15 Per Diluted Share;
         Includes Unrealized Loss of $.21 Per Share Related to Proposed
                               Royal Acquisition


     ATLANTA--(BUSINESS WIRE)--July 27, 2006--Georgia Gulf Corporation (NYSE:
GGC) today reported net income of $39.4 million or $1.15 per diluted share on
sales of $602.2 million for the second quarter of 2006. These results include an
unrealized loss of $.21 per share due to the Company's foreign exchange hedge
for the proposed acquisition of Royal Group Technologies. Second quarter of 2006
net income increased significantly compared to the second quarter of 2005 net
income of $10.2 million or $.30 per diluted share on sales of $584.2 million,
which included the negative impact of the Company's chloralkali plant outages of
$.50 per share. Compared to the second quarter of 2005, overall chlorovinyls
sales prices and sales volumes increased during the second quarter of 2006
resulting in record quarterly operating income for this segment.
     "We are very pleased to report our highest ever quarterly chlorovinyls
operating income of $83.7 million and one of our highest quarters for overall
operating income of $75.4 million," said Ed Schmitt, chairman, president and
CEO, Georgia Gulf Corporation. "The strong performance resulted from increased
year-over-year sales prices and high operating rates for our vinyl resins and
caustic soda businesses.
     "As for the third quarter of 2006, we expect continued strong performance
in our chlorovinyls business even though increased raw materials costs are
expected to lower our third quarter results compared to our second quarter
results. In addition, we will be focusing on completing the acquisition of Royal
Group Technologies, which we previously announced on June 9, 2006."
     Second quarter 2006 net income of $39.4 million or $1.15 per diluted share
on sales of $602.2 million compares favorably to first quarter 2006 net income
of $33.7 million or $.98 per diluted share on sales of $567.9 million. The
improvement reflects higher sales volumes for vinyl resins and vinyl compounds
and lower energy costs, which more than offset lower sales prices for vinyl
resins and vinyl compounds and higher raw materials costs, specifically for
benzene and propylene.
     For the six months ended June 30, 2006, net income compares favorably to
the same period last year. Net income of $73.1 million or $2.12 per diluted
share on sales of $1.2 billion compared to net income of $48.9 million or $1.43
per diluted share on sales of $1.2 billion for the first half of 2005. Higher
sales prices and sales volumes in chlorovinyls more than offset declining
performance in our aromatics business and higher natural gas, ethylene and
propylene costs as well as the impact of our chloralkali plant outages in the
second quarter of 2005.

     Chlorovinyls

     Georgia Gulf's chlorovinyls business provided record-setting second quarter
of 2006 operating income of $83.7 million compared to second quarter of 2005
operating income of $36.0 million, which included the adverse impact from the
Company's chloralkali plant outages in 2005. The improvement in chlorovinyls
during the second quarter of 2006 compared to the second quarter of 2005
reflects higher sales volumes and sales prices for chlorovinyls products, which
more than offset higher ethylene costs.
     Comparing sequential quarters, chlorovinyls operating income increased from
$75.7 million to $83.7 million. This increase was the result of increased sales
volumes for chlorovinyls products and lower energy costs, which outpaced lower
chlorovinyls sales prices and higher ethylene costs.
     For the six months ended June 30, 2006, chlorovinyls operating income
increased to $159.4 million from $95.0 million for the same period of 2005 as
higher sales prices outpaced higher ethylene and natural gas costs and the
impact of our chloralkali plant outages in the second quarter of 2005.

     Aromatics

     Georgia Gulf's aromatics business had a lower operating loss of $0.5
million for the second quarter of 2006 compared to an operating loss of $8.8
million for the second quarter of 2005. The improvement was the result of lower
benzene costs, which more than offset overall lower aromatics sales volumes and
higher propylene costs.
     Comparing sequential quarters, the aromatics business operating loss of
$0.5 million for the second quarter of 2006 improved from the operating loss of
$5.0 million for the first quarter of 2006 reflecting improved sales prices
which outpaced higher raw materials costs.
     For the six months ended June 30, 2006, the aromatics business experienced
an operating loss of $5.4 million, which was a decline from the operating income
of $5.5 million in the same period of 2005. The decline was a result of
significantly lower sales volumes and lower sales prices for all aromatics
products.
