EXHIBIT 99.3

             UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL DATA

    The following unaudited pro forma combined, condensed financial statements
have been derived by the application of pro forma adjustments to the historical
financial statements of Georgia Gulf and the vinyls business of CONDEA Vista
included as exhibits to this Form 8-K. The pro forma balance sheet gives effect
to the offering of the 10 3/8% notes, the refinancing of Georgia Gulf's senior
credit facility, the purchase of the co-generation facility under the terms of
the operating lease and the acquisition of the vinyls business of CONDEA Vista
as if these transactions occurred on September 30, 1999. The pro forma statement
of income for the fiscal year ended December 31, 1998 and the nine months ended
September 30, 1999 gives effect to the offering of the 10 3/8% notes, the
refinancing of Georgia Gulf's senior credit facility, the purchase of the
co-generation facility under the terms of the operating lease and the
acquisition of the vinyls business of CONDEA Vista as if these transactions had
occurred on January 1, 1998. The pro forma statement of income for the twelve
months ended September 30, 1999 gives effect to the offering of the 10 3/8%
notes, the refinancing of Georgia Gulf's senior credit facility, the purchase of
the co-generation facility under the terms of the operating lease and the
acquisition of the vinyls business of CONDEA Vista as if these transactions
occurred on October 1, 1998. The pro forma balance sheet and the pro forma
statements of income should not be considered indicative of actual results that
would have been achieved had the transactions described above been consummated
on the dates or for the periods indicated. Also, the pro forma balance sheet
data and statements of income should not be viewed as indicative of Georgia
Gulf's balance sheet data or results of operations as of any future date or for
any future period. The pro forma combined financial statements should be read in
conjunction with the "Management's Discussion and Analysis of Financial
Condition and Results of Operations of Georgia Gulf Corporation", "Management's
Discussion and Analysis of Financial Condition and Results of Operations of the
Vinyls Business of CONDEA Vista Company" and the financial statements and
related notes included elsewhere in this Form 8-K to which this exhibit is
