Atlanta, Georgia, April 2, 2007 — Georgia Gulf Corporation (GGC: NYSE) today announced its financial results for the fourth quarter and full year of 2006. Fourth quarter results include Royal Group, which was acquired on October 3, 2006.

For the fourth quarter of 2006, Georgia Gulf reported net sales of $681.5 million compared to $518.9 million for the fourth quarter of 2005. The Company reported a net loss of $47.2 million or $1.38 per diluted share, compared to net income of $18.7 million or $0.55 per diluted share in the fourth quarter of 2005. Discontinued operations generated a loss of $0.10 per share during the fourth quarter of 2006, resulting in a loss of $1.28 per share from continuing operations. This loss from continuing operations was primarily a result of challenging market conditions for Georgia Gulf’s legacy chemical businesses and Royal Group’s building and home improvement products businesses, as well as several non-recurring charges totaling $0.61 per share.

During the fourth quarter, sales prices and sales volumes declined in the Company’s chlorovinyls business compared to the same quarter in the previous year, primarily in the vinyl resins and vinyl compounds product lines. In each of the Company’s building and home improvement products divisions, sales volumes declined compared to the fourth quarter of 2005 due to the continued weakness in the building and renovation markets. In aromatics, sales volumes and sales prices increased compared to the same quarter in the previous year.

Fourth quarter non-recurring items of $0.61 per share include $0.34 per share from valuing Royal Group’s inventory at fair value as of the date of acquisition as required by purchase accounting standards. As a result, the sales of such acquired inventory provided only nominal margin during the fourth quarter. Other non-recurring items included $0.10 per share for acquisition related financing fees,

$0.09 per share for the foreign exchange loss on Canadian dollar forward contracts entered into to hedge the purchase price of the Royal Group acquisition, and $0.08 per share for legal and professional fees.

FIFO inventory accounting for legacy chemical operations negatively impacted earnings per share by approximately $0.14.

For the full year ended December 31, 2006, Georgia Gulf’s net sales were $2.4 billion compared to sales of $2.3 billion for the full year ended December 31, 2005. Net income from continuing operations was $51.8 million or $1.51 per diluted share, compared to net income of $95.5 million or $2.79 per diluted share during 2005. Discontinued operations generated a loss of $.10 per share resulting in net income for the year 2006 of $1.41 per diluted share.

Georgia Gulf’s financial statements for 2006 on Form 10-K were accepted by the Securities and Exchange Commission on March 30, 2007, and are available through EDGAR and on the Company’s Web site.

Commenting on 2006, Mr. Schmitt, Chairman, President and CEO said, “2006 was a very good year for legacy Georgia Gulf considering the downturn in the housing and construction industry during the latter part of the year. Georgia Gulf and Royal Group’s management teams have worked well together to rapidly capture synergies and achieve improvement goals. Together in the last six months we have:

· Significantly reduced debt;

· Disposed of most unprofitable, non-core businesses;

· Consolidated extrusion plants;

· Focused the sales force on new customer opportunities;

· Reduced headcount;

· Leveraged the combined raw material purchasing power of the two companies;

· Begun to utilize Georgia Gulf’s vinyl resins and vinyl compounds formulation expertise;

· Created a new technical service/design team;

· Increased utilization of higher speed extrusion tooling technology; and,

· Reached tentative settlement of Royal Group’s shareholder class actions.”

He concluded saying, “As the construction industry emerges from its downturn, we will be well along in the execution of our integration plan and well positioned to serve our markets. We continue to pursue additional opportunities to improve the Company and reduce debt.”

Asset Sales Drive Significant Debt Reduction, Focus on Core Business

Georgia Gulf reduced debt by $153 million during the fourth quarter of 2006, with approximately $135 million generated through consideration from sales of certain non-core assets of Royal Group. This consideration was well in excess of the $98 million forecasted by Georgia Gulf’s management during its third quarter conference call, as restructuring initiatives progressed more quickly than previously anticipated. The $153 million debt repayment reduces interest expense by approximately $11 million per year. In addition, the amount of the Company’s asset securitization was $34 million lower at year-end compared with the acquisition date.

Management has swiftly taken actions to provide greater focus to Royal Group’s core business activities. The majority of Royal Group’s non-core businesses have now been sold, including most international businesses and the window coverings businesses. The few remaining non-core businesses are expected to be sold during 2007. The combined negative impact on Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) of all non-core businesses totaled approximately $29 million during Royal Group’s fiscal 2006.

“Consideration from asset sales exceeded plan in the fourth quarter as a result of rapidly taking actions to sell Royal Group’s non-core, non-performing business units and assets,” commented Mr. Schmitt.

Georgia Gulf received proceeds of approximately $160 million during the first quarter of 2007, from the sale and lease back of certain Royal Group properties, as well as sales of other Royal Group properties and certain remaining Royal Group non-core businesses. Cumulative proceeds from asset sales since completion of the acquisition on October 3, 2006, have been almost $300 million. Georgia Gulf expects its net debt position to be approximately $1.379 billion as of March 31, 2007, compared to $1.651 billion upon acquisition of Royal Group on October 3, 2006. Accounts receivable asset securitization is expected to be approximately $139 million as of March 31, 2007, compared to $162 million as of October 3, 2006.

“In just six months, we successfully reduced total debt, including our asset securitization, by $295 million,” continued Mr. Schmitt.

Rapidly Progressing With Integration of Royal Group

Commenting on the integration of Royal Group, Mr. Schmitt said that the Company “is ahead of plan with initiatives to capture synergy and improvement opportunities.”

Georgia Gulf estimates that savings related to synergy and improvement programs that have been implemented range from $55 million to $70 million on an annualized basis, excluding the benefit of selling loss generating non-core businesses. These savings programs were largely implemented during the fourth quarter of 2006, with the benefits of these programs expected to be realized in 2007.

Georgia Gulf intends to provide further insight into the outlook for 2007 during its upcoming conference call. Mr. Schmitt noted that “challenging market conditions are expected to persist through 2007, which will overshadow the positive impact of synergy and improvement programs.”

The Royal Group acquisition furthered Georgia Gulf’s chlorovinyls forward integration strategy by providing a growth platform that leverages the Company’s vinyl resins and vinyl compounds formulation expertise, which has been refined over the last 20 years, with Royal Group’s experience and innovative product development.

Tentative Settlement of Class Action Lawsuits

Royal Group and certain of its former officers and former Board members are named defendants in two shareholder class action lawsuits pending in the United States District Court for the Southern District of New York (instituted in December 2004) and the Ontario Superior Court of Justice (instituted February 24, 2006) brought by Royal Group shareholders. Georgia Gulf acting for Royal Group has entered into a stipulation and agreement of settlement with the lead and representative plaintiffs in the cases after a

mediation process among the parties. It is a condition to the settlement that the U.S. and Canadian actions be settled contemporaneously. Under the terms of the global settlement, subject to the approval of both the U.S. and Canadian courts, Royal Group will make a payment of CAD $9 million in cash (or U.S. dollars of $7.7 million based on the exchange rate as of December 31, 2006). There can be no assurance that all conditions to the agreement will be satisfied.

Georgia Gulf

Georgia Gulf Corporation is a leading, integrated North American manufacturer of two chemical lines, chlorovinyls and aromatics, and manufactures vinyl-based building and home improvement products. The Company’s vinyl-based building and home improvement products, marketed under Royal Group brands, include window and door profiles, mouldings, siding, pipe and pipe fittings, deck, fence and rail and outdoor storage buildings. Georgia Gulf, headquartered in Atlanta, Georgia, has manufacturing facilities located throughout North America to provide industry-leading service to customers.

Safe Harbor

This news release contains forward-looking statements subject to the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on management’s assumptions regarding business conditions, and actual results may be materially different. Risks and uncertainties inherent in these assumptions include, but are not limited to difficulties in integrating the recently acquired business of Royal Group, Inc., uncertainties relating to Royal Group’s business and liabilities, uncertainties regarding asset sales, synergies, operating efficiencies and competitive conditions, future global economic conditions, economic conditions in the industries to which our products are sold, industry production capacity, raw materials and energy costs and other factors discussed in the Securities and Exchange Commission filings of Georgia Gulf Corporation, including our annual report on Form 10-K for the year ended December 31, 2006.

Non-GAAP Measures

EBITDA is not a recognized measure under United States generally accepted accounting principles (GAAP). Management believes that, in addition to net income, EBITDA is a useful supplementary measure as it provides investors with an indication of cash available for distribution prior to debt service, capital expenditures, cash income taxes, minority interest and changes in working capital. Investors should be cautioned, however, that EBITDA should not be construed as an alternative to (i) net income determined in accordance with GAAP as an indicator of the Company’s performance or (ii) cash flow from operating, investing and financing activities as a measure of liquidity and cash flow. The Company’s method of calculating EBITDA may differ from other companies and, accordingly, the Company’s EBITDA may not be comparable to measures used by other companies.

Because Georgia Gulf does not predict special items that might occur in the future, and our analyses are developed at a level of detail different than that used to prepare GAAP-based financial measures, Georgia Gulf does not provide reconciliations to GAAP of its forward-looking financial measures.
