coatings sales increased $ 291 million or 5% ( 5 % ) in 2005 .sales increased 3% ( 3 % ) due to higher selling prices across all businesses except automotive ; 1% ( 1 % ) due to improved volumes as increases in our aerospace , architectural and original equipment automotive businesses offset volume declines in automotive refinish and industrial coatings ; and 1% ( 1 % ) due to the positive effects of foreign currency translation .operating income decreased $ 168 million in 2005 .the adverse impact of inflation totaled $ 315 million , of which $ 245 million was attributable to higher raw material costs .higher year-over-year selling prices increased operating earnings by $ 169 million .coatings operating earnings were reduced by the $ 132 million charge for the cost of the marvin legal settlement net of insurance recoveries .other factors increasing coatings operating income in 2005 were the increased sales volumes described above , manufacturing efficiencies , formula cost reductions and higher other income .glass sales increased $ 33 million or 1% ( 1 % ) in 2005 .sales increased 1% ( 1 % ) due to improved volumes as increases in our automotive replacement glass , insurance and services and performance glazings ( flat glass ) businesses offset volume declines in our fiber glass and automotive original equipment glass businesses .the positive effects of foreign currency translation were largely offset by lower selling prices primarily in our automotive replacement glass and automotive original equipment businesses .operating income decreased $ 113 million in 2005 .the federal glass class action antitrust legal settlement of $ 61 million , the $ 49 million impact of rising natural gas costs and the absence of the $ 19 million gain in 2004 from the sale/ leaseback of precious metal combined to account for a reduction in operating earnings of $ 129 million .the remaining year-over-year increase in glass operating earnings of $ 16 million resulted primarily from improved manufacturing efficiencies and lower overhead costs exceeding the adverse impact of other inflation .our continuing efforts in 2005 to position the fiber glass business for future growth in profitability were adversely impacted by the rise in fourth quarter natural gas prices , slightly lower year-over-year sales , lower equity earnings due to weaker pricing in the asian electronics market , and the absence of the $ 19 million gain which occurred in 2004 stemming from the sale/ leaseback of precious metals .despite high energy costs , we expect fiber glass earnings to improve in 2006 because of price strengthening in the asian electronics market , which began to occur in the fourth quarter of 2005 , increased cost reduction initiatives and the positive impact resulting from the start up of our new joint venture in china .this joint venture will produce high labor content fiber glass reinforcement products and take advantage of lower labor costs , allowing us to refocus our u.s .production capacity on higher margin direct process products .the 2005 operating earnings of our north american automotive oem glass business declined by $ 30 million compared with 2004 .significant structural changes continue to occur in the north american automotive industry , including the loss of u.s .market share by general motors and ford .this has created a very challenging and competitive environment for all suppliers to the domestic oems , including our business .about half of the decline in earnings resulted from the impact of rising natural gas costs , particularly in the fourth quarter , combined with the traditional adverse impact of year-over-year sales price reductions producing a decline in earnings that exceeded our successful efforts to reduce manufacturing costs .the other half of the 2005 decline was due to lower sales volumes and mix and higher new program launch costs .the challenging competitive environment and high energy prices will continue in 2006 .our business is working in 2006 to improve its performance through increased manufacturing efficiencies , structural cost reduction initiatives , focusing on profitable growth opportunities and improving our sales mix .chemicals sales increased $ 364 million or 18% ( 18 % ) in 2005 .sales increased 21% ( 21 % ) due to higher selling prices , primarily for chlor-alkali products , and 1% ( 1 % ) due to the combination of an acquisition in our optical products business and the positive effects of foreign currency translation .total volumes declined 4% ( 4 % ) as volume increases in optical products were more than offset by volume declines in chlor-alkali and fine chemicals .volume in chlor-alkali products and silicas were adversely impacted in the third and fourth quarters by the hurricanes .operating income increased $ 160 million in 2005 .the primary factor increasing operating income was the record high selling prices in chlor-alkali .factors decreasing operating income were higher inflation , including $ 136 million due to increased energy and ethylene costs ; $ 34 million of direct costs related to the impact of the hurricanes ; $ 27 million due to the asset impairment charge related to our fine chemicals business ; lower sales volumes ; higher manufacturing costs and increased environmental expenses .the increase in chemicals operating earnings occurred primarily through the first eight months of 2005 .the hurricanes hit in september impacting volumes and costs in september through november and contributing to the rise in natural gas prices which lowered fourth quarter chemicals earnings by $ 58 million , almost 57% ( 57 % ) of the full year impact of higher natural gas prices .the damage caused by hurricane rita resulted in the shutdown of our lake charles , la chemical plant for a total of eight days in september and an additional five 18 2005 ppg annual report and form 10-k .
