Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Basis of Presentation	Note 1 - Organization and basis of presentation:
	Organization - At March 31, 2015, Valhi, Inc. (NYSE: VHI) held approximately 50% of our outstanding common stock and NL Industries, Inc. (NYSE: NL) held approximately 30% of our common stock, Valhi owned approximately 83% of NL’s outstanding common stock and a wholly-owned subsidiary of Contran Corporation held approximately 93% of Valhi’s outstanding common stock.  Substantially all of Contran’s outstanding voting stock is held by family trusts established for the benefit of Lisa K. Simmons and Serena Simmons Connelly, daughters of Harold C. Simmons, and their children (for which Ms. Lisa Simmons and Ms. Connelly are co-trustees) or is held directly by Ms. Lisa Simmons and Ms. Connelly or persons or entities related to them, including their step-mother Annette C. Simmons, the widow of Mr. Simmons. Prior to his death in December 2013, Mr. Simmons served as sole trustee of the family trusts.  Under a voting agreement entered into by all of the voting stockholders of Contran, effective in February 2014 and as amended, the size of the board of directors of Contran was fixed at five members, Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons (and in the event of their death, their heirs) each has the right to designate one of the five members of the Contran board and the remaining two members of the Contran board must consist of members of Contran management. Ms. Lisa Simmons, Ms. Connelly, and Ms. Annette Simmons each serve as members of the Contran board.  The voting agreement expires in February 2017 (unless Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons otherwise unanimously agree), and the ability of Ms. Lisa Simmons, Ms. Connelly, and Ms. Annette Simmons to each designate one member of the Contran board is dependent upon each of their continued beneficial ownership of at least 5% of the combined voting stock of Contran.  Consequently, Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons may be deemed to control Contran, Valhi, NL and us.
	Basis of presentation - The unaudited Condensed Consolidated Financial Statements contained in this Quarterly Report have been prepared on the same basis as the audited Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2014 that we filed with the Securities and Exchange Commission (SEC) on March 12, 2015 (2014 Annual Report).  In our opinion, we have made all necessary adjustments (which include only normal recurring adjustments) in order to state fairly, in all material respects, our consolidated financial position, results of operations and cash flows as of the dates and for the periods presented.  We have condensed the Consolidated Balance Sheet and Statement of Stockholders’ Equity at December 31, 2014 contained in this Quarterly Report as compared to our audited Consolidated Financial Statements at that date, and we have omitted certain information and footnote disclosures (including those related to the Consolidated Balance Sheet at December 31, 2014) normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP).  Our results of operations for the interim period ended March 31, 2015 may not be indicative of our operating results for the full year.  The Condensed Consolidated Financial Statements contained in this Quarterly Report should be read in conjunction with our 2014 Consolidated Financial Statements contained in our 2014 Annual Report.

Marketable Securities	Note 4 - Marketable securities:
	Our marketable securities consist of investments in the publicly-traded shares of related parties: Valhi, NL and CompX International Inc. NL owns a majority of CompX’s outstanding common stock.  All of our marketable securities are accounted for as available-for-sale securities, which are carried at fair value using quoted market prices in active markets for each marketable security, and represent a Level 1 input within the fair value hierarchy.  See Note 13.  Because we have classified all of our marketable securities as available-for-sale, any unrealized gains or losses on the securities are recognized through other comprehensive income, net of deferred income taxes.

	Total		$	10.8	$	15.4	$	(4.6	)
	At December 31, 2014 and March 31, 2015, we held approximately 1.7 million shares of Valhi’s common stock.  We also held a nominal number of shares of CompX and NL common stocks.  At December 31, 2014 and March 31, 2015, the quoted per share market price of Valhi’s common stock was $6.41 and $6.23, respectively.
	With respect to our investment in Valhi stock, our cost basis has exceeded its market value since March 2014, but we consider such decline in market price to be temporary at March 31, 2015.  We considered all available evidence in reaching this conclusion, including our ability and intent to hold this investment for a reasonable period of time sufficient for the recovery of fair value, as evidenced by the amount of liquidity we currently have with cash on hand.  We will continue to monitor the quoted market price for this investment.  In this regard, as of April 30, 2015, the aggregate quoted market price for our shares of Valhi common stock was $4.0 million less than our aggregate cost basis.  If we conclude in the future that a decline in value of one or more of these securities was other than temporary, we would recognize impairment through an income statement charge at that time.  Such income statement impairment charge would be offset in other comprehensive income by the reversal of the previously recognized unrealized losses to the extent they were previously recognized in accumulated other comprehensive income.
	The Valhi, CompX and NL common stocks we own are subject to the restrictions on resale pursuant to certain provisions of SEC Rule 144.  In addition, as a majority-owned subsidiary of Valhi we cannot vote our shares of Valhi common stock under Delaware General Corporation Law, but we do receive dividends from Valhi on these shares, when declared and paid.

	Term loan – During the first three months of 2015, we made our required quarterly principal payment of $.9 million.  The average interest rate on the term loan borrowings as of and for the quarter ended March 31, 2015 was 4.75%.  The carrying value of the term loan at March 31, 2015 includes unamortized original issue discount of $1.4 million.
	Revolving credit facilities - Our European revolving credit facility requires the maintenance of certain financial ratios, and one of such requirements is based on the ratio of net debt to last twelve months earnings before income tax, interest, depreciation and amortization expense (EBITDA) of the borrowers.  Based upon the borrowers’ last twelve months EBITDA as of March 31, 2015 and the net debt to EBITDA financial test, our borrowing availability at March 31, 2015 is approximately 59% of the credit facility, or €71 million ($77 million).  In addition, at March 31, 2015 we had approximately $94.8 million available for borrowing under our North American revolving facility.

	Tax authorities are examining certain of our U.S. and non-U.S. tax returns and have or may propose tax deficiencies, including penalties and interest.  Because of the inherent uncertainties involved in settlement initiatives and court and tax proceedings, we cannot guarantee that these matters will be resolved in our favor, and therefore our potential exposure, if any, is also uncertain.  We believe we have adequate accruals for additional taxes and related interest expense which could ultimately result from tax examinations.  We believe the ultimate disposition of tax examinations should not have a material adverse effect on our consolidated financial position, results of operations or liquidity.  We currently estimate that our unrecognized tax benefits will not change materially during the next twelve months.

	Certain of our sales generated by our non-U.S. operations are denominated in U.S. dollars.  We periodically use currency forward contracts to manage a very nominal portion of currency exchange rate risk associated with trade receivables denominated in a currency other than the holder’s functional currency or similar exchange rate risk associated with future sales.  We have not entered into these contracts for trading or speculative purposes in the past, nor do we currently anticipate entering into such contracts for trading or speculative purposes in the future.  Derivatives used to hedge forecasted transactions and specific cash flows associated with financial assets and liabilities denominated in currencies other than the U.S. dollar and which meet the criteria for hedge accounting are designated as cash flow hedges.  Consequently, the effective portion of gains and losses is deferred as a component of accumulated other comprehensive income and is recognized in earnings at the time the hedged item affects earnings.  Contracts that do not meet the criteria for hedge accounting are marked-to-market at each balance sheet date with any resulting gain or loss recognized in income currently as part of net currency transaction gains and losses.  The fair value of the currency forward contracts is determined using Level 1 inputs based on the currency spot forward rates quoted by banks or currency dealers.
	At March 31, 2015, we had currency forward contracts to exchange:
	—	an aggregate €15.0 million for an equivalent value of Norwegian kroner at exchange rates ranging from kroner 8.53 to kroner 8.56 per euro.  These contracts with DnB Nor Bank ASA mature at a rate of €5.0 million per quarter from June 2015 through December 2015 and
	—	an aggregate $16.2 million for an equivalent value of Norwegian kroner at exchange rates ranging from kroner 6.75 to kroner 7.11 per U.S. dollar.  These contracts with DnB Nor Bank ASA mature at a rate of $2.7 to $5.0 million per month in certain months from May 2015 to December 2015.
	The estimated aggregate fair value of our currency forward contracts at March 31, 2015 was a $4.5 million net liability which is recognized as part of accounts payable and accrued liabilities in our Condensed Consolidated Balance Sheet.  There is also a corresponding net $4.5 million currency transaction loss recognized in our Condensed Consolidated Statement of Operations.  We are not currently using hedge accounting for our outstanding currency forward contracts at March 31, 2015, and we did not use hedge accounting for any of such contracts we previously held in 2014.  Accordingly, changes in the aggregate fair value of currency forward contracts we hold are recognized as a currency transaction gain or loss.
	The following table presents the financial instruments that are not carried at fair value but which require fair value disclosure as of December 31, 2014 and March 31, 2015.

	Common stockholders' equity		781.1				1,508.70				718.5			1,465.80
	At March 31, 2015, the estimated market price of our term loan was $1,012.50 per $1,000 principal amount.  The fair value of our term loan is based on quoted market prices; however, these quoted market prices represent Level 2 inputs because the markets in which the term loan trades were not active.  The fair value of our common stockholders’ equity is based upon quoted market prices at each balance sheet date, which represent Level 1 inputs.  Due to their near-term maturities, the carrying amounts of accounts receivable and accounts payable are considered equivalent to fair value.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Accounting Pronouncements	Note 14 - Recent accounting pronouncements:
	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606).  This standard replaces existing revenue recognition guidance, which in many cases was tailored for specific industries, with a uniform accounting standard applicable to all industries and transactions.  The new standard is effective for us beginning with the first quarter of 2017.  Entities may elect to adopt ASU No. 2014-09 retrospectively for all periods for all contracts and transactions which occurred during the period (with a few exceptions for practical expediency) or retrospectively with a cumulative effect recognized as of the date of adoption.  ASU No. 2014-09 is a fundamental rewriting of existing GAAP with respect to revenue recognition, and we are still evaluating the effect the Standard will have on our Consolidated Financial Statements.  In addition, we have not yet determined the method we will use to adopt the Standard.
	In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30):  Simplifying the Presentation of Debt Issuance Costs, which requires unamortized debt issuance costs (or deferred financing costs) to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount.  Currently, such unamortized debt issue costs are generally presented as a noncurrent asset.  However, to the extent an entity has unamortized debt issuance costs associated with an unfunded debt liability, such as an undrawn revolving line of credit, such unamortized debt issue costs would continue to be recognized as an asset since there is no liability recognized from which such unamortized debt issue costs can be deducted.  The guidance in the new standard is limited to the presentation of debt issuance costs and does not affect the recognition, measurement or amortization of debt issuance costs; therefore, the standard will not have a material effect on our Condensed Consolidated Financial Statements.  The standard is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted and the new guidance will be applied on a retrospective basis, although we have not yet determined when we will adopt the standard.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization	Organization - At March 31, 2015, Valhi, Inc. (NYSE: VHI) held approximately 50% of our outstanding common stock and NL Industries, Inc. (NYSE: NL) held approximately 30% of our common stock, Valhi owned approximately 83% of NL’s outstanding common stock and a wholly-owned subsidiary of Contran Corporation held approximately 93% of Valhi’s outstanding common stock.  Substantially all of Contran’s outstanding voting stock is held by family trusts established for the benefit of Lisa K. Simmons and Serena Simmons Connelly, daughters of Harold C. Simmons, and their children (for which Ms. Lisa Simmons and Ms. Connelly are co-trustees) or is held directly by Ms. Lisa Simmons and Ms. Connelly or persons or entities related to them, including their step-mother Annette C. Simmons, the widow of Mr. Simmons. Prior to his death in December 2013, Mr. Simmons served as sole trustee of the family trusts.  Under a voting agreement entered into by all of the voting stockholders of Contran, effective in February 2014 and as amended, the size of the board of directors of Contran was fixed at five members, Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons (and in the event of their death, their heirs) each has the right to designate one of the five members of the Contran board and the remaining two members of the Contran board must consist of members of Contran management. Ms. Lisa Simmons, Ms. Connelly, and Ms. Annette Simmons each serve as members of the Contran board.  The voting agreement expires in February 2017 (unless Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons otherwise unanimously agree), and the ability of Ms. Lisa Simmons, Ms. Connelly, and Ms. Annette Simmons to each designate one member of the Contran board is dependent upon each of their continued beneficial ownership of at least 5% of the combined voting stock of Contran.  Consequently, Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons may be deemed to control Contran, Valhi, NL and us.
Basis of Presentation	Basis of presentation - The unaudited Condensed Consolidated Financial Statements contained in this Quarterly Report have been prepared on the same basis as the audited Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2014 that we filed with the Securities and Exchange Commission (SEC) on March 12, 2015 (2014 Annual Report).  In our opinion, we have made all necessary adjustments (which include only normal recurring adjustments) in order to state fairly, in all material respects, our consolidated financial position, results of operations and cash flows as of the dates and for the periods presented.  We have condensed the Consolidated Balance Sheet and Statement of Stockholders’ Equity at December 31, 2014 contained in this Quarterly Report as compared to our audited Consolidated Financial Statements at that date, and we have omitted certain information and footnote disclosures (including those related to the Consolidated Balance Sheet at December 31, 2014) normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP).  Our results of operations for the interim period ended March 31, 2015 may not be indicative of our operating results for the full year.  The Condensed Consolidated Financial Statements contained in this Quarterly Report should be read in conjunction with our 2014 Consolidated Financial Statements contained in our 2014 Annual Report.
Derivatives	We periodically use currency forward contracts to manage a very nominal portion of currency exchange rate risk associated with trade receivables denominated in a currency other than the holder’s functional currency or similar exchange rate risk associated with future sales.  We have not entered into these contracts for trading or speculative purposes in the past, nor do we currently anticipate entering into such contracts for trading or speculative purposes in the future.  Derivatives used to hedge forecasted transactions and specific cash flows associated with financial assets and liabilities denominated in currencies other than the U.S. dollar and which meet the criteria for hedge accounting are designated as cash flow hedges.  Consequently, the effective portion of gains and losses is deferred as a component of accumulated other comprehensive income and is recognized in earnings at the time the hedged item affects earnings.  Contracts that do not meet the criteria for hedge accounting are marked-to-market at each balance sheet date with any resulting gain or loss recognized in income currently as part of net currency transaction gains and losses.
New Accounting Pronouncements, Policy	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606).  This standard replaces existing revenue recognition guidance, which in many cases was tailored for specific industries, with a uniform accounting standard applicable to all industries and transactions.  The new standard is effective for us beginning with the first quarter of 2017.  Entities may elect to adopt ASU No. 2014-09 retrospectively for all periods for all contracts and transactions which occurred during the period (with a few exceptions for practical expediency) or retrospectively with a cumulative effect recognized as of the date of adoption.  ASU No. 2014-09 is a fundamental rewriting of existing GAAP with respect to revenue recognition, and we are still evaluating the effect the Standard will have on our Consolidated Financial Statements.  In addition, we have not yet determined the method we will use to adopt the Standard.
	In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30):  Simplifying the Presentation of Debt Issuance Costs, which requires unamortized debt issuance costs (or deferred financing costs) to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount.  Currently, such unamortized debt issue costs are generally presented as a noncurrent asset.  However, to the extent an entity has unamortized debt issuance costs associated with an unfunded debt liability, such as an undrawn revolving line of credit, such unamortized debt issue costs would continue to be recognized as an asset since there is no liability recognized from which such unamortized debt issue costs can be deducted.  The guidance in the new standard is limited to the presentation of debt issuance costs and does not affect the recognition, measurement or amortization of debt issuance costs; therefore, the standard will not have a material effect on our Condensed Consolidated Financial Statements.  The standard is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years.
