Accounting Policies [Abstract]
Basis of Presentation and Use of Estimates	Basis of Presentation and Use of Estimates The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (“SEC”) for interim reporting purposes. The results reported in these unaudited condensed consolidated financial statements are not necessarily indicative of results that may be expected for the entire year. These unaudited condensed consolidated financial statements should be read in conjunction with the information contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The year-end condensed balance sheet data was derived from audited financial statements but does not include all disclosures required by US GAAP. The preparation of these unaudited condensed consolidated financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities at the date of the Company’s financial statements. Actual results may differ from these estimates under different assumptions and conditions. Estimates inherent in the preparation of these unaudited condensed consolidated financial statements relate to the collectability of account receivables, the valuation of inventories, estimated earnings on uncompleted contracts, useful lives and potential impairment of long-lived assets. Changes in estimates are reflected in the periods during which they become known. Actual amounts may differ from these estimates and could differ materially. These financial statements reflect all adjustments that in the opinion of management are necessary for a fair statement of the financial position, results of operations and cash flows for the period presented, and are of a normal, recurring nature. The Company has one operating segment, Architectural Glass and Windows, which is also its reporting segment, comprising the design, manufacturing, distribution, marketing and installation of high-specification architectural glass and window product sold to the construction industry.
Principles of Consolidation	Principles of Consolidation These unaudited condensed consolidated financial statements consolidate TGI, its subsidiaries Tecnoglass S.A.S (“TG”), C.I. Energía Solar S.A.S E.S. Windows (“ES”), ES Windows LLC (“ESW LLC”), Tecnoglass LLC (“Tecno LLC”), Tecno RE LLC (“Tecno RE”), GM&P Consulting and Glazing Contractors (“GM&P”), Componenti USA LLC (“Componenti”) and ES Metals SAS (“ES Metals”), which are entities in which we have a controlling financial interest because we hold a majority voting interest. To determine if we hold a controlling financial interest in an entity, we first evaluate if we are required to apply the variable interest entity (“VIE”) model to the entity, otherwise the entity is evaluated under the voting interest model. All significant intercompany accounts and transactions are eliminated in consolidation, including unrealized intercompany profits and losses. The equity method of accounting is used for investments in affiliates and other joint ventures over which the Company has significant influence but does not have effective control.
Derivative Financial Instruments	Derivative Financial Instruments The Company recognizes all derivative financial instruments as either assets or liabilities at fair value on the consolidated balance sheet. The changes in fair value of derivative instruments that are designated and qualify as cash flow hedges, the unrealized gains or losses on the derivatives are recorded in the consolidated statement of comprehensive income. Amounts in Accumulated other comprehensive loss on the consolidated balance sheet are reclassified into the consolidated statement of income in the same period or periods during which the hedged transactions are settled.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In June 2016, FASB issued Accounting Standards Update (ASU) 2016-13, Financial Instruments—Credit Losses (Topic 326). This ASU represents a significant change in the allowance for credit losses accounting model by requiring immediate recognition of management’s estimates of current expected credit losses. Under the prior model, losses were recognized only as they were incurred, which FASB has noted delayed recognition of expected losses that might not yet have met the threshold of being probable. The new model is applicable to all financial instruments that are not accounted for at fair value through net income, thereby bringing consistency in accounting treatment across different types of financial instruments and requiring consideration of a broader range of variables when forming loss estimates. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, (with early application permitted). The FASB has announced that it will issue an update during the fourth quarter of 2019 that will postpone the effective date further into the future. During 2019, the FASB issued ASU 2019-04 and ASU 2019-05 with Codification Improvements to Topic 326, Financial Instruments – Credit Losses. The Company is currently evaluating the potential effect of this ASU on its consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” The amendments under ASU 2017-12 refine and expand hedge accounting requirements for both financial (e.g., interest rate) and commodity risks. Its provisions create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. It also makes certain targeted improvements to simplify the application of hedge accounting guidance. ASU 2017-12 became effective for us in the first quarter of 2019. During the quarter ended September 30, 2019, we entered into foreign currency non-delivery forward and collar contracts which we have designated as cash flow hedges and are accounting for as derivative financial instruments to which we are applying the provisions of ASU 2017-12. Prior to the quarter ended September 30, 2019 we did not have any hedging derivatives and therefore prior periods will not be affected by this pronouncement.
New Accounting Standards Implemented	New Accounting Standards Implemented In February 2016, the FASB issued ASU 2016-02 “Leases (Topic 842)” (“ASU 2016-02”). The FASB issued ASU 2016-02 to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Under ASU 2016-02, a lessee will recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-to-use asset representing its right to use the underlying asset for the lease term. ASU 2016-02 retains a distinction between finance leases (i.e. capital leases under current GAAP) and operating leases. The classification criteria for distinguishing between finance leases and operating leases will be substantially similar to the classification criteria for distinguishing between capital leases and operating leases under current GAAP. The amendments of this ASU are effective for reporting periods beginning after December 15, 2018, which for the Company is the fiscal year beginning January 1, 2019. The Company did not adjust the comparative periods presented as the FASB provided entities the option to instead apply the provisions of the new leases guidance using the modified retrospective application approach. The new standard provided a number of optional practical expedients in transition. We elected the ‘package of practical expedients’, which allowed the company to not reassess our prior conclusions about lease identification, lease classification and direct costs. The new standard also provides practical expedients for an entity’s ongoing accounting. We elected the short-term lease recognition exemption for all leases that qualified, primarily for certain equipment leases that are month-to-month leases. This means, for those leases, we did not recognize right-of-use assets or lease liabilities. We also elected the practical expedient to not separate lease and non-lease components for all classes of underlying assets. We have identified and analyzed our lease portfolio and evaluated the new reporting and disclosure requirements of the new guidance, and our lease-related processes and internal controls. The adoption of this standard had no material impact to the Company’s financial statements, as, under prior guidance, we had recognized capital leases which correspond to the right-of-use asset and lease liability described under the new guidance. This standard does not have a significant impact on our liquidity or on our debt covenant compliance under our current agreements. As of January 1, 2019, the Company had $378 finance lease right-of-use assets related to computing equipment and a lease liability for $380 on its Condensed Consolidated Balance Sheet. As of September 30, 2019, the Company had $449 finance lease right-of-use assets related to computing equipment and a lease liability for $559 on its Condensed Consolidated Balance Sheet. The lease agreements include terms to extend the lease, however the Company does not intend to extend its current leases. The weighted average remaining lease term approximates 2.8 years. The right-of-use assets are depreciated and interest expense from the lease liability are recorded on our Condensed Consolidated Statement of Operations. Additionally, as of September 30, 2019 the Company had a commitment for $66 under operating leases related to short term apartment leases, installation equipment and computing equipment which expire during the current year that have not been capitalized due to their short-term nature. Rental expense from these leases is recognized on our Condensed Consolidated Income Statement as incurred. Finance lease costs, including amortization of the right-of-use assets and interest expense, short term lease cost, and related cashflows have not been material as of September 30, 2019. Leases Accounting Policy We determine if an arrangement is a lease at inception. We include finance lease right-of-use assets as part of property and equipment and the lease liability as part of our current portion of long-term debt and long-term debt on our Condensed Consolidated Balance Sheet. Leases considered short-term are not capitalized, given our election not to recognize right-of-use assets and lease liabilities arising from short-term leases, but instead considered operating leases and the resulting rental expense is recognized on our Condensed Consolidated Statement of Operations as incurred. Finance lease right-of-use assets and lease liabilities are recognized based on the present value of the future lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option.

Leases considered short-term are not capitalized, given our election not to recognize right-of-use assets and lease liabilities arising from short-term leases, but instead considered operating leases and the resulting rental expense is recognized on our Condensed Consolidated Statement of Operations as incurred.
