| Recently Adopted Accounting Standards |
In June 2018, the FASB issued ASU No. 2018-07, “Compensation – Stock Compensation (Topic 718) 505-50, “Equity—Equity-Based Payment to Non-Employees In February 2016, the FASB issued ASU No.
2016-02, “Leases (Topic 842), 2018-01, in July 2018 within ASU Nos. 2018-10 and 2018-11, in December 2018 within ASU No. 2018-20, and in March 2019 within ASU No. 2019-01 (collectively, the standard). The standard requires lessees to recognize operating leases on the balance sheet as a right-of-use asset and a lease liability. The liability is equal to the present value of the lease payments over the remaining lease term. The asset is based on the liability, subject to certain adjustments. Operating leases result in straight-line expense. The Company adopted the standard on January 1, 2019, and elected the transition method of adoption, which allowed the Company to apply the standard as of the beginning of the period of adoption. The Company opted to elect the package of practical expedients to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs, and certain other practical expedients, including the use of hindsight to determine the lease term for existing leases and in assessing impairment of the right-of-use asset, and the exception for short-term leases. For its current classes of underlying assets, the Company did not elect the practical expedient under which the lease components would not be separated from the nonlease components. Nonlease components include certain maintenance services provided by the lessor and the related consideration is specified on a stand-alone basis in the applicable lease agreements. Adoption of the standard had a significant impact on the Company’s condensed consolidated balance sheet due to the recognition of a right-of-use asset and lease liability (current and of $45.8 million and $47.2 million, respectively, upon adoption. As the Company’s leases do not provide an implicit rate that can be readily determined, the Company used its incremental borrowing rate based on the information available at the implementation date in determining the present value of lease payments. non-current) |

| New Accounting Standards Not Yet Adopted |
In August 2018, the FASB issued ASU No. 2018-15, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of FASB Emerging Issues Task Force)” internal-use software license. Under that model, implementation costs are capitalized or expensed depending on the nature of the costs and the project stage during which they are incurred. Capitalized implementation costs are amortized over the term of the associated hosted cloud computing arrangement service contract on a straight-line basis, unless another systematic and rational basis is more representative of the pattern in which the entity expects to benefit from its right to access the hosted software. Capitalized implementation costs would then be assessed for impairment in a manner similar to long-lived assets. The new guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. Entities can choose to adopt the new guidance either prospectively to eligible costs incurred on or after the date the guidance is first applied or retrospectively. The Company will adopt the guidance on January 1, 2020, and does not believe adoption will have a material impact on its financial condition or results of operations.In January 2017, the FASB issued ASU No. 2017-04, “Intangibles—Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment In June 2016, the FASB issued ASU
2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses in Financial Instruments, 2019-04, and May 2019 within ASU No. 2019-05. The ASU amends the guidance on the impairment of financial instruments and adds an impairment model, known as the current expected credit loss (CECL) model. The CECL model requires an entity to recognize its current estimate of all expected credit losses, rather than incurred losses, and applies to trade receivables and other receivables. The CECL model is designed to capture expected credit losses through the establishment of an allowance account, which will be presented as an offset to the amortized cost basis of the related financial asset. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and is applied using the modified-retrospective approach. The Company will adopt the guidance on January 1, 2020. The Company does not believe adoption will have a material impact on its financial condition or results of operations. |

Inventories valued at LIFO
(last-in, first-out), consist of the following (in thousands):
The Company utilizes the LIFO method of accounting related to its Trex Residential wood-alternative decking and residential railing products, which generally provides for the matching of current costs with current revenues. However, under the LIFO method, reductions in annual inventory balances cause a portion of the Company’s cost of sales to be based on historical costs rather than current year costs (LIFO liquidation). Reductions in interim inventory balances expected to be replenished by year-end do not result in a LIFO liquidation. Accordingly, interim LIFO calculations are based, in part, on management’s estimates of expected year-end inventory levels and costs which may differ from actual results. Since inventory levels and costs are subject to factors beyond management’s control, interim results are subject to the final year-end LIFO inventory valuation. As of September 30, 2019, management estimates that interim inventory balances will be replenished by year-end and there were no LIFO inventory liquidations or related impact on cost of sales in the nine months ended September 30, 2019.Inventories valued at lower of cost (FIFO method) and net realizable value were $1.8 million at September 30, 2019 and $2.3 million at December 31, 2018, consisting primarily of raw materials. The Company utilizes the FIFO method of accounting related to its Trex Commercial architectural railing and staging systems for the commercial and multi-family market. |

| Leases |
The Company leases office space, storage warehouses and certain plant equipment under various operating leases. The Company determines if an arrangement is a lease at inception. The arrangement is a lease if it conveys the right to the Company to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. Operating leases are included in operating lease right-of-use (ROU) assets, accrued expenses and other current liabilities, and operating lease liabilities in the condensed consolidated balance sheets. Operating leases with an initial term of 12 months or less are not included in the condensed consolidated balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. ROU assets represent the right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Company gives consideration to instruments with similar characteristics when calculating its incremental borrowing rate. The Company’s operating leases have remaining lease terms of 1 year to 10 years. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.For the nine months ended September 30, 2019, total operating lease cost was $6.3 million. The weighted average remaining lease term and weighted average discount rate at September 30, 2019 were 6.6 years and 3.67%, respectively. The following table includes supplemental cash flow information for the nine months ended September 30, 2019 and supplemental balance sheet information at September 30, 2019 related to operating leases (in thousands):

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and revenue is recognized when or as the Company satisfies the performance obligation. Revenue is recognized at an amount that reflects the consideration to which the entity expects to be entitled in exchange for transferring control of the goods or services to a customer. Trex Residential Products Trex Residential principally generates revenue from the manufacture and sale of its high-performance, low-maintenance, eco-friendly composite decking and residential railing products and accessories. Substantially all of its revenues are from contracts with customers, which are purchase orders of short-term duration of less than one year. Its customers, in turn, sell primarily to the residential market, which includes replacement, remodeling and new construction related to outdoor living products. Trex Residential satisfies its performance obligations at a point in time. The shipment of each product is a separate performance obligation as the customer is able to derive benefit from each product shipped and no performance obligation remains after shipment. Upon shipment of the product, the customer obtains control over the distinct product and Trex Residential satisfies its performance obligation. Any performance obligation that remains unsatisfied at the end of a reporting period is part of a contract that has an original expected duration of one year or less. Any variable consideration related to the unsatisfied performance obligation is allocated wholly to the unsatisfied performance obligation and recognized when the product ships and the performance obligation is satisfied.For each product shipped, the transaction price by product is specified in the purchase order. The Company recognizes revenue on the transaction price less any amount offered under a sales incentive program. The Company recognizes an account receivable (contract asset) for the amount of revenue recognized as it has an unconditional right to consideration at the time of shipment and payment from the customer is due based solely on the passage of time. The Company receives payments from its customers based on the payment terms applicable to each individual contract and the customer pays in accordance with the billing terms specified in the purchase order, which is less than one year. The related accounts receivables are included in “ Accounts receivable, net Trex Residential may offer various sales incentive programs throughout the year. It estimates the amount of sales incentive to allocate to each performance obligation, or product shipped, based on direct sales to the customer. The estimate is updated each reporting period and any changes are allocated to the performance obligations on the same basis as at inception. Changes in estimate allocated to a previously satisfied performance obligation are recognized as a reduction of revenue in the period in which the change occurs under the cumulative catch-up method. In addition to sales incentive programs, Trex Residential may offer a payment discount. It estimates the payment discount that it believes will be taken by the customer based on prior history. Trex Residential pays commissions to certain employees. However, the sales commissions are not directly attributable to identifiable contracts, are discretionary in nature and are based on other factors not related to obtaining a contract, such as individual performance, profitability of the entity, annual sales targets, etc. These costs are included in selling, general and administrative expenses as incurred. Trex Residential does not grant contractual product return rights to customers other than pursuant to its assurance product warranty (see related disclosure on product warranties in Note 18, “ Commitments and Contingencies Trex Commercial Products Trex Commercial generates revenue from the manufacture and sale of its modular and architectural railing and staging systems. All of its revenues are from fixed-price contracts with customers. Trex Commercial contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contract and is, therefore, not distinct. Trex Commercial satisfies its performance obligation over time as work progresses because control is transferred continuously to its customers. Revenue and estimated profit is recognized over time based on the proportion of actual costs incurred to date relative to total estimated costs at completion to measure progress toward satisfying the performance obligation. Incurred costs represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Incurred costs include all direct material, labor, subcontract and certain indirect costs. The Company reviews and updates its estimates regularly and recognizes adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on revenue and estimated profit to date on a contract is recognized in the period the adjustment is identified. Revenues and profits in future periods are recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, the Company recognizes the total loss in the period it is identified. During the nine months ended September 30, 2019, no adjustment to any one contract was material to the Company’s Condensed Consolidated Financial Statements. In accordance with ASC 606-10-50-15, the Company discloses only the transaction price allocated to its remaining performance obligations on contracts with an original duration greater than one year , which was $46.8 million as of September 30, 2019. The Company will recognize this revenue as contracts are completed, which is expected to occur within the next 24 months.The Company recognizes an account receivable (contract asset) for satisfied performance obligations as it has an unconditional right to consideration and payment from the customer is due based solely on the passage of time. The Company receives payments from its customers on the accounts receivable based on the payment terms applicable to each individual contract and the customer pays in less than one year. Accounts receivables are included in “ Accounts receivable, net In addition, the timing of revenue recognition, billings and cash collections may result in revenues in excess of billings and contract retainage (contract assets), and billings in excess of revenues and customer deposits (contract liabilities) in the Condensed Consolidated Balance Sheet. These assets and liabilities are reported on a contract-by-contract basis at the end of each reporting period in prepaid expenses and other assets (contract assets), and accrued expenses and other liabilities (contract liabilities). These assets and liabilities and changes in these assets and liabilities were not material as of and for the nine months ended September 30, 2019.Trex Commercial pays sales commissions that are directly attributable to identifiable contracts to certain of its employees. If the amortization period of the commission is one year or less , then the Company recognizes the commission expense as incurred. Otherwise, the Company capitalizes the commission and amortizes it on a straight-line basis over the life of the contract. Trex Commercial does not grant contractual product return rights to customers other than pursuant to its assurance product warranty. All shipping and handling fees invoiced to the customer are included in net sales and the related costs are included in cost of sales.For the three months and nine months ended September The tables also include a reconciliation of the respective disaggregated net sales with the Company’s reportable segments (in thousands):

The Company recognizes stock-based compensation expense ratably over the period from the grant date to the earlier of: (1) the vesting date of the award, or (2) the date the grantee is eligible to retire without forfeiting the award. For performance-based restricted stock and performance-based restricted stock units, expense is recognized ratably over the performance and vesting period of each tranche based on management’s judgment of the ultimate award that is likely to be paid out based on the achievement of the predetermined performance measures.

| Income Tax Disclosure [Abstract] | |||
| Income Taxes |
The Company’s effective tax rate for the nine months ended September 30, 2019 and 2018 was 23.5% and 24.1%, respectively, which resulted in expense of $33.5 million and $34.7 million, respectively. The decrease of 0.6% in the effective tax rate was primarily due to a current year increase in excess tax benefits from the exercise of share-based payments. During the nine months ended September 30, 2019 and 2018, the Company realized $3.3 million and $2.3 million, respectively, of excess tax benefits from stock-based awards and recorded a corresponding benefit to income tax expense. The Company analyzes its deferred tax assets each reporting period, considering all available positive and negative evidence in determining the expected realization of those deferred tax assets. As of September 30, 2019, the Company maintains a valuation allowance of $3.0 million against deferred tax assets primarily related to state tax credits it estimates will expire before they are realized. The Company operates in multiple tax jurisdictions and, in the normal course of business, its tax returns are subject to examination by various taxing authorities. Such examinations may result in future assessments by these taxing authorities, and the Company accrues a liability when it believes that it is more likely than not that benefits of tax positions will not be realized. The Company believes that adequate provisions have been made for all tax returns subject to examination. As of September 30, 2019, for certain tax jurisdictions tax years 2015 through 2018 remain subject to examination. The Company’s returns filed with the state of Oregon for the tax years 2015 through 2017 are currently under examination. No material adjustments are expected as a result of the audit. Sales made to foreign distributors are not taxable in any foreign jurisdiction as the Company does not have a taxable presence in any foreign jurisdiction

| Segment Information |
The Company operates in two reportable segments:
The Company’s reportable segments have been determined in accordance with its internal management structure, which is organized based on residential and commercial sales activities. The Company evaluates performance of each segment primarily based on net sales and earnings before interest, taxes, depreciation and amortization (EBITDA). The Company uses net sales to assess performance and allocate resources as this measure represents the amount of business the segment engaged in during a given period of time, is an indicator of market growth and acceptance of segment products, and represents the segment’s customers’ spending habits along with the amount of product the segment sells relative to its competitors. The Company uses EBITDA to assess performance and allocate resources because it believes that EBITDA facilitates performance comparison between the segments by eliminating interest, taxes, and depreciation and amortization charges to income. The below segment data for the three and nine months ended September 30, 2019 and 2018 includes data for Trex Residential and Trex Commercial (in thousands): Segment Data:

| Seasonality |
The operating results for Trex Residential have historically varied from quarter to quarter. Seasonal, erratic or prolonged adverse weather conditions in certain geographic regions reduce the level of home improvement and construction activity and can shift demand for its products to a later period. As part of its normal business practice and consistent with industry practice, Trex Residential has historically offered incentive programs to its distributors and dealers to build inventory levels before the start of the prime deck-building season in order to ensure adequate availability of its product to meet anticipated seasonal consumer demand. The seasonal effects are often offset by the positive effect of the incentive programs. The operating results for Trex Commercial have not historically varied from quarter to quarter as a result of seasonality. However, they are driven by the timing of individual projects, which may vary each quarterly period. |

| Commitments and Contingencies |
Product Warranty The Company warrants that its decking and residential railing products will be free from material defects in workmanship and materials for warranty periods ranging from 10 years to 25 years, depending on the product and its use. If there is a breach of such warranties, the Company has an obligation either to replace the defective product or refund the purchase price. The Company continues to receive and settle claims for products manufactured at its Nevada facility prior to 2007 that exhibit surface flaking and maintains a warranty reserve to provide for the settlement of these claims. Estimating the warranty reserve for surface flaking claims requires management to estimate (1) the number of claims to be settled with payment and (2) the average cost to settle each claim. To estimate the number of claims to be settled with payment, the Company utilizes actuarial techniques to quantify both the expected number of claims to be received and the percentage of those claims that will ultimately require payment (collectively, elements). Estimates for these elements are quantified using a range of assumptions derived from claim count history and the identification of factors influencing the claim counts. The cost per claim varies due to a number of factors, including the size of affected decks, the availability and type of replacement material used, the cost of production of replacement material and the method of claim settlement. The Company monitors surface flaking claims activity each quarter for indications that its estimates require revision. Typically, a majority of surface flaking claims received in a year are received during the summer outdoor season, which spans the second and third quarters. It has been the Company’s practice to utilize the actuarial techniques discussed above during the third quarter, after a significant portion of all claims has been received for the fiscal year and variances to annual claims expectations are more meaningful. The number of incoming claims received in the nine months ended September 30, 2019 was lower than the Company’s expectations and lower than the number of claims received in the nine months ended September 30, 2018, continuing the historical year-over-year decline in incoming claims. Average settlement cost per claim experienced in the nine months ended September 30, 2019 was higher than the Company’s expectations and higher than the average settlement cost per claim experienced in the nine months ended September 30, 2018 The Company believes its reserve at September 30, 2019 is sufficient to cover future surface flaking obligations and no adjustments were required in the current quarter. The Company’s analysis is based on currently known facts and a number of assumptions, as discussed above, and current expectations. Projecting future events such as the number of claims to be received, the number of claims that will require payment and the average cost of claims could cause actual warranty liabilities to be higher or lower than those projected, which could materially affect the Company’s financial condition, results of operations or cash flows. The Company estimates that the annual number of claims received will continue to decline over time and that the average cost per claim will increase slightly, primarily due to inflation. If the level of claims received or average cost per claim differs materially from expectations, it could result in additional increases or decreases to the warranty reserve and a decrease or increase in earnings and cash flows in future periods. The Company estimates that a 10% change in the expected number of remaining claims to be settled with payment or the expected cost to settle claims may result in approximately a $2.0 million change in the surface flaking warranty reserve. The following is a reconciliation of the Company’s residential product warranty reserve (in thousands):
Legal Matters The Company has lawsuits, as well as other claims, pending against it which are ordinary routine litigation and claims incidental to the business. Management has evaluated the merits of these lawsuits and claims, and believes that their ultimate resolution will not have a material effect on the Company’s consolidated financial condition, results of operations, liquidity or competitive position. |
