Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	NOTE 1 – ORGANIZATION Installed Building Products, Inc. (“IBP”), a Delaware corporation formed on October 28, 2011, and its subsidiaries (collectively referred to as the “Company” and “we”, “us” and “our”), primarily install insulation, garage doors, rain gutters, shower doors, closet shelving and mirrors, and other products for residential and commercial builders located in the continental United States. IBP operates in over 100 locations within the continental United States and its corporate office is located in Columbus, Ohio. We have one operating segment and a single reportable segment. Substantially all of our sales come from service-based installation of various products in the residential new construction, repair and remodel and commercial construction end markets. Each of our branches has the capacity to serve all of our end markets. The following table sets forth the percentage of our net revenue by end market: Three and six months ended June 30, June 30, Existing and new residential construction 89 % 89 % Commercial construction 11 11 100 % 100 % 2014 Initial Public Offering (“IPO”) On February 10, 2014, in anticipation of our IPO, we executed a 19.5-for-one stock split of our common stock, which consisted of 1,129,944 issued and outstanding shares immediately prior to the stock split. The effect of the stock split on outstanding shares and earnings per share has been retroactively applied to all periods presented. Following the split we had 22,033,901 stock-split adjusted shares of common stock issued and outstanding. On February 19, 2014, we completed an IPO of our common stock, which resulted in the sale of 8,567,500 shares. We received total proceeds from the IPO of $87,645, after deducting underwriter discounts and commissions of $6,597, based on a public offering price of $11.00 per share. We used $75,735 of the proceeds from our IPO to redeem our Redeemable Preferred Stock and $11,910 to pay down our revolving credit facility. Our common stock is listed on The New York Stock Exchange under the symbol “IBP.” See Note 6, Stockholders’ Equity, for further information. 2014 Secondary Public Offering On June 17, 2014, we completed a secondary offering of an aggregate of 9,314,196 shares of our common stock at a public offering price of $12.50 per share. The total offering size reflects 8,100,000 shares of common stock offered on behalf of certain selling stockholders (the “Selling Stockholders”) and 1,214,196 shares that were offered and sold by us pursuant to the exercise of the underwriters’ option to purchase additional shares. We did not receive any proceeds from the sale of shares by the Selling Stockholders. However, we received $14,418, after deducting underwriting discounts but before estimated offering expenses, from the exercise of the underwriters’ option to purchase additional shares. A registration statement relating to these securities was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on June 11, 2014.

Accounting Policies [Abstract]
Significant Accounting Policies	NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Principles of Consolidation The accompanying condensed consolidated financial statements include all of our wholly owned subsidiaries and majority owned subsidiaries. The non-controlling interest relating to majority owned subsidiaries is not significant for presentation. All intercompany accounts and transactions have been eliminated. The information furnished in the condensed consolidated financial statements includes normal recurring adjustments and reflects all adjustments which are, in the opinion of management, necessary for a fair presentation of the results of operations and statements of financial position for the interim periods presented. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. We believe that the disclosures are adequate to prevent the information presented from being misleading when read in conjunction with our fiscal 2014 consolidated financial statements and the notes thereto included in Part II, Item 8. Financial Statements and Supplementary Data, of our Annual Report on Form 10-K as filed with the SEC on March 13, 2015. The December 31, 2014 condensed consolidated balance sheet data was derived from the audited financial statements but does not include all disclosures required by U.S. GAAP. Unless otherwise indicated, all amounts are in thousands except share and per share amounts. Our interim operating results for the three and six months ended June 30, 2015 are not necessarily indicative of the results to be expected in future operating quarters. See Item 1A. Risk Factors, in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, for additional information regarding risk factors that may impact our results. Note 2 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 describes the significant accounting policies and estimates used in preparation of the consolidated financial statements. There have been no changes to our significant accounting policies or estimates during the three or six months ended June 30, 2015, other than implementing our share-based compensation policy during the six months ended June 30, 2015. Use of Estimates Preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include the allowance for doubtful accounts, valuation allowance on deferred tax assets, intangible assets and other long-lived assets, share-based compensation, reserves for general liability, workers’ compensation, and medical insurance. Management believes the accounting estimates are appropriate and reasonably determined; however, due to the inherent uncertainties in making these estimates, actual amounts could differ from such estimates. Advertising Costs Advertising costs are expensed as incurred. Advertising expense was approximately $570 and $1,009 for the three and six months ended June 30, 2015, respectively, and approximately $397 and $740 for the three and six months ended June 30, 2014, respectively, and is included in selling expense on the Condensed Consolidated Statements of Operations. Share-Based Compensation Our share-based compensation program is designed to attract and retain employees while also aligning employees’ interests with the interests of our stockholders. Restricted stock awards are periodically granted to certain employees, officers, and non-employee members of our Board of Directors under the stockholder-approved 2014 Omnibus Incentive Plan. The awards are deemed to be equity-based with a service condition and do not contain a market condition. Fair value of the awards to employees and officers is measured at the grant date and amortized to expense over the vesting period of the awards using the straight-line attribution method for all service-based awards with a graded vesting feature. This fair value is reduced by assumed forfeitures and adjusted for actual forfeitures until vesting. Employees and officers are subject to tax at the vesting date based on the market price of the shares on that date, or on the grant date if an election is made. The future income tax benefit associated with these awards is recorded over the vesting period. In the event dividends are ultimately declared and paid, a forfeiture rate for the unvested restricted shares would be applied. Recently Issued Accounting Pronouncements Not Yet Adopted In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 sets forth a new revenue recognition model that requires identifying the contract(s) with a customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations and recognizing the revenue upon satisfaction of performance obligations. In July 2015, the FASB voted to defer the application of the provisions of this standard for public companies until annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. We are still evaluating whether this ASU will have a material impact on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, “Interest – Imputation of Interest.” The amendments in this update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. For public business entities, the amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. We are still evaluating whether this ASU will have a material impact on our consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330).” The amendments in this update require an entity to measure inventory within the scope of this update at the lower of cost and net realizable value. For public business entities, the amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. We are still evaluating whether this ASU will have a material impact on our consolidated financial statements.

Debt Disclosure [Abstract]
Long-Term Debt	NOTE 4 – LONG-TERM DEBT Debt consists of the following: June 30, December 31, Term Loan as amended due April 30, 2020 $ 49,375 $ 24,688 Delayed Draw Term Loan 15,000 — Vehicle and equipment notes 8,968 1,346 Various notes payable, maturing through March 2025; payable in various monthly installments, including interest rates ranging from 0.0% to 10.0% 4,382 822 77,725 26,856 Less: current maturities (4,827 ) (1,786 ) Long-term debt, less current maturities $ 72,898 $ 25,070 On April 28, 2015, we amended our Credit Agreement (the “Amended Credit Agreement”) with a bank group for an aggregate commitment of $200,000. The Amended Credit Agreement provides for a Revolving Line of Credit (the “LOC”) with a maximum limit of $100,000, a term loan (the “Term Loan”) in the amount of $50,000, a delayed draw term loan (the “DDTL”) of $50,000 and an uncommitted accordion feature in the amount of $25,000, which may be drawn as a revolving balance or a term loan, if drawn. The Amended Credit Agreement has a maturity date of April 30, 2020 (the “Maturity Date”) and is secured by all of our assets except those subject to capital leases and master equipment and vehicle arrangements. There were no outstanding balances on our LOC at either December 31, 2014 or June 30, 2015. Our subsidiaries guarantee this debt. The LOC, Term Loan and DDTL bear interest at either 1) the Eurodollar rate (“LIBOR”) or 2) the Base Rate (which approximates Prime Rate), plus a margin based on the type of rate applied and the value (represented as a ratio) of our total debt to earnings. In addition, a commitment fee on the unused portion of these instruments is due quarterly. The fee ranges from 20.0 to 30.0 basis points for the entire term of the agreement and the rate is determined based on our leverage ratio. The Term Loan requires quarterly principal payments of $625 starting on June 30, 2015, with the quarterly payment amount increasing to $938 from June 30, 2017 through March 31, 2019, and further increasing to $1,250 from June 30, 2019 through March 31, 2020. The DDTL also requires principal payments beginning in the third quarter of 2016. The payments are determined as a percentage of the balance drawn on April 27, 2016 and continue through the second quarter of 2020. Any outstanding principal balances on the Term Loan and DDTL are due on the Maturity Date. The Amended Credit Agreement contains financial covenants requiring us to maintain 1) a leverage ratio of debt to earnings, as adjusted for certain items and as defined by the agreement, of no greater than 3.50 to 1.00 and 2) a fixed charge coverage ratio, as adjusted for certain items, of no less than 1.10 to 1.00. The Amended Credit Agreement also contains various restrictive non-financial covenants and a provision that, upon an event of default (as defined by the agreement), amounts outstanding under the LOC, Term Loan, and any outstanding DDTL would bear interest at the rate as determined above plus 2%. Vehicle and Equipment Notes In October 2014 and February 2015, we entered into a Master Loan and Security Agreement (“Master Loan Agreement”) and a Master Equipment Lease Agreement (“Master Equipment Agreement”), respectively, with various lenders to provide financing for the purpose of purchasing or leasing vehicles and equipment used in the normal course of business. Vehicles and equipment purchased or leased under these agreements serve as collateral for each note subject to each financing arrangement. Each financing arrangement under these agreements constitutes a separate note and obligation. Regular payments are due under each note for a period of 60 consecutive months after the incurrence of the obligation. The specific terms of each note are based on specific criteria, including the type of vehicle or equipment, the length of the term of the note, and the market interest rates at the time. There is no termination date of either agreement. The total aggregate balance under these agreements was $8,968 as of June 30, 2015.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 5 – FAIR VALUE MEASUREMENTS Fair Values Fair value is the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The standard establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Accounts receivable, accounts payable, and accrued liabilities as of June 30, 2015 and December 31, 2014 approximate fair value due to the short-term maturities of these financial instruments. The carrying amounts of the long-term debt, including the Term Loan, DDTL and LOC, approximate fair value as of June 30, 2015 and December 31, 2014 due to the short term maturities of the underlying variable rate LIBOR agreements. The carrying amounts of the obligations associated with our capital leases approximate fair value as of June 30, 2015 and December 31, 2014 because the associated assets generate sufficient cash to settle the obligations. All debt classifications represent Level 2 fair value measurements. Assets and Liabilities Measured at Fair Value on a Recurring Basis In many cases, a valuation technique used to measure fair value includes inputs from multiple levels of the fair value hierarchy. The lowest level of significant input determines the placement of the entire fair value measurement in the hierarchy. During the periods presented, there were no transfers between fair value hierarchical levels. Our Redeemable Preferred Stock was redeemed in February 2014 with proceeds from our IPO, eliminating the associated put option. In addition, the redeemable feature of our Redeemable Common Stock was terminated upon the IPO. See Note 1, Organization, “2014 Initial Public Offering,” for further information. As such, corresponding fair values are zero as of June 30, 2015 and December 31, 2014. The following is a general description of the valuation methodologies used for liabilities and mezzanine equity (which includes redeemable preferred and common stock) items measured at fair value during fiscal year 2014: Put option – Redeemable Preferred Stock – We identified a certain embedded feature in the Redeemable Preferred Stock that was required to be bifurcated and accounted for as a derivative. The identified put option allowed Redeemable Preferred stockholders to put their shares upon a change in control. The estimated fair value of the put option on Redeemable Preferred Stock was determined using our estimates of the probability of a change in control during each period the option was outstanding in combination with the accreted fair value of the Redeemable Preferred Stock during the option period. Those resulting probabilities were then calculated at net present value for each period presented. Redeemable Common Stock – The estimated fair value of the redeemable feature of certain shares of our outstanding common stock was determined using a combination of discounted cash flows and market multiple approach modeling in order to mark the Redeemable Common Stock to market at each period end. Changes in the fair value of recurring fair value measurements using significant unobservable inputs (Level 3) for the six months ended June 30, 2014 were as follows (in thousands): Balance as of January 1, 2014 $ 81,500 Adjustments to fair value measurement impacting the Statement of Stockholders’ Deficit and Redeemable Instruments 8,357 Adjustments to fair value measurement impacting the Statement of Operations (490 ) Termination of Redemption Feature on common stock and put option (89,367 ) Balance as of June 30, 2014 $ — The unrealized gain related to the put option liabilities is recorded within other expense (income) on the Condensed Consolidated Statements of Operations for the six months ended June 30, 2014.

Equity [Abstract]
Stockholders' Equity	NOTE 6 – STOCKHOLDERS’ EQUITY In anticipation of our IPO, we amended our Certificate of Incorporation on February 10, 2014 to, among other things, authorize additional shares of common and preferred stock. On February 25, 2014, we further amended our Certificate of Incorporation to delete references to the Redeemable Preferred Stock, all of which was redeemed with proceeds from our IPO and subsequently retired and cancelled. As of June 30, 2015, we had 5,000,000 shares of preferred stock authorized with no shares issued or outstanding, 100,000,000 shares of common stock authorized, 31,982,888 shares of common stock issued and 31,366,328 shares of common stock outstanding, all with par value of $0.01, and 616,560 shares of treasury stock at cost. On March 13, 2015, we entered into a share repurchase agreement with Installed Building Systems, Inc. (“IBS”), a related party, for the purchase of 315,000 shares of our common stock for a purchase price of $6,057 (or $19.23 per share, which represented a 7.5% discount to the last reported price of our common stock on March 13, 2015) plus minor costs we incurred with respect to the transaction of $43, totaling $6,100. The effect of these treasury shares reducing the number of common shares outstanding is reflected in our earnings per share calculation for the six months ended June 30, 2015. For additional information on the related party relationship, see Note 9, Related Party Transactions.

Employee Benefits	NOTE 7 – EMPLOYEE BENEFITS Healthcare Our healthcare benefit expense (net of employee contributions) was approximately $3,113 and $1,983 for the three months ended June 30, 2015 and 2014, respectively, for all plans and $5,828 and $4,594 for the six months ended June 30, 2015 and 2014, respectively. An accrual for estimated healthcare claims incurred but not reported (“IBNR”) is included within accrued compensation on the Condensed Consolidated Balance Sheets and was $1,547 and $1,089 as of June 30, 2015 and December 31, 2014, respectively. Workers’ Compensation Workers’ compensation expense totaled $1,985 and $2,036 for the three months ended June 30, 2015 and 2014, respectively, and $4,050 and $3,620 for the six months ended June 30, 2015 and 2014, respectively. Workers’ compensation known claims and IBNR reserves included on the Condensed Consolidated Balance Sheets were as follows: June 30, December 31, Included in other current liabilities $ 3,282 $ 2,504 Included in other long-term liabilities 4,170 5,752 $ 7,452 $ 8,256 We also had an insurance receivable for claims that exceeded the stop loss limit included on the Condensed Consolidated Balance Sheets. That receivable offsets an equal liability included within the reserve amounts noted above and was as follows: June 30, December 31, 2015 2014 Included in other non-current assets $ 1,530 $ 2,286 Share-Based Compensation Directors In June 2015 and 2014, we granted 13,188 and 23,490 shares of restricted stock, respectively, at a price of $22.74 and $12.77 per share, respectively, (which represents market price on the grant dates) to non-employee members of our Board of Directors. Accordingly, for each of the six month periods ended June 30, 2015 and 2014, we recorded $300 in compensation expense related to these grants within administrative expenses on the Condensed Consolidated Statements of Operations. These shares effectively vested on the grant date since there is deemed to be no service period associated with these awards. The lack of a vesting or service period may not apply to any future share grants under our 2014 Omnibus Incentive Plan. Employees During the six months ended June 30, 2015, we granted 130,613 shares of restricted stock which vest 100% between January 7, 2016 and March 31, 2016 for non-executive employees and in three equal installments (rounded to the nearest whole share) on each of March 31, 2016, March 31, 2017 and March 31, 2018 for certain officers. We recorded $556 and $658 in compensation expense related to these grants within administrative expenses on the Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2015, respectively. No shares were awarded during the three and six months ended June 30, 2014, and, accordingly, no expense was incurred. Nonvested restricted stock as of December 31, 2014 and changes during the six months ended June 30, 2015 were as follows: Restricted Weighted Nonvested restricted stock at December 31, 2014 — $ — Granted 130,613 21.53 Vested — — Forfeited (1,560 ) 21.79 Nonvested restricted stock at June 30, 2015 129,053 $ 21.52 As of June 30, 2015, there was $2,032 of unrecognized compensation expense related to nonvested restricted stock. This expense is subject to future adjustments for forfeitures and is expected to be recognized on a straight-line basis over the remaining weighted-average period of 1.3 years. Shares forfeited are returned as treasury shares and available for future issuances. As of June 30, 2015, 2,834,269 shares of common stock were available for issuance under the 2014 Omnibus Incentive Plan.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 8 – INCOME TAXES Our provision for income taxes as a percentage of pretax earnings (“effective tax rate”) is based on a current estimate of the annual effective income tax rate adjusted to reflect the impact of discrete items. During the three and six months ended June 30, 2015, the effective tax rate was 36.4 percent and 38.0 percent, respectively. These rates were favorably impacted by deductions related to domestic production activities, offset by separate tax filing entities in a loss position for which a full valuation allowance will be accounted for against the losses, causing no tax benefit to be recognized on the losses. During the six months ended June 30, 2015, we increased our uncertain tax positions related to an acquisition that did not impact the effective tax rate.

Related Party Transactions [Abstract]
Related Party Transactions	NOTE 9 – RELATED PARTY TRANSACTIONS We sell installation services to other companies related through common or affiliated ownership. We also purchase services and materials and pay rent to companies with common or related ownership. We lease our headquarters and other facilities from certain related parties. See Note 10, Commitments and Contingencies, for future minimum lease payments to be paid to these related parties. For the three and six months ended June 30, 2015 and 2014, the amount of sales to common or related parties as well as the purchases from and rent expense paid to these common or related parties were as follows: Three months ended Six months ended 2015 2014 2015 2014 Sales $ 1,571 $ 1,133 $ 2,737 $ 2,308 Purchases 170 1,151 286 2,323 Rent 148 139 296 284 During the second quarter of 2014, we appointed a new member of our Board of Directors who is also the CEO of M/I Homes, Inc. (NYSE: MHO), one of our customers. As a result, we have included all sales to this customer in the above table. At June 30, 2015 and December 31, 2014, we had related party balances of $1,493 and $1,255, respectively, included in accounts receivable on our Condensed Consolidated Balance Sheets. These balances represent trade accounts receivable arising during normal course of business with various related parties. M/I Homes, Inc. accounted for $651 and $627 of these balances as of June 30, 2015 and December 31, 2014, respectively. As a result of our acquisition of TCI Contracting, LLC (“TCI”) in 2012, one of our existing suppliers became classified as a related party until a change in ownership of the supplier resulted in an end to such classification in August 2014. Purchases made from this supplier during the three and six months ended June 30, 2014 were $1,044 and $2,133, respectively, and are included in total related party purchases in the preceding table. On March 13, 2015, we entered into a share repurchase agreement with Installed Building Systems, Inc. (“IBS”) for the purchase of 315,000 shares of our common stock. Jeff Edwards, our Chief Executive Officer, has beneficial ownership in the shares of our common stock held by IBS. See Note 6, Stockholders’ Equity, for additional information. As of December 31, 2014, the Company maintained a receivable from IBP Holding Company, related to us through direct control by Jeff Edwards, in the amount of approximately $600. The receivable represented amounts owed to us for wages and related expenses paid by the Company during 2011 to former employees of IBP Holding Company and was included in other current assets on the Condensed Consolidated Balance Sheet as of December 31, 2014. During the six months ended June 30, 2015, we received the full remaining balance and accordingly, no such receivable exists as of June 30, 2015.

The amounts were as follows: June 30, December 31, Insurance receivable for claims under a fully insured policy $ 2,013 $ — Insurance receivable for claims that exceeded the stop loss limit 821 677 Total insurance receivables included in other non-current assets $ 2,834 $ 677 Leases We are obligated under capital leases covering vehicles and certain equipment. The vehicle and equipment leases generally have terms ranging from four to six years. Total gross assets relating to capital leases were $65,718 and $65,238 as of June 30, 2015 and December 31, 2014, respectively, and a total of $19,487 and $20,499 were fully depreciated as of June 30, 2015 and December 31, 2014, respectively. The net book value of assets under capital leases was $25,821 and $28,754 as of June 30, 2015 and December 31, 2014, respectively, net of accumulated depreciation of $39,897 and $36,484 as of June 30, 2015 and December 31, 2014, respectively. Amortization of assets held under capital leases is included within cost of sales on the Condensed Consolidated Statements of Operations. We also have several noncancellable operating leases, primarily for buildings, improvements, equipment, and certain vehicles. These leases generally contain renewal options for periods ranging from one to five years and require us to pay all executory costs such as property taxes, maintenance and insurance. In some instances, lease agreements exist with related parties. Future minimum lease payments under noncancellable operating leases (with initial or remaining lease terms in excess of one year) with related parties as of June 30, 2015 are as follows (amounts are as of the fiscal year ended): Remainder of 2015 $ 194 2016 377 2017 150 2018 83 2019 — Thereafter — Supply Contract Commitments As of June 30, 2015, we had two product supply contracts, one extending through December 31, 2015 and one extending through August 31, 2017. Our obligations for both contracts are based on quantity without a specific rate applied and therefore are not quantifiable. We expect our quantity purchases to exceed the minimum quantity commitments for all years covered by the contracts. Actual purchases made under the contracts for the three months ended June 30, 2015 and 2014 were $16,139 and $12,388, respectively, and $31,136 and $20,840 for the six months ended June 30, 2015 and 2014, respectively. Other Commitments and Contingencies From time to time, various claims and litigation are asserted or commenced against us principally arising from contractual and tort matters and personnel and employment disputes. In determining loss contingencies, management considers the likelihood of loss as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss is recorded when it is considered probable that such a liability has been incurred and when the amount of loss can be reasonably estimated. As litigation is subject to inherent uncertainties, we cannot be certain that we will prevail in these matters. However, we do not believe that the ultimate outcome of any pending matters will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Business Combinations

Business Combinations [Abstract]
Business Combinations	NOTE 11 – BUSINESS COMBINATIONS As part of our ongoing strategy to increase market share in certain markets, we completed three business combinations during the six months ended June 30, 2015 and one business combination during the six months ended June 30, 2014. The goodwill recognized in conjunction with these business combinations is a result of both purchase price multiples based on operating cash flows and expected synergies. At least a portion of the goodwill resulting from the 2015 acquisitions is expected to be deductible for tax purposes while the goodwill resulting from the March 24, 2014 acquisition is not expected to be deductible for tax purposes. 2015 On March 12, 2015, we acquired 100% of the stock and membership interests of nine different legal entities, collectively referred to as BDI Insulation (“BDI”). The purchase price consisted of cash of $30,680 and seller obligations of $5,723. Revenue and net income since the date of acquisition included in our Condensed Consolidated Statement of Operations for the three months ended June 30, 2015 were $10,008 and $760, respectively, and $12,129 and $1,047, respectively, for the six months ended June 30, 2015. On April 6, 2015, we acquired 100% of the common stock of C.Q. Insulation Inc. (“CQ”). The purchase price consisted of cash of $5,045 and seller obligations of $1,995. Revenue and net income since the date of acquisition included in our Condensed Consolidated Statement of Operations for the three and six months ended June 30, 2015 were $2,705 and $264, respectively. On June 1, 2015, we acquired substantially all of the assets of Layman Brothers Contracting (“Layman”). The purchase price consisted of cash of $9,025 and seller obligations of $674. Revenue and net income since the date of acquisition included in our Condensed Consolidated Statement of Operations for the three and six months ended June 30, 2015 were $1,217 and $105, respectively. 2014 On March 24, 2014, we acquired 100% of the common stock of U.S. Insulation Corp. (“U.S. Insulation”). The purchase price consisted of cash of $2,006 and seller obligations of $279. Revenue and net income since the date of acquisition included in our Condensed Consolidated Statement of Operations for the three and six months ended June 30, 2014 was $2,946 and $186, respectively. The estimated fair values of the assets acquired and liabilities assumed for the acquisitions approximated the following (amounts related to 2015 acquisitions are preliminary): 2015 2014 Cash $ 761 $ — Accounts receivable 7,464 1,122 Inventories 1,399 234 Note receivable 12 — Income taxes receivable 53 — Other current assets 244 120 Property and equipment, net 1,929 520 Intangibles, net 31,360 846 Goodwill 20,745 1,202 Other non-current assets 3,736 — Accounts payable and accrued expenses (5,783 ) (1,362 ) Deferred income tax liabilities (4,823 ) (397 ) Other long-term liabilities (3,955 ) — Total purchase price $ 53,142 $ 2,285 Seller obligations $ 8,392 $ 279 Cash paid 44,750 2,006 Total purchase price $ 53,142 $ 2,285 The provisional amounts for BDI originally reported in our Quarterly Report on Form 10-Q for the period ended March 31, 2015 have been adjusted to reflect the review and ongoing analysis of the fair value measurements. As a result of independent appraisal, we increased goodwill and our seller obligations by approximately $200 for an adjustment to the fair value of a working capital contingent liability. This adjustment increased our total purchase price for BDI as reflected within the above table. Further adjustments to the allocation for all acquisitions described above are expected as third-party valuations are finalized, certain tax aspects of the transaction are completed, and customary post-closing reviews are concluded during the measurement period attributable to each individual business combination. Included in other noncurrent assets in the above table as of each of the three and six months ended June 30, 2015 is an insurance receivable of $2,013 and an indemnification asset associated with the acquisition of BDI in the amount of $1,723. These assets offset equal liabilities included in other long-term liabilities in the above table, which represent additional insurance reserves and an uncertain tax position liability for which we may be liable. All amounts are measured at their acquisition-date fair value. Estimates of acquired intangible assets related to the acquisitions are as follows: 2015 2014 Acquired intangibles assets Estimated Weighted Estimated Weighted Customer relationships $ 20,300 8 $ 546 10 Trademarks and trade names 9,390 15 216 15 Covenants not-to-compete 1,670 5 84 5 Pro Forma Information The unaudited pro forma information for the combined results of the Company has been prepared as if the 2015 acquisitions had taken place on January 1, 2014 and all 2014 acquisitions had taken place on January 1, 2013.

Earnings Per Share [Abstract]
Income (Loss) Per Common Share	NOTE 12 –INCOME (LOSS) PER COMMON SHARE Basic net income (loss) per share is calculated by dividing net income (loss) attributable to common stockholders by the weighted average shares outstanding during the period, without consideration for common stock equivalents. Diluted net income (loss) per share is calculated by adjusting weighted average shares outstanding for the dilutive effect of common share equivalents outstanding for the period, determined using the treasury stock method. Potential common shares are included in the diluted income (loss) per share calculation when dilutive. Diluted income (loss) per share was as follows: For the three months For the six months ended June 30, ended June 30, 2015 2014 2015 2014 Net income (loss) attributable to common stockholders — basic and diluted $ 6,507 $ 2,307 $ 7,749 $ (17,217 ) Weighted average number of common shares outstanding 31,228,000 30,777,955 31,360,060 28,370,787 Dilutive effect of outstanding restricted stock awards after application of the Treasury Stock Method 21,050 — 11,156 — Diluted shares outstanding 31,249,050 30,777,955 31,371,216 28,370,787 Basic income (loss) per share attributable to common stockholders $ 0.21 $ 0.07 $ 0.25 $ (0.61 ) Diluted income (loss) per share attributable to common stockholders $ 0.21 $ 0.07 $ 0.25 $ (0.61 ) There were no common stock equivalents with a dilutive effect during the three and six months ended June 30, 2014.

Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying condensed consolidated financial statements include all of our wholly owned subsidiaries and majority owned subsidiaries. The non-controlling interest relating to majority owned subsidiaries is not significant for presentation. All intercompany accounts and transactions have been eliminated. The information furnished in the condensed consolidated financial statements includes normal recurring adjustments and reflects all adjustments which are, in the opinion of management, necessary for a fair presentation of the results of operations and statements of financial position for the interim periods presented. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. We believe that the disclosures are adequate to prevent the information presented from being misleading when read in conjunction with our fiscal 2014 consolidated financial statements and the notes thereto included in Part II, Item 8. Financial Statements and Supplementary Data, of our Annual Report on Form 10-K as filed with the SEC on March 13, 2015. The December 31, 2014 condensed consolidated balance sheet data was derived from the audited financial statements but does not include all disclosures required by U.S. GAAP. Unless otherwise indicated, all amounts are in thousands except share and per share amounts. Our interim operating results for the three and six months ended June 30, 2015 are not necessarily indicative of the results to be expected in future operating quarters. See Item 1A. Risk Factors, in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, for additional information regarding risk factors that may impact our results. Note 2 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 describes the significant accounting policies and estimates used in preparation of the consolidated financial statements. There have been no changes to our significant accounting policies or estimates during the three or six months ended June 30, 2015, other than implementing our share-based compensation policy during the six months ended June 30, 2015.
Use of Estimates	Use of Estimates Preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include the allowance for doubtful accounts, valuation allowance on deferred tax assets, intangible assets and other long-lived assets, share-based compensation, reserves for general liability, workers’ compensation, and medical insurance. Management believes the accounting estimates are appropriate and reasonably determined; however, due to the inherent uncertainties in making these estimates, actual amounts could differ from such estimates.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred. Advertising expense was approximately $570 and $1,009 for the three and six months ended June 30, 2015, respectively, and approximately $397 and $740 for the three and six months ended June 30, 2014, respectively, and is included in selling expense on the Condensed Consolidated Statements of Operations.
Share-Based Compensation	Share-Based Compensation Our share-based compensation program is designed to attract and retain employees while also aligning employees’ interests with the interests of our stockholders. Restricted stock awards are periodically granted to certain employees, officers, and non-employee members of our Board of Directors under the stockholder-approved 2014 Omnibus Incentive Plan. The awards are deemed to be equity-based with a service condition and do not contain a market condition. Fair value of the awards to employees and officers is measured at the grant date and amortized to expense over the vesting period of the awards using the straight-line attribution method for all service-based awards with a graded vesting feature. This fair value is reduced by assumed forfeitures and adjusted for actual forfeitures until vesting. Employees and officers are subject to tax at the vesting date based on the market price of the shares on that date, or on the grant date if an election is made. The future income tax benefit associated with these awards is recorded over the vesting period. In the event dividends are ultimately declared and paid, a forfeiture rate for the unvested restricted shares would be applied.
Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Issued Accounting Pronouncements Not Yet Adopted In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 sets forth a new revenue recognition model that requires identifying the contract(s) with a customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations and recognizing the revenue upon satisfaction of performance obligations. In July 2015, the FASB voted to defer the application of the provisions of this standard for public companies until annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. We are still evaluating whether this ASU will have a material impact on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, “Interest – Imputation of Interest.” The amendments in this update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. For public business entities, the amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. We are still evaluating whether this ASU will have a material impact on our consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330).” The amendments in this update require an entity to measure inventory within the scope of this update at the lower of cost and net realizable value. For public business entities, the amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. We are still evaluating whether this ASU will have a material impact on our consolidated financial statements.
