Significant Accounting Policies	NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements include all of our wholly-owned subsidiaries. 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”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”) have been 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 audited 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 10-K”), Our interim operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results to be expected in future operating quarters. 10-K Note 2 to the audited consolidated financial statements in our 2018 Form 10-K Recently Adopted Accounting Pronouncements Standard Adoption ASU 2016-02, Leases (Topic 842) This Accounting Standards Update (“ASU”) requires substantially all leases, with the exception of leases with a term of one year or less, to be recorded on the balance sheet as a lease liability measured as the present value of the future lease payments with a corresponding right-of-use Recently Issued Accounting Pronouncements Not Yet Adopted We are currently evaluating the impact of certain ASU’s on our Condensed Consolidated Financial Statements or Notes to Consolidated Financial Statements, which are described below: Standard Description Effective Date Effect on the financial statements ASU 2016-13, Financial Instruments-Credit Losses (Topic 326) This pronouncement and subsequently-issued amendments change the accounting for credit losses on available-for-sale Annual periods beginning after December 15, 2019, including interim periods therein. Early adoption is permitted. Upon adoption of this pronouncement, we expect the accounts receivable balance and the contract assets balance included in other current assets on our Condensed Consolidated Balance Sheets to be affected, with an offsetting amount recorded to retained earnings in the period of adoption. We are currently assessing the quantitative impact the adoption will have on our financial statements. ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment To address concerns over the cost and complexity of the two-step one-step Annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, including interim periods therein. Early adoption is permitted. We anticipate the adoption of this ASU will not have a material impact on our consolidated financial statements or disclosures. ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement This pronouncement amends Topic 820 to eliminate, add and modify certain disclosure requirements for fair value measurements. Annual periods beginning after December 15, 2019, including interim periods therein. Early adoption is permitted. We are currently evaluating the provisions of this ASU and the impact it will have on our disclosures.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	NOTE 3 - REVENUE RECOGNITION Our revenues are derived primarily through contracts with customers whereby we install insulation and other complementary building products and are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. We recognize revenue using the percentage-of-completion cost-to-cost point-in-time When the percentage-of-completion cost-to-cost cost-to-cost Our long-term contracts can be subject to modification to account for changes in contract specifications and requirements. We consider contract modifications to exist when the modification either creates new, or changes the existing, enforceable rights and obligations. Most of our contract modifications are for goods or services that are not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up Sales terms typically do not exceed 30 days for short-term contracts and typically do not exceed 60 days for long-term contracts with customers. All contracts are billed either contractually or as work is performed. Billing on our long-term contracts occurs primarily on a monthly basis throughout the contract period whereby we submit invoices for customer payment based on actual or estimated costs incurred during the billing period. On certain of our long-term contracts the customer may withhold payment on an invoice equal to a percentage of the invoice amount, which will be subsequently paid after satisfactory completion of each installation project. This amount is referred to as retainage and is common practice in the construction industry, as it allows for customers to ensure the quality of the service performed prior to full payment.

During the nine months ended September 30, 2019, we recognized $7.1 million of revenue that was included in the contract liability balance at December 31, 2018. We did no Remaining performance obligations represent the transaction price of contracts for which work has not been performed and excludes unexercised contract options and potential modifications. As of September 30, 2019, the aggregate amount of the transaction price allocated to remaining uncompleted contracts was $83.5 million. We expect to satisfy remaining performance obligations and recognize revenue on substantially all of these uncompleted contracts over the next 18 months. Practical Expedients and Exemptions We generally expense sales commissions and other incremental costs of obtaining a contract when incurred because the amortization period is usually one year or less. Sales commissions are recorded within selling expenses on the Condensed Consolidated Statements of Operations and Comprehensive Income. We do not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less.

Leases [Abstract]
Leases	NOTE 7 - LEASES On January 1, 2019, we adopted ASC 842, “Leases” which, among other changes, requires us to record liabilities classified as operating leases on our Condensed Consolidated Balance Sheets along with a corresponding right-of-use non-lease right-of-use Upon adoption of ASC 842, we recorded a $44.9 million increase in other assets, a $1.4 million decrease to other current assets, a $1.0 million decrease to other current liabilities and a $44.5 million increase to operating lease obligations. These adjustments are the result of assigning a right-of-use We determine if an arrangement is a lease at inception. Most of our operating leases do not provide an implicit rate so we use our incremental borrowing rate based on the information available at the commencement date to determine the present value of future payments. We lease various assets in the ordinary course of business as follows: warehouses to store our materials and perform staging activities for certain products we install; various office spaces for selling and administrative activities to support our business; certain manufacturing facilities to produce insulation materials; and certain vehicles and equipment to facilitate our operations, including, but not limited to, trucks, forklifts and office equipment. Leases with an initial term of 12 months or less are not recorded on the balance sheet as we recognize lease expense for these leases on a straight-line basis over the lease term. Most lease agreements include one or more renewal options, all of which are at our sole discretion. Generally, future renewal options that have not been executed as of the balance sheet date are excluded from right-of-use Lease Position as of September 30, 2019 The table below presents the lease-related assets and liabilities recorded on the Condensed Consolidated Balance Sheet: (in thousands) Classification As of September 30, Assets Non-Current Operating Operating lease right-of-use $ 42,553 Finance Property and equipment, net 7,691 Total lease assets $ 50,244 Liabilities Current Operating Current maturities of operating lease obligations $ 15,032 Financing Current maturities of finance lease obligations 3,133 Non-Current Operating Operating lease obligations 27,129 Financing Finance lease obligations 3,682 Total lease liabilities $ 48,976 Weighted-average remaining lease term Operating leases 3.8 years Finance leases 2.6 years Weighted-average discount rate (1) Operating leases 4.85 % Finance leases 4.75 % (1) Upon adoption of the new lease standard, discount rates used for existing leases were established at January 1, 2019.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 8 - 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. Assets Measured at Fair Value on a Nonrecurring Basis Certain assets, specifically other intangible and long-lived assets, are measured at fair value on a nonrecurring basis in periods subsequent to initial recognition. Assets measured at fair value on a nonrecurring basis as of September 30, 2019 and December 31, 2018 are categorized based on the lowest level of significant input to the valuation. The assets are measured at fair value when our impairment assessment indicates a carrying value for each of the assets in excess of the asset’s estimated fair value. Undiscounted cash flows, a Level 3 input, are utilized in determining estimated fair values. During each of the three and nine months ended September 30, 2019 and 2018, we did not record any impairments on these assets required to be measured at fair value on a nonrecurring basis. Estimated Fair Value of Financial Instruments Accounts receivable, accounts payable and accrued liabilities as of September 30, 2019 and December 31, 2018 approximate fair value due to the short-term maturities of these financial instruments. The carrying amounts of certain long-term debt, including the Term Loan and ABL Revolver as of September 30, 2019 and December 31, 2018, approximate fair value due to the variable rate nature of the agreements. The carrying amounts of our operating lease right-of-use Derivative financial instruments are measured at fair value based on observable market information and appropriate valuation methods. Contingent consideration liabilities arise from future earnout payments to the sellers associated with certain acquisitions and are based on predetermined calculations of certain future results. These future payments are estimated by considering various factors, including business risk and projections. The contingent consideration liabilities are measured at fair value by discounting estimated future payments to their net present value using the appropriate weighted average cost of capital (WACC). The fair values of financial assets and liabilities that are recorded at fair value in the Condensed Consolidated Balance Sheets and not described above were as follows (in thousands): As of September 30, 2019 As of December 31, 2018 Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Financial assets: Cash equivalents $ 107,535 $ 107,535 $ — $ — $ 69,807 $ 69,807 $ — $ — Derivative financial instruments — — — — 1,765 — 1,765 — Total financial assets $ 107,535 $ 107,535 $ — $ — $ 71,572 $ 69,807 $ 1,765 $ — Financial liabilities: Derivative financial instruments $ 11,207 $ — $ 11,207 $ — $ 2,275 $ — $ 2,275 $ — Contingent consideration 3,724 — — 3,724 5,098 — — 5,098 Total financial liabilities $ 14,931 $ — $ 11,207 $ 3,724 $ 7,373 $ — $ 2,275 $ 5,098 See Note 4, Investments, for more information on cash equivalents included in the table above. Also see Note 9, Derivatives and Hedging Activities, for more information on derivative financial instruments. The change in fair value of the contingent consideration (a Level 3 input) was as follows (in thousands): Contingent consideration liability - January 1, 2019 $ 5,098 Preliminary purchase price 2,275 Fair value adjustments (410 ) Accretion in value 434 Amounts paid to sellers (371 ) Amounts cancelled (3,302 ) Contingent consideration liability - September 30, 2019 $ 3,724 The accretion in value of contingent consideration liabilities is included within administrative expenses on the Condensed Consolidated Statements of Operations and Comprehensive Income. The carrying values and associated fair values of financial assets and liabilities that are not recorded at fair value in the Condensed Consolidated Balance Sheets and not described above include our Senior Notes and investments. To estimate fair values of these items, we utilized third-party quotes which are derived all or in part from model prices, external sources, market prices, or the third-party’s internal records.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	NOTE 9 - DERIVATIVES AND HEDGING ACTIVITIES Cash Flow Hedges of Interest Rate Risk Our purpose for using interest rate derivatives is to add stability to interest expense and to manage our exposure to interest rate movements. During the first nine months of 2019, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. To accomplish these objectives, we primarily use interest rate swaps as part of our interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. As of September 30, 2019, we had two interest rate swaps, each with an associated floor, with a total beginning notional of $200.0 million, one that amortizes quarterly to $95.3 million at a maturity date of May 31, 2022 and one that amortizes quarterly to $93.3 million at a maturity date of April 15, 2025. We also had a forward interest rate swap with an associated floor beginning May 31, 2022 with a beginning notional of $100.0 million that amortizes quarterly to $97.0 million at a maturity date of April 15, 2025. T substantially all non-current The changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in other comprehensive income, net of tax on the Condensed Consolidated Statements of Operations and Comprehensive Income and in accumulated other comprehensive income on the Condensed Consolidated Balance Sheets and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. We had no such changes during the nine months ended September 30, 2019 or 2018. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense, net as interest payments are made on our variable-rate debt. Over the next twelve months, we estimate that an additional $1.5 million will be reclassified as an increase to interest expense, net. Additionally, we do not use derivatives for trading or speculative purposes and we currently do not have any derivatives that are not designated as hedges. As of September 30, 2019, the Company has not posted any collateral related to these agreements.

These expenses are included in administrative expenses on the accompanying Condensed Consolidated Statements of Operations and Comprehensive Income. Share-Based Compensation Common Stock Awards We periodically grant shares of our common stock to our board of directors and our employees. During the nine months ended September 30, 2019 and 2018, we granted approximately eight thousand and five thousand shares of our common stock, respectively, under our Omnibus Incentive Plan to non-employee In addition, we granted approximately 0.1 million shares of our common stock under our 2014 Omnibus Incentive Plan to employees during the nine months ended September 30, 2019 and 2018. The shares granted during the nine months ended September 30, 2019 and 2018 vest in three equal installments (rounded to the nearest whole share) annually on April 20 through 2022. Share-based compensation expense associated with non-performance As of September 30, 2019, we had $5.9 million of unrecognized compensation expense related to these nonvested common stock awards issued to the board of directors and our employees. 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 1.9 years. Shares forfeited are returned as treasury shares and available for future issuances. See the table below for changes in shares and related weighted average fair market value per share. Employees – Performance-Based Stock Awards During the nine months ended September 30, 2019, we issued under our 2014 Omnibus Incentive Plan approximately 46 thousand shares of our common stock to certain officers, which vest in two equal installments on each of April 20, 2020 and April 20, 2021. In addition, during the nine months ended September 30, 2019, we established, and our Board of Directors approved, performance-based targets in connection with common stock awards to be issued to certain officers in 2020 contingent upon achievement of these targets. Share-based compensation expense associated with these performance-based awards and prior performance-based grants was $0.8 million and $2.3 million for the three and nine months ended September 30, 2019, respectively, and $0.6 million and $1.6 million for the three and nine months ended September 30, 2018, respectively. As of September 30, 2019, we had $4.2 million of unrecognized compensation expense related to nonvested performance-based common stock awards. This expense is subject to future adjustments for forfeitures and is expected to be recognized over the remaining weighted-average period of 1.8 years using the graded-vesting method. See the table below for changes in shares and related weighted average fair market value per share. Employees – Performance-Based Restricted Stock Units During 2018, we established, and our board of directors approved, performance-based restricted stock units in connection with common stock awards which were issued to certain employees during the nine months ended September 30, 2019 based upon achievement of a performance target. In addition, during the nine months ended September 30, 2019, we established, and our board of directors approved, performed-based restricted stock units in connection with common stock awards to be issued to certain employees in 2020 based upon achievement of a performance target. These units will be accounted for as equity-based awards that will be settled with a fixed number of common shares. We recorded $0.2 million and $0.5 million in compensation expense associated with these performance-based units during the three and nine months ended September 30, 2019, respectively, and $0.3 million and $1.5 million for the three and nine months ended September 30, 2018, respectively. As of September 30, 2019, we had $0.4 million of unrecognized compensation expense related to nonvested performance-based common stock units. 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 0.6 years. See the table below for changes in shares and related weighted average fair market value per share. Share-Based Compensation Summary During the nine months ended September 30, 2019 and 2018, our employees surrendered approximately 45 thousand and 41 thousand shares of our common stock, respectively, to satisfy tax withholding obligations arising in connection with the vesting of common stock awards issued under our 2014 Omnibus Incentive Plan. We recognized excess tax benefits of $0.3 million and $0.5 million for the nine months ended September 30, 2019 and 2018, respectively, within the income tax provision in the Condensed Consolidated Statements of Operations and Comprehensive Income.

Other Commitments and Contingencies From time to time, various claims and litigation are asserted or commenced against us principally arising from contractual 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. During the year ended December 31, 2018, we entered into an agreement with one of our suppliers to purchase a portion of the insulation materials we utilize across our business. This agreement is effective January 1, 2019 through December 31, 2021 with a purchase obligation of $16.4 million for 2019, $21.4 million for 2020 and $15.0 million for 2021. For the nine months ended September 30, 2019, we have satisfied $7.2 million of our purchase obligation under this agreement. Additionally, we entered into an agreement with a chemical supplier with a purchase obligation of $0.6 million in 2019. Actual purchases made under this agreement for the nine months ended September 30, 2019 was $0.4 million.

The goodwill recognized in conjunction with these business combinations represents the excess cost of the acquired entity over the net amount assigned to assets acquired and liabilities assumed. We expect to deduct approximately $9.6 million of goodwill for tax purposes as a result of 2019 acquisitions. Purchase Price Allocations The estimated fair values of the assets acquired and liabilities assumed for the acquisitions, as well as total purchase prices and cash paid, approximated the following (in thousands): As of September 30, 2019 As of September 30, 2018 1st State Expert Other Total CDG Other Total Estimated fair values: Accounts receivable $ — $ 1,796 $ 254 $ 2,050 $ 1,731 $ 3,229 $ 4,960 Inventories 291 723 338 1,352 514 1,027 1,541 Other current assets — — 3 3 28 879 907 Property and equipment 989 235 667 1,891 933 1,893 2,826 Intangibles 3,382 6,740 2,242 12,364 3,711 16,681 20,392 Goodwill 1,857 8,545 930 11,332 4,898 7,007 11,905 Other non-current — 161 13 174 36 19 55 Accounts payable and other current liabilities (39 ) (42 ) (23 ) (104 ) (438 ) (2,046 ) (2,484 ) Fair value of assets acquired and purchase price 6,480 18,158 4,424 29,062 11,413 28,689 40,102 Less seller obligations 1,355 1,993 974 4,322 1,973 3,447 5,420 Cash paid $ 5,125 $ 16,165 $ 3,450 $ 24,740 $ 9,440 $ 25,242 $ 34,682 Contingent consideration is included as “seller obligations” in the above table or within “fair value of assets acquired” if subsequently paid during the period presented. These contingent payments consist primarily of earnouts based on performance that are recorded at fair value at the time of acquisition, and/or non-complete Further adjustments to the allocation for each acquisition still under its measurement period are expected as third-party and internal 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. As a result, insignificant adjustments to the fair value of assets acquired, and in some cases total purchase price, have been made to certain business combinations since the date of acquisition and future adjustments may be made through the end of each measurement period. Goodwill and intangibles per the above table do not agree to the total gross increases of these assets as shown in Note 5, Goodwill and Intangibles, during each of the three months ended September 30, 2019 and 2018 due to minor adjustments to goodwill for the allocation of certain acquisitions still under measurement as well as other immaterial intangible assets added during the ordinary course of business.

Earnings Per Share [Abstract]
Income Per Common Share	NOTE 16 - INCOME PER COMMON SHARE Basic net income per common share is calculated by dividing net income by the weighted average shares outstanding during the period, without consideration for common stock equivalents. Diluted net income per common share is calculated by adjusting weighted average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury stock method. Potential common stock is included in the diluted income per common share calculation when dilutive. The dilutive effect of outstanding restricted stock awards after application of the treasury stock method was 92 thousand and 98 thousand shares for the three and nine months ended September 30, 2019, respectively, and 84 thousand and 138 thousand shares for the three and nine months ended September 30, 2018, respectively.
