Accounting Policies [Abstract]
Significant Accounting Policies	(2) Significant Accounting Policies Please refer to “Note 2. Summary of Basis of Presentation and Significant Accounting Policies,” to the Company's consolidated financial statements from the Annual Report for the discussion of the Company's significant accounting policies. Use of Estimates The preparation of the consolidated financial statements requires the Company to make a number of estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include allowances for doubtful accounts, sales returns and allowances, product warranty costs, inventory valuation, the carrying amount of property and equipment, right-of-use assets, lease liabilities, stock-based compensation, and deferred income taxes. The Company evaluates its estimates and assumptions on an on-going basis using historical experience and other factors, including current economic conditions, which are believed to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances warrant. Illiquid credit markets, volatile equity markets and declines in business investment can increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in these estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. Restricted Cash As of June 30, 2026, the Company had $1.7 million of restricted cash to support its outstanding letters of credit. Concentration of Credit Risk Financial instruments, which potentially expose the Company to concentrations of credit risk, consist principally of accounts receivable. The Company’s customers are primarily insulation distributors, insulation contractors, insulation fabricators and select energy and automotive end-users located throughout the world. The Company performs ongoing credit evaluations of its customers’ financial condition and generally requires no collateral to secure accounts receivable. The Company maintains an allowance for doubtful accounts based on its assessment of the collectability of accounts receivable. The Company reviews the allowance for doubtful accounts quarterly. During the six months ended June 30, 2026 and 2025, the Company recorded a decrease in the allowance for estimated customer uncollectible accounts receivable of less than $0.1 million and less than $0.1 million, respectively. For the six months ended June 30, 2026 and 2025, two customers represented 51% and 72% of total revenue, respectively. At June 30, 2026, the Company had one customer that accounted for 43% of accounts receivable. At December 31, 2025, the Company had two customers which accounted for 41% and 13% of accounts receivable, respectively. Revenue Recognition The Company recognizes revenue in accordance with Accounting Standards Codification 606, Revenue from Contracts with Customers (ASC 606). See Note (3) for further details. Recently Issued Accounting Standards From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (FASB) or other standard setting bodies. Recently issued standards typically do not require adoption until a future effective date. Prior to their effective date, the Company evaluates the pronouncements to determine the potential effects of adoption on its consolidated financial statements. Standards Implemented Since December 31, 2025 The Company has not implemented any accounting standards that had a material impact on its consolidated financial statements during the six months ended June 30, 2026. Standards to be Implemented In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (ASU 2024-03). ASU 2024-03 requires a public business entity to provide disaggregated disclosures of certain categories of expenses on an annual and interim basis including purchases of inventory, employee compensation, depreciation, and intangible asset amortization for each income statement line item that contains those expenses. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating ASU 2024-03 to determine its impact on the Company’s disclosures. Although there are several other new accounting pronouncements issued by the FASB, the Company does not believe any of these accounting pronouncements had or will have a material impact on its consolidated financial statements.
