Goodwill and Intangible Assets Disclosure [Abstract]
Impairment of Long-Lived Assets	Note E – Impairment of Long-Lived Assets During the third quarter of fiscal 2023, we determined that certain assets associated with a capital project at our Building Products facility in Jefferson, Ohio, were impaired. These assets were determined to have no alternative use and were written down to their estimated salvage value of approximately $70 resulting in an impairment charge of $484 during the three months ended February 28, 2023. Our Sustainable Energy Solutions business continues to operate in a challenging market, driven by continued weakness in overall economic conditions in Europe as well as slow adoption of hydrogen and CNG transportation applications. Management continues to focus on near term cost controls while making investments necessary to maintain its position as a global solutions provider with the scale and expertise to effectively serve the emerging sustainability economy worldwide. We believe the overall long-term outlook for the business is positive and project sufficient future cash flows to support the current carrying value of the business. However, it is at least reasonably possible that continued lower-than-expected volumes and financial results, or a decision to explore strategic alternatives, could change our determination that the assets are not impaired.
