Carlisle Companies Incorporated is a leading manufacturer of building envelope products, operating primarily through two business segments: Carlisle Construction Materials (CCM) and Carlisle Weatherproofing Technologies (CWT). The CCM segment, which accounts for the majority of the company's revenue, focuses on premium single-ply roofing products, architectural metals, and related technologies for the commercial construction market. The CWT segment provides high-performance waterproofing, moisture protection products, protective roofing underlayments, and integrated air and vapor barriers. While the company generates the vast majority of its revenue in the United States, it also maintains manufacturing facilities and a sales presence in Europe and Canada. Historically a diversified industrial conglomerate, Carlisle has strategically divested its other businesses in recent years to become a pure-play building products company. Its competitive position is driven by mega-trends in energy efficiency, labor savings, and a strong reliance on the recurring commercial re-roofing cycle.
