Carlisle Companies is a leading supplier of building envelope products and solutions designed to improve energy efficiency and sustainability in commercial and residential buildings. The company operates two main segments: Carlisle Construction Materials (CCM), which manufactures single-ply roofing membranes (EPDM, TPO, PVC), polyiso insulation, and engineered metal roofing and wall systems for commercial and institutional buildings; and Carlisle Weatherproofing Technologies (CWT), which produces waterproofing, moisture protection, air/vapor barriers, sealants, roof coatings, spray foam systems, and specialized insulation products. The company sells primarily to non-residential construction markets through distributors and serves both commercial and residential end-markets across the United States and internationally, with the majority of its revenues derived from commercial roofing and building envelope systems supplied to large distributor customers. Carlisle generates revenue through direct product sales and extended warranty contracts on roofing and weatherproofing systems.
