Carlisle Companies (CSL)

Carlisle reports through two main segments: Carlisle Construction Materials and Carlisle Weatherproofing Technologies. Carlisle Construction Materials is the larger business and produces premium single-ply roofing membranes and related systems. Its offerings include EPDM, TPO, and PVC roofing membranes, polyiso insulation, adhesives, fasteners, edge metal, and other accessories that are sold as integrated roof systems. These products are widely used in low-slope commercial roofing, including both new construction and reroofing projects.

Carlisle Weatherproofing Technologies extends the company’s reach across the broader building envelope. It supplies waterproofing products, air and vapor barriers, moisture protection materials, sealants, and spray polyurethane foam systems. These solutions help manage water, air movement, and thermal performance in walls, foundations, and other parts of a structure.

The United States accounts for the majority of Carlisle’s revenue, reflecting the scale of the North American commercial construction and repair market. The company’s competitive position is supported by established brands, contractor relationships, distribution access, technical support, and warranty programs. Carlisle is especially associated with systems-based selling, where membranes, insulation, and accessories are specified together to meet performance requirements over a building’s life.
