Kamco's XPS Insulation category supplies contractors with durable rigid foam insulation designed for exterior wall and below-grade applications where strength and moisture resistance are critical. At Kamco Supply Corp of Boston, we provide contractor-grade extruded polystyrene (XPS) insulation products trusted on commercial, multifamily, and residential projects throughout New England.

XPS insulation delivers consistent R-value performance, high compressive strength, and excellent resistance to moisture absorption. These characteristics make it a common choice for exterior continuous insulation, foundation walls, perimeter insulation, and other demanding building envelope applications. Contractors rely on XPS boards for their dimensional stability, easy handling, and compatibility with air barriers, waterproofing systems, and cladding assemblies.

This category supports modern exterior wall designs that aim to reduce thermal bridging and improve overall energy efficiency while maintaining long-term durability. XPS insulation performs well in cold, wet conditions, making it especially suited for New England climates and below-grade installations.

Kamco stocks XPS insulation in jobsite-ready sizes and thicknesses to meet project specifications and code requirements. Browse this category to find dependable XPS insulation solutions that help you build stronger, more energy-efficient exterior wall systems - backed by Kamco's reliable inventory, regional expertise, and contractor-focused service.
