Kamco's Exterior Wall Insulation category provides contractors with high-performance insulation solutions designed to improve energy efficiency, moisture control, and overall building envelope performance. At Kamco Supply Corp of Boston, we supply contractor-grade exterior wall insulation products specified for commercial, multifamily, and residential construction throughout New England.

This category includes rigid insulation options such as polyisocyanurate (PolyIso), extruded polystyrene (XPS), and expanded polystyrene (EPS), commonly used as continuous insulation in modern exterior wall assemblies. Exterior wall insulation plays a critical role in reducing thermal bridging, improving R-values, and supporting airtight, code-compliant building envelopes. Contractors rely on these materials for consistent performance, dimensional stability, and compatibility with air barriers, weather barriers, and cladding systems.

Whether you're working on new construction or exterior retrofits, Kamco's exterior wall insulation solutions help meet evolving energy codes while maintaining efficient installation workflows. These products are engineered to perform in harsh Northeast climates, including cold temperatures and variable moisture conditions.
