Kamco's PolyIso Insulation category provides contractors with high-performance rigid insulation solutions designed for exterior wall assemblies and continuous insulation applications. At Kamco Supply Corp of Boston, we supply contractor-grade polyisocyanurate (polyiso) insulation products trusted across commercial, multifamily, and residential construction in New England.

PolyIso insulation is valued for its high R-value per inch, making it an efficient choice where maximizing thermal performance within limited wall thickness is critical. These rigid foam boards are commonly used as continuous insulation in exterior wall systems to reduce thermal bridging and improve overall energy efficiency. Contractors rely on polyiso for its lightweight handling, consistent thickness, and compatibility with air barriers, weather barriers , and cladding systems.

This category supports modern building envelope designs that aim to meet or exceed current energy codes while maintaining constructability and long-term performance. PolyIso insulation is frequently specified for new construction and retrofit projects where improved insulation performance is required without significant changes to wall depth.

Kamco offers PolyIso insulation in jobsite-ready sizes and thicknesses to meet project specifications and performance goals. Browse this category to find dependable polyiso insulation solutions that help you deliver tighter, more energy-efficient exterior wall assemblies - backed by Kamco's reliable inventory, regional expertise, and contractor-focused service.
