Rigid Foam Board Insulation
Rigid foam board insulation is a high-performance solution ideal for projects that demand maximum thermal resistance with minimal thickness. At Therma Source, we offer multiple types, such as Extruded Polystyrene (XPS), which balances compressive strength and consistent insulation performance.
These boards are commonly used in exterior walls, foundation insulation, roofing systems, and under-slab applications, where durability, water resistance, and energy efficiency are essential. Available in various sizes and thicknesses, our rigid foam boards are sourced from trusted manufacturers to ensure reliable performance in Canadian climates.
