What is Polyiso Insulation?

Polyiso (polyisocyanurate) insulation is a high-performance rigid foam board commonly used in both commercial and residential construction. Known for its excellent thermal resistance, it is manufactured as a closed-cell, continuous insulation solution, often faced with foil or fibreglass for added durability. Its lightweight structure and high R-value per inch make it one of the most efficient and trusted insulation materials on the market.
