How Insulation Board Types Influence Energy Efficiency in Building Design
Rigid Foam Insulation Boards
Rigid foam insulation boards are among the most popular choices due to their high R-value, which measures the board's resistance to heat flow. These boards are typically made from expanded polystyrene (EPS), extruded polystyrene (XPS), or polyisocyanurate (PIR). Each material offers distinct advantages. For instance, XPS boards are known for their moisture resistance, making them ideal for below-grade applications1. PIR boards, on the other hand, provide superior thermal resistance, which can be beneficial in colder climates2.
