Abstract
Insulation is a critical component to specify when designing a functional, cost-effective, and energy-efficient building. Two of the most frequently installed types of rigid foam insulation are expanded (EPS) and extruded polystyrene (XPS). Both EPS and XPS serve the same basic function: to provide a means to manage the passage of heat in a building system. The primary responsibility of any insulating construction material is to provide positive thermal performance. However this is not the only factor to account when specifying a rigid foam insulation material. it is also critical to know how it will perform under several usage situations.
