Comparing Polystyrenes: Looking at the differences between EPS and XPS


Insulation is a critical component to specify when designing a functional, cost-effective, and energy-efficient building. One method to insulate a building is by installing 50 to 152 mm (2 to 6 in.) of rigid foam insulation on the exterior side of the wall framing. Two of the most frequently installed types of rigid foam insulation are expanded and extruded polystyrene (EPS and XPS).
