Comparing Polystyrenes: Looking at the differences between EPS and XPS

bigstock-Apartment119457272

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).

Metal composite panels with continuous insulation

5 IMG_0108

There are many different metal composite panel (MCP) assemblies with varying strengths. Traditionally, these claddings are simply fastened without insulation to the structural wall, through membrane water-resistive barriers (WRBs) and gypsum sheathing. However, some proprietary MCPs are fastened through continuous insulation (ci) to the structural wall. What advantages can this provide, not only with respect to thermal performance, but also durability and life safety?

Continuous insulation (ci) has been a component of exterior wall assemblies for almost a half-century in North America. By minimizing energy loss caused by thermal bridging and the risk of condensation caused by water vapor diffusion, exterior ci can improve building durability and benefit the environment. However, using rigid foam plastic comes with certain design considerations that must be reviewed early in the design process.

Continuous insulation (ci) has been a component of exterior wall assemblies for more than 40 years in North America and even longer in Europe. It has always been the smart way to design wall assemblies from the standpoint of energy conservation and water management. By minimizing energy loss caused by thermal bridging and the risk of condensation caused by water vapor diffusion, exterior ci can improve building durability and benefit the environment.
