Insulation manufacturers have devised numerous ways to improve the thermal performance of their products. Adding carbon or alumina particles to expanded polystyrene (EPS) increases infrared reflectance, and hence boosts R-value. For buildings that need heat stopped during the day and released at night, there are phase-change materials.
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.
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.
