$HTSC With rising number of building codes that promote energy-efficient structures, home builders and consumers are gradually moving toward building strategies that deliver performance and energy savings in the long run. One of the primary benefits of ICF is the continuous insulation on both sides of the wall.

By material type, polystyrene foam accounted for the largest market share in 2017 at around 90%. The segment is also expected to register the fastest CAGR through 2023. Among polystyrene foams, expanded polystyrene (EPS) is the most widely used foam in the ICF construction sector. Its superior insulation, lightweight nature, excellent resistance to moisture and pests, ease of handling, and processability make it an ideal ICF material. More than 85% of ICFs worldwide utilize molded EPS foam. The United States and Canada are the largest markets for EPS-based ICF.
