What are insulated concrete forms (ICFs) typically made of?

1. Constructed using polystyrene or a similar insulating product.

2. Ineffective for uses other than foundations.

3. Strictly used for insulating value.

4. Proven ineffective in northern climates.

5. Composed of traditional concrete materials.

6. Utilized primarily for commercial edifices.

The correct answer is: Constructed using polystyrene or a similar insulating product.

Insulated concrete forms (ICFs) are typically made of materials like polystyrene or other similar insulating products. These forms consist of interconnected foam boards or interlocking, hollow-core foam insulation blocks that are stacked and filled with concrete to form the structure of a building. The use of polystyrene in ICFs provides excellent insulation properties, making buildings more energy-efficient and reducing heating and cooling costs. This choice is the correct answer because it accurately describes the typical construction material used in insulated concrete forms. Options B, C, D, E, and F are incorrect as they either provide irrelevant information about ICFs or present false statements about their composition and purpose.
