Humber/Ontario Real Estate Course 3 Exam Practice

Which statement is true regarding insulated concrete forms (ICFs)?

1. Are primarily ineffective for uses other than foundations.

2. Are exclusively used for their insulating properties.

3. Are constructed using polystyrene or similar insulating materials.

4. Have shown ineffectiveness in colder climates.

5. Are generally considered outdated in modern construction.

6. Are only used in commercial building constructions.

The correct answer is: Are constructed using polystyrene or similar insulating materials.

Insulated Concrete Forms (ICFs) serve a unique role in modern construction by combining structural strength and energy efficiency. They are composed of expanded polystyrene foam or similar insulating materials that provide not only insulation but also the framework to support poured concrete. This combination allows for both energy-efficient building envelopes and strong structural integrity. ICFs are versatile and can be used in various applications beyond just foundations, including walls for residential and commercial buildings, which makes them relevant across multiple construction types. Their insulating properties provide significant advantages in energy savings, reducing heating and cooling costs for buildings, particularly in climates that experience both hot and cold temperatures. This understanding highlights the importance of the material properties and applications of ICFs in the construction industry, particularly their role in enhancing energy efficiency while providing robust structural support.
