• To increase the thermal mass

How are the ICF panels held together?

• Nails

• Adhesive

• Interlocking joints

• Screws

What is used to prevent the ICF forms from shifting during the concrete pour?

• Heavy weights

• Adhesive

• Snap ties

• Metal braces

How is the internal reinforcement of the ICF walls achieved?

• Using a mesh of steel

• Using horizontal steel bars

• Using both horizontal and vertical steel bars

• Using vertical steel bars

What is the method used to pour concrete into the ICFs?

• Using a conveyor belt
