Here's a more detailed breakdown:​

• Material:

  The foam blocks provide insulation while the concrete and steel provide strength and structural integrity. 

• Benefits:

  ICF construction offers numerous advantages, including: 

  • Energy Efficiency:  Excellent insulation properties lead to lower energy consumption for heating and cooling with R-values of greater than 20.

  • Durability:  The concrete core provides a strong and durable structure that can withstand various weather conditions and forces. The insulated forms protect the concrete from the elements.

  • Soundproofing:  ICF walls offer excellent sound insulation, creating quieter indoor environments. 

  • Fire Resistance:  ICFs provide passive fire protection, with some systems having fire ratings of 4+ hours.

  • Faster Construction:  ICFs can be faster to install than traditional methods, potentially reducing labor costs. 

  • Natural Vapor Barrier:  Water proof, mold proof, and rot proof from the inside out. 

  • Flexible - can be designed with 6" and 8" reinforced concrete.

• Cons:

  • ICFs cost 5-10% more than poured walls or CMU block, however the cost difference is quickly offset by 7-8 times higher R-values, the cost of waterproofing CMU/Poured walls, and the other advantages outlines above.​

• Construction:

  ICFs are stacked together like giant Lego bricks to form the exterior walls or foundation of a building. Construction is efficent and safe with no waste.
