Back when we were researching our “forever home”, we chose ICF construction for a number of reasons. It’s tough, energy efficient and should last a lifetime with minimal upkeep. In this post, I’ll discuss:
- what ICF construction is
- how it differs from conventional construction
- why we chose Insulated Concrete Forms
- how much energy is saved (for heating and cooling) by using ICF construction
- how an ICF home performs during emergencies
- ICF costs
- whether it’s suitable for the do-it-yourselfer
- what it’s like living in the house
- recommendations for potential ICF problem areas
Let’s get started!
What is ICF (Insulated Concrete Forms)?
ICF (Insulated Concrete Forms) are premade forms that fit together like legos or large interlocking blocks. The outside of the form is flat sheets of foam insulation. These sheets are connected with plastic framework. During construction, the ICF blocks are fitted together, laced with rebar, and filled with concrete. The forms are insulated on the inside and the outside, providing high level of wall insulation uncommon in standard home construction. Because the ICF blocks fit together virtually seamlessly, there is very little air infiltration, increasing the effective insulation value.
