Frequently asked questions

How long does it take to learn ICF construction? This overview takes about 45 minutes. The full Basic ICF Installer course goes deeper in roughly two hours.

Is ICF hard to build with? No — the block is lightweight (about 7 lbs each, replacing six cinder blocks) and interlocks tightly, so the learning curve is short. This course shows the whole process so you know what to expect.

What’s the difference between this and the Basic course? This is a condensed overview; the Basic ICF Installation course expands each topic with more lessons, images, videos, and quizzes.
