Spend the extra $ get an ICF home.

[–] 2 pts

Hi.

Do you know much about concrete as a material used to build homes? I wanted to know WHY people use insulated concrete instead of just plain concrete.

Everywhere I look everyone talks about the benefits of the ICF "system" meaning they focus on insulation but no one ever talks about how ICF compares to a home made of just plain concrete.

Do you know enough about the topic? What are the downsides to building a plain concrete home?

I'm by no means an expert, but the thing with concrete is that it's a liquid when you pour it so you you have to build a form for it to hold the shape you want while it cures.

Rather than expensive, metal forms painstakingly arranged and then disassembled, foam is dirt cheap and they're manufactured to fit together modularly like legos. So you essentially build a house out of foam legos and then fill the hollow parts with concrete. There's no need to remove the foam.

I think they just out drywall right over the foam, probably after some moisture proofing layer to prevent condensation.

I spent a few days researching it a few years ago, so that's about all I know and I could even be mistaken lol

Icf makes plumbing and wiring easy as well.foam is not only an insulator but a fire retardant to a degree. There is no need to run conduit or drill holes through studs. Just use a hot knife to cut a channel in the foam, lay in your pipe or wire and sheet it.

Exactly. I expect houses will get build with better materials now, less house fires etc. No one in europe builds their houses out of sticks.
