When we decided to build with ICF blocks, the first question we had - and many of you had - was how the heck to do run electrical in the walls?
For those of you new to the Momplex blog, the Momplex is actually built out of foam blocks. We used ARXX blocks, and the technical term is ICF short for Insulating Concrete Forms.
Was she really that little then?
The blocks are lightweight and hollow in the center.
You simply stack the blocks just like legos, one on top of the other, interlocking. Inside the blocks, you place rebar for reinforcement, and then pour concrete.
The concrete fills the void and creates the structure of the building, and acts as a vapor barrier. The foam stays on as the insulation. And the black webbing is designed to be used as a fastening strip for attaching siding and drywall. It really is a slick system and you end up with a super insulated wall.
But how to do electrical?
I've heard the term "hot knife" but haven't quite warmed up to the idea yet. Exactly how is this all going to work?
