Inside the ICF

Posted by Helmut Forren on Nov 28 in Foundation | 0 comments

All that white stuff you’ve seen is ICF, or Insulating Concrete Forms.  This stuff is great.  It’s expanded polystyrene forms, connected with steel webbing.  You stack them like Lego(tm) blocks, with reinforcing steel, then pour in concrete.  The forms do NOT get removed, but remain as insulation.  The steel webbing embedded in the forms provides connction points for applying drywall on the inside or siding on the outside, directly to the forms.  There’s no additional sheathing or house wrap required.  It’s all-inclusive.  (Below we can see the reinforcing steel inside, while Tim cuts a form with a hot knife… part of the regular assembly process.)
