Cut and Cobble with Damaged ICF Blocks
The recent severe weather in the Midwest (I'm in central Illinois, climate zone 5A) left me with A LOT of damaged ICF blocks that were intended to be used for my foundation walls. Most of it is unusable (without significant bracing) due to the "lego nubs" being broken off or large chunks from the corners missing or one side of the block is broken but the other side is just fine. (The wind picked up the bundles of blocks, broke them up, and blew the blocks across a corn field...I'm still picking up little bits of EPS).
So now I'm trying to come up with some way of RE-USING the EPS instead of just trashing/recycling it. I had two ideas churning in my head and I read Martin's blog about "Cut and Cobble" so I feel inspired to get some advice and/or ideas from others.
I have two ideas on how to use it. Both involve "disassembling" the blocks into two pieces of 4' long by 16" high by 2.75" thick pieces of EPS.
1.) The attic is planned to be ~R-60 with DIY blown cellulose. My idea is prior to blowing the cellulose, I would cut and cobble the EPS foam between the joists. I'm thinking that I wouldn't have to worry about sealing the seams, tight/loose fits, expansion/contraction of wood. The 16"+ of cellulose and airtight ceiling would take care of all that.
2.) Use the pieces of EPS as additional sub-slab insulation. Again, I feel that this is an area where the installation doesn't need to be "perfect" in order to still be effective.
Thoughts and advice are GREATLY appreciated!!!
