Put up a TF ICF home and basement and have alot of left over foam that we had to cut off or had to trim off the edges. Is there any usefull place to place this foam to help with insulation that would save it from the landfill?  Would it really help by dumping it all in the attic ?

I had quite a few full length foam TF panels left after all the walls were poured. I used them to insulate a section of the garage floor. The nice thing about insulating the garage floor is that in summer, the floor doesn't reach dewpoint, so it doesn't sweat.

Great idea, i dont have a whole lot of full pieces, but LOTS of cut pieces, wouldnt hurt to put it all below the floor would it ?

If you don't want to spend the money to insulate the whole garage floor, you can simply insulate around the periphery where most of the heat loss will occur. Think along the lines of how a slab on grade foundation is insulated.

I think clark is thinking right here. The perimiter should be the focus. If you choose not to do that it can be recycled but you did pay for it so might as well use it. :)

I think once you take into account the foam crates that the foam was stacked on, ill have enough to do almost the entire garage using the pieces we had to trim down, left overs and cut ends and what not.

Composite ICFs use recycled EPS. And near me an EPS moulder grinds it and sells it as a pourable insulation, mostly for CMUs.

John, keep in mind that the foam pallets that the TF System panels were shipped on are made of a low density EPS.  Could experience some compression.  I'd use it around the periphery and be sure to tie the garage floor to the foundation (stem wall) with rebar dowels.

If ther are no recyclers in the area, post it on Craig's List as free - can be used for crafts or insulation.....and it will disapear

Central Florida now has an EPS recycler

I think there is misconceptions regarding plastic, including EPS. The landfills around here would rather get plastic than paper or cardboard. Which didn't make much sense to me but my uncle owns a roll-off construction dumpster company. I asked him why it says "no cardboard" on the side of dumpsters, he said the landfills don't want it. I am also told that is why shingle bundles come in plastic and no longer paper wrapping.

Shingles like groceries come in plastic because its cheaper and they don't fall apart when they get wet.

But there is a recycle market for EPS reqround is used in some OSB SIPs, also used for packing. None need to go to a landfill before we had a recycle source we would atvertise on Craig's list as free.
I have had teachers come and take for crafts and frugal DIY's re-use for insulation

in a cold climate, you can insulation to your footing

Personaly I would go with the floor insulation option. Insulating the ceilings with it will leave cracks and therefor compromising the seal created to eliminate heat loss. Also, most icf's have same if not higher density as floor insulation so greater settlement should not be of concern.
