ICF Houses

    I have seen a few threads on here about ICF builds but they are all about the construction stage. I was wondering how people were getting on with them now after living in them for some time. I am looking a second hand house built in 2006 and was wondering are there any pitfalls to look out. Thanks

    Am in the process of planning a house and my intent is for ICF walls.

    Also interested to hear of any pitfalls that could maybe be addressed through up front design.

    Make you sure you retain independent designer to detail project at construction stage, as there will be junctions in IFC that won’t be considered in the standard details.

    The main suppliers of ICF blocks in Ireland have documented the detailing necessary for their products. I'll definitely be looking to an external consultant for construction drawings as suggested.

    Would it necessarily be recommended to use pre-made insulated roofing? One or two ICF companies offering this but it's quite specialist and I'm not convinced it's worth it. Also toying with idea of a passive style foundation system. Seems to be relatively straightforward.

    Just seen your post, one thing to watch out for in ICF is to be careful not to let the rebars drop directly onto your dpc ,either use the little plastic caps or run a length of 100 dia pvc pipe (cut in half so its a semi circular section) on top of the dpc and allow the bars to rest on the pipe. Just noticed your date of posting ,youve maybe built the house by now!
