I recently achieved the same insulation rating as ICF on a double brick home with cavity insulation. I would recommend doing something like blockwork filled with concrete and framing off that with insulation (if you're after strength), or installing double frames with insulation or brick veneer with insulation. There is way more embodied energy in getting the product to a good final finish than traditional framing or brick methods. I specialise in Green and Sustainable homes but to be honest I think ICF's are a little bit flawed. I had a carpenter armed with a blow torch and an electric planer spend about a week on one job just shaving walls back to get them Plumb and dead straight so I could get a perfect finish inside. Also the forms are foam and plastic, so naturally pouring in tonnes of concrete causes them to move around regardless of your bracing. (I have to make the concrete so wet when I pour it in that I have questions over it's strength). I have had to pump grout into a lot of window corners where the steel above the window opening has caused a clog in the concrete. Such as filling in cavities in the concrete because it was too dry a mix or the wall got clogged from all the steel or something like that. One of the biggest extra costs I have found is fixing the walls after they are poured.If you are cladding you need to have Mechanical fixings and can't rely on the foam. If you're going to Render the render doesn't always get the best adhesion. Finishing on the outside is a pain too.Finding the little clips within the ICF form to screw into can be a pain too. Just installing with glue/cement doesn't always work. Even power-points need be considered as over time if they are only attached to the drywall/foam they will pull off the wall.

If you want to install plantation shutters, baseboards, architraves, curtains, pretty much anything wall mounted, you have to plan ahead before you cover the walls with Drywall or similar.

For some wall mounted cabinets (like kitchens) you need to chase back the foam and install timber studs/plates. Liteform insulated concrete form provides a continuous insulation barrier that eliminates thermal bridging, air infiltration. Fixing to these walls afterwards can be a pain.* Obviously check all Labour and materials included, such as rebar. * Are they including the concrete pump as well? Has site access been considered? * Possibility of excess concrete loss due to blow-outs or foam failure Just beware the extra costs that aren't told to you by the suppliers. Best thing is to get quotes from suppliers/installers. I have built large homes with both Zego block and Eco-block ICFs. Material Costs Even though ICF structures are more durable, often with an expected lifespan of 200 years or more, the costs are also very economical.
