Insulated Concrete Forms and Gigacrete panels

Dallin Sumpter Feb. 21, 2019, 2:46 a.m.

I want to build a house to passive house standards and keep it to a relatively small budget. I stumbled upon ICFs and Gigacrete while researching building materials, but haven't seen a lot of passive houses built with these materials. Is there a reason why? They seem to be a pretty efficient method of building houses, can be air tight without a lot of additional work, dont have thermal bridges, and they tend to have a hard time catching fire (important where I live). I'm looking for an educated opinion because I am such a rookie.

I'm aslo planning to build a house, not necessarily up to passive house standards, but as green as economically possible. For the exterior wall I'm giving strong consideration to using Nexcem wall forms. You may find technical details here: https://nexcembuild.com/technicaldownloads-shtml/. Here is a video of a builder describing how he used Nexcem wall forms:  https://www.youtube.com/watch?v=T-Zqgb2_iy0. Note, Nexcem was recently known as Durisol, so you may find additional information online under that brand.
