Hi, we have recently received planning permission for a new build and are in the process of deciding on the best approach for the build. We are looking for an energy efficient house (wall u-values of around 0.14) with a concrete first floor and have two options in mind:
1) Insulated concrete formwork (ICF) with SIPs roof.
2) Brick and block with CavityTherm wall insulation and a SIPS roof.
I wondered if anyone else had built using either of these approaches and if they would share their reasoning on why they went the way they did?
Thanks.
