Hi all,    I'm after a little bit of help calculating the U-values for these proposed foundations using the Kore system.   this one is 200mm of EPS300 under the basement and up the walls:         and this is an example of what's under the rest of the house where there isn't a basement. this is a TSD designed Kore system with 300mm thick EPS which is very similar to the MBC passive slab so I would presume that this will yield a U-value of 0.105W/
