What U-value should these insulated foundations give
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/
@Thorfun , Here is a slightly out=of-date document which describes the methods for calculation of U-values for below ground walls and floors. Replace the Building Regs U-values and ignore the references to Elemental and Carbon Index methods
