minimising thermal bridging under sole plate on timber frame

PJMCKE

Hi,
I am looking for ideas to put towards my builder and engineer for reducing thermal bridging from the soleplate under the timberframe on a raft foundation. I am also hoping to use 200mm of EPS if all goes to plan (hoping the the quinnlite block has a thickness to accomodate 200eps and up to 100mm screed. I would like to hear of any experiences quinnlite or other. hope this makes sense to all reading.

Graaaaa

What sort of size is the soleplate? Does it reach up through your insulation to the screed? Maybe it is really so insignificant as not to get too obsessed?
Haven't used the quinnlite blocks, but from hearsay I believe that as with all lightweight concrete blocks, there can be problems fixing to them for hanging things.
Generally the rising wall is constructed with the cavity filled with concrete, or with two rows of blocks on flat laid side by side and bonded together. The detail for blocks on a raft shouldn't be so different, if I am understanding this part of your question correctly?

Hi, i recently got a quote form the above mentioned company for
the material for our foundations 63sqm @ €45/m2.
timber frame solution quoted.

can anyone tell me what it would cost to install?
is it specialised that you would need someone trained to install.
or can any builder do it??
