Quinnlites in rising wall for timberframe

    Hi all, we are in the process of putting in foundations and floors for our timber frame house (1 1/2 storey, 280 m2). On the top course of the load bearing rising walls I have specified Quinnlite B5 aerated foundation blocks to help minimise heat transfer at the junction between the top of the rising wall and soleplate onto which the timber will be secured. Does anyone have any experience of attaching soleplates or timberframes to the quinnlites? Were there any issues in relation to fastening the timber to the Quinnlite? what type of fastening is recommended?.

    Also, could someone tell me if the B5 with a compressive strength of 5 N/mm2 is comparable to that of standard concrete blocks?

    I am just trying to ensure that while I may be benefiting from the enhanced thermal properties that the Quinnlite B5 offer, I don't fall foul of some structural issue now are in the future that I may not be aware of.

    Thanks in advance.

    you need to be advised by your structural engineer, i would invite the eng on site with rising wall and timber frame guys for that chat. you may also want to use that chat to formalise the floor junction air-tightness detail.. there are other 'stronger strength':) Quin blocks that still do the same job.
    the idea is the low therm conductivity material is used to continue the floor insulation to meet the wall insulation, so you may want to consider more than one row of blocks.
