The Details for the Passive House - Rising Walls

Wall make-up :

365mm insulated block construction - 140mm inner leaf, 125mm rigid Xtratherm  insulation and 100mm external leaf

Thermal Calculations :

20mm Render (sand/cement)
100mm outer block
125mm Cavity with 120mm CT/PIR (5mm cavity unventilated Low E)
140mm inner block
13mm Plaster
 This gives U-value 0.15

Floor Make-up : 

Note - The radon barrier/DPM was taken below the sub-slab instead of above - both acceptable but positioned below the membrane is protected during the build and adds

a waterproof membrane to the sub-slab.
