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
