Or beads poured in (as long as it’s not windy eh!). All I know about them is they are glued together in the horizontal but there appears to be no “glue” in the vertical joints, yes they are staggered but not air tight so draughty???

You would either plaster/render them on at least one side, or add a membrane.

There were no prices or stockists online in GB so a no-no over here.

Juwo SmartWall is essentially identical to Porotherm and sold here; last time I checked the prices it was around £100/m² for the blocks.

Those blocks look like Porotherm T7 MW which has a lambda value of 0.07 W/mK. Over 365mm this creates a U value of 0.19 W/m²K. The reciprocal of this is a metric R-value of 5.21. Coverting this to US units with 1 K⋅m²/W = 5.56 BTU/(h⋅°F⋅ft²) gives 29. A metric U of 0.18 gives US R value of 31.

Thank you Lili. Great information, much appreciated.

I'm too tired to think coherently tonight, but here are some pics:

Spent 3 days getting the 1st course right, training masons to work precisely.

 

 

 

 

 

The next layers went up so quickly I didn't get any early pictures

I spoke to the iriash importer today abd after a long conversation  it still seems thatTF is going to be cheaper 

basically the clay blocks with pearlite insulation is like and ICF build with out the wet concrete

 so yes for an old boy DIY then could be good  but not for my job

and the insulated blocks are not imported to UK at this time .although they were willing to get a price for them If I were keen

but after the conversation  seems not the right thing for me

 come in all sizes fro 100 -300mm and very long
