doesnt work like that.

 

It works like this:

 

	Height (m)	Lambda (W/mK)	R-value (m²K/W)	U value
Thermoblock	0.065	0.05	1.30	0.77
Aircrete 7.3N	0.215	0.18	1.19	0.84

That was the way I calculated it all out also.

 

I used engineered brick on top of thermolite, good for fixing too. Our screed is 100mm concrete, so the thermolite block starts above the screed to insulation interface. So the no thermal bridges. All our internal walls are wood stud walls. We left an air gap either side of the acoustic insulation before the plasterboard. 

I calculated it that way too largely informed by one of your posts on one of my threads.
