Floor build up suggestions

Recommended Posts

I'm getting overloaded (emotionally, that is!). Please keep things simple..

 

On our stable conversion, the existing floor is 150mm concrete slab. 

The architect's technician  specified: T & G floating floor 

80mm celotex with 22mm 

DPM (linked to DPC/RIW/tanking

 

as minimum to get the BC regs passed and achieve u value of 0.22

 

However, now the builders are here it looks like we have 2 courses of bricks to Finished Floor level, which is 150mm. Not sure exactly how this discrepancy has happened...

I'm wondering how to improve the floor from that specified.

 

Will this small amount of insulation make UFH perform poorly ? (wanted it from a design and comfort aspect)

 

Would we be better off improving the floor insulation and having radiators?
