We are have Beam and Block on A steel Beam and a timber frame building. The Frame provider has recommended blocks of 140mm sat on 10mm of mortar creating 150mm height. Then using 90mm of insulation and 60mm of screed.

 

We are not having underfloor heating, is this a sensible buildup of insulation and screed?

 

Are 140mm blocks available or would they need to be cut to size.

 

Looking for suggestions and information as to what others have done

 

 

surely your blocks must be same depth as the beams?

a picture of your suggested build of  floor please 

 this detail surely is noted on your plans

I wouldn’t think 90mm of insulation even gets to building regs does it.

Probably above the minimum threshold but will need to make up elsewhere and floor insulation is simple to fit, just chuck it down.  120mm Celotex would work.

You can get 150 x100X 440mm blocks.

Thanks for the replies so far, so if I need more than 90mm of insulation what is the next size of brick after 150mm.

 

Without underfloor heating what is the sensible thickness of Screed

Have you got a section drawing.
