   Iron beams, joined I don't know how with brick and mortar. Probably they   
   form small arches or vaults that cross from beam to beam.   
      
   This house is old. Newer houses use preformed big hollow concrete or   
   ceramic tiles of special shape that matches the reinforced concrete   
   beams (almost I shape). And then they pour a layer of concrete over it.   
      
   However, the ceiling of my second floor is made of thick beams of   
   Canadian pine (imported). Beneath it there is a layer of canes joined   
   with some kind of string, and then they stick a layer of white plaster   
   to it, which is the part that I can see. Over it there is a fiber-glass   
   insulation layer (almost useless), and above it I had installed some   
   years back a modern layer of technical insulation, which is very good at   
   its job.   
      
   You can walk over there being careful to put your foot exactly where the   
   beams are. I can't do it.   
      
   And above that there are thinner beams forming a 30° slope, with   
   preformed industrial clay tiles on top.

   Cheers, Carlos.
