Fact 10

The versatility of concrete can be seen in its application as a carrying medium for heating or cooling, whether this is via air or fluids.  The hollow cores in precast concrete floors can be used or pipes can be cast into slabs.  The concrete surface radiates very effectively, enables space to be used without the hindrance of radiators and protects the heating or cooling system within.
