                      Niobium-based superconducting RF (SRF) cavities are crucial
                      to achieve high accelerating fields and a low surface
                      resistance. Recent treatments aim to improve superconducting
                      properties by tailoring the interstitial atom concentration
                      or by depositing thin superconducting films. Yet, no
                      investigation of the thermal characteristics of those
                      surfaces after such treatments has been done, although this
                      is a crucial property to cool the induced RF losses away and
                      to maintain the superconducting state while high surface
                      magnetic fields are applied. In this contribution, a newly
                      developed experimental set up is described, which allowed
                      the first ever measurement of the thermal transmittance of
                      Mid-T heat treated and
                      Superconductor-Insulator-Superconductor (SIS) coated Niobium
                      samples. The results show that SIS samples perform the same
                      as standard Niobium and that Mid-T heat treated samples have
                      an improved thermal transmittance of 30\\%.},
