The question was: "Does solid insulation makes the radiation weaker or
stop
it?"

it will not stop it, it might make it stronger or weaker depending on
the loss characteristics and what you measure as the strength.

And what with the "natural" insulations: the ice and the wet?

Sometimes are on your dipoles an ice or water.
They should melt/evaporate in the places where are picks of the voltage.
Is it observed?

Lodge observed the glows. So there should be the heating also.
Burn off an insulation needs more heat than melting/evaporating of
ice/water.
