Insulation keeps the heat in.
Radioactive decay generates the heat.

It wraps up in a snug coat and drinks hot cocoa.

OK, well the cocoa part is an exaggeration. But the snug coat isn't. The crust of the earth loses heat slowly to the atmosphere and the atmosphere loses heat slowly to outer space, but not much heat gets from the core of the earth to the atmosphere because the crust is a fairly good insulator.
