impervious
Not letting through
Impervious means not allowing passage through—an impervious membrane blocks water, an impervious surface resists penetration.
The figurative sense dominates: impervious to criticism, impervious to charm, impervious to reason.
Someone impervious to something remains unaffected by it, whether by strength, indifference, or obliviousness.
