Default Do Bridge rectifier blocks need to be isolated from chassis?

Newbie question:

I have these bridge rectifiers I am using in a f5 build:

VS-36MB100A Vishay Semiconductors | Mouser

Do they need to be isolated from the chassis w/a silpad or mica? I know the descrete diodes do. Do rectifier blocks need to isolated as well?

These packages are electrically insulated already. No need for pad or mica.

Typically they have an insulated base designed to be directly mounted to the chassis or a heatsink, I'd assume that to be the case with that model as well.

A little bit of heatsink compound would be helpful.
