I would use the materials designed for engine compartments instead of what is being discussed - not only will it help reduce noise but is fire rated.
Reflectix is good for radiative and a little bit of conductive, but the closed cell foams are better at conductive as the chart I posted shows. When installed and sealed around the edges the convective is taken care of as well.
