Consider rigid insulation such as SM or similar. It is available in various thicknesses including 1 1/2".
Cut to fit the voids, and for any gaps or going around wiring etc, use a bit of expandable spray foam.
Super light weight and it has an R value of R5 per inch, so R7.5 for your application. That's double what you'll get from regular batt insulation.
