I am going to build a compartment, much like a chest freezer that will
incorporate a dorm fridge. The compartment will be made of styrofoam or the
blue insulating panels, and be to maintain a fermenting temperature of 75
degrees inside for beer fermentation. I need to join some sheets of
styrofoam or the blue insulated foam together.

Which glue would be best, and won't dissolve the insulation? Or maybe get
some of the wide foil refrigeration tape?

White or yellow glues work great on styrofoam, and yellow glues are
usually fairly water resistant as well.

Spray glues will usually dissolve styrofoam because solvents are added
to make glues and paints sprayable, but dissolving the styrofoam may
not necessarily be bad when it comes to gluing it. Contact cement,
except the water-based type, will dissolve styrofoam. Epoxy glue will
not dissolve it. Blue foam is usually styrofoam, just not the bead
type, and it insulates better and doesn't absorb water as much.
