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?
Heart surgery pending?

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.
There are construction adhesives made specifically for foam board.
Anything with a solvent base will NOT work and will eat huge holes
in the material. I would reinforce the joints with drilled and
glued wood dowels or all thread. I would remove the thin plastic
film from the face of the material where the glue joints occur if
you buy the type of foam that has it.
Keep the whole world singing . . .
OK for small stuff, but constructing panels it is not going to work well.
The glue will harden too fat at the start before you get to the end.
Regular hot glue will melt the foam and you get a recess where the glue bead
was. Styrene foam starts to melt at 180 degrees.
Epoxy won't dissolve the polystyrene and has the added advantage of
permitting structural reinforcement with fiberglass at corners and
joints. This would make your structure really robust, something you
need in a fermentation cabinet.
Considering your heart is failing, you should not be drinking alcohol.
So forget the whole project. Build some bird houses or lamps instead.
I do believe they sell a construction adhesive made particularly for
foam. Go to a building supply or hardware store where they have
knowledgable and educated adults working there, and tell them what you
need. Forget Home Depot. You wont get any help from that fat 18 year
old pimple faced kid with the cellphone glued to his ear, and the
baseball cap worn backwards. He only knows how to play video games
and text on his cellphone, and nothing more.
