attaching polystyrene to plywood heatbox

[Justin Falon]

Any ideas of how to attach poloystyrene to the inside of my hot box?  I thought of using PL 300 or FRP panel adhesive.  Thanks.

Liquid Nail.  I used it to attach regular styrofoam to the inside of mine and it has held nicely.  I plan to replace the styrofoam with the foil backed insulation board so I just used small dabs of glue on the styrofoam and it has held good.

Double-sided tape?

If the polystyrene is the blue board, I wouldn't use it because it can melt with excess heat. I used foil backed foam board. The foil backing helps to reflect the heat also. I think I used liquid nails.   Pat

DryWall Screws? If ALL Else Fails, Use a DryWall Screw!!

Duct tape fixes everything, I would line the whole box with it.
