Hello. I'm planning to build a small cabinet to store my power tools in during the winter since I only have a cold garage. The plan is to build a cabinet approximately 60x120cm out of plywood. I'll screw the boards onto 45 studs with insulation and then inner walls of plywood. I intend to have a small heater in there to maintain 10-15 degrees during winter. What I'm wondering is if a vapor barrier is needed in the walls and if ventilation is required? There won't be any significant moisture brought in with the tools. If I build it completely sealed, I should just be able to use a moisture absorber, right?
