Detached garage in MA
I would like to insulate my detached wooden garage in MA, but I want to avoid condensation and mold. I accidentally stripped siding on two sides rather than strip the lead paint off (before I knew about Cobra IR paint stripper). Can I add exterior rigid insulation on just those two sides since I tore off siding there? Should I cover the other side fanfold insulation and vinyl siding to make it slightly warmer? I would use an electric heater for occasional heat. My option is to add a ridge vent and two gable vents and to create a small attic with drywall ceiling. Or should I avoid doing that? It has no soffit vents and wood block above wall seemingly blocking me from adding them. If I add a gable vent in the front, I will disrupt the water shedding layering of the original cedar shingles. I’ve been told to put mineral wool in the walls maybe covered with a membrane of some sort and ceiling or to put paper faced batt insulation and cover with drywall. I want it to be warmer so I can watch TV there. The concrete slab is from 1940. A cathedral ceiling would increase my storage space, but I have no soffit vents and am planning to add a ridge vent.
should I just add fanfold insulation on all three sides and cover with vinyl siding? Will it make it slightly warmer without creating condensation? What if I add a ridge vent – will it make it extra cold?
Or should I abandon the idea and let it air out and be here for another hundred years?
