well, this will be my work space...eventually.
i do need to think seriously about how to keep it insulated and damp free.
tough when its only going to be a 'wiggly tin' roof.
You might want to look into the following:
- Rigid Foam Insulation, then cover with heavy duty plastic sheeting to seal out moisture. Not sure where you're located, but I suspect this would be the less expensive option.
- DIY Spray Foam Insulation Kit
Install some wood strips directly to the brick in order to attach a wall covering (peg board sheet, laminate sheet, or sheet rock/drywall for example).
There's also paints/coatings that are made for sealing brick and concrete walls & floors that might eliminate the need for plastic sheet.
