More Insulation and Plywood

For the last few days and evenings ( essentially when I have spare time) I've been working on insulating the garage attached to the house.  This will give me a small space to do some extra work close to home  as well as help cut the heating cost for the house.  Our landlord has graciously agreed to pay for materials.  I also got a comission from him retro fitting some drawers in his kitchen cabinets of his trailor. I insulated the walls and then attached OSV/flake board to the walls and covered the seams with furring strips.  I can feel the difference already.
