I picked up the 32" insulated metal door today and hope to get it set this weekend. Also, I searched for cedar paneling but came up zilch. Most available spanish cedar is in small sizes for small projects (like humidors). I need 4x8 sheets and will probably have to settle for red cedar. It does not have quite the absorbtion capacity as spanish but will do just fine since there will be around 144 sq ft on the shelf-side wall alone. If anyone knows a source for large quantities of spanish cedar I would much appreciate the help. I found this site during some of my searches.

I'm making an extra effort to be sure this room is well sealed. I'm hoping that being well insulated and having so much glass adjoing the living space it will maintain a reasonable temperature without additional A/C in the summer months. If not, the humidifier will be battling the A/C which is of course de-humidifing.
