furring strips ok, but what type of wood ?
I finally removed all rivets with a total of 6 40 grit sanding 5" discs attached to my angle grinder, this was faster that anything else I tried. Cleaned the inside and got rid of the old insulation and now the fun begins.
I was thinking on installing 1x1 furring strips to get more thickness for the injected insulation( total equal to a 2x4 would be ideal) that will come after and to be able to start attaching ceiling and walls but after looking around I have some questions :
Compression treated, fir, regular pine, oak ? what will be the best for moisture( in case of leak) and strength ?
Will the decision change if I installed on top of the existing ribs along side or across the ribs ?
Is it matter for adding strength to install them in a specific way ? ( I have read that the sheet metal originally installed on buses is part of the overall strength, that is my concern)
Metal studs could be a better option ?
An lastly, injected insulation to be installed in the winter ( pacific coast) is a bad idea ? moisture trap ?
