New Bus

Hello fellow skoolies!!

I have an 89 international 77 passenger bus I bought a year ago. Obviously i am converting it, and plan to live in it full time with a partner and two kids. I would like the potential to actually go north and play in the snow being that I am organic farming the rest of the year. The bus has factory insulation in the roof and walls. It seems the layers go...outside skin , tar or tar paper, fiberglass insulation, inside skin...would it be ok to leave all that and insulate inside the bus? or should all that come out? I'm not too excited about all the screws. Also want to make sure I do not create un healthy indoor living conditions(mold). Finally, If I leave the factory insulation my understanding is that I would put the silver bubble wrap looking stuff :) next to the inside skin, followed by insulation and then vapor seal then siding...Any insight is greatly appreciated!!

Gut it floor to ceiling and the walls. The fiberglass batting is horrid, and reinsulate with foam- either board or spray. This will also interrupt the thermal breaks that allow your heat to escape in the winter, create moisture, and breed mold. The screws are easy. They should be combination Philips and square. A #2 square bit on an impact driver will pop them out in about 10-15 minutes, unless they're rusted in. Side panels are screwed and tack-welded under the windows, so they also have to come out as well so you can break the welds. Its a lot of work, but you'll get a healthier bus out of it.

Ok sorry, I found previous comments on this...seems like majority believe removing old insulation is best...I knew that ..the Closed cell, two part spray foam in a two pound density seems to be the recommended route for the roof and side walls...Is the spray foam stand alone..?? No silver bubble wrap stuff needed?? and no vapor seal (plastic)?? no layering?? Thanks!!

Yep, scrap the interior panels. Putting them back in place will defeat the purpose of replacing the insulation.

thx alot!!..im kinda dense....and just to clarify...I do not need to use bubble wrap or vapor barrier(plastic)?? just the board or spray foam(which i'm assuming already functions as the bubble wrap and vapor barrier(plastic)?

and also same idea on the floor?? My initial plan was to build a sub floor ...so in order of layer id have metal bus floor..silver bubble wrap..panel board insulation..vapor barrier..and then boxcar wood siding for my floor..?? Sorry if I'm being repetitive..I have been really confused by this from many people....Mostly I'm confused If I need the bubble wrap in any situation and the plastic "vapor barrier"..

subbed, I'm in a eerily similar situation to you.. organic farmer, family, new bus, have a lot of the same questions as you. good luck, stick with it and keep posting on the forum here so I can follow along ;)
