No bus yet, but I've been on here and YouTube learning stuff all summer while recovering from double knee replacement surgery. BTW I go back to work on Monday 9/23 so this is the end of my lurking, for now.
If you want to know what I want to build look at my other post about a 4X4 Skoolie titled 4WD Conversion.
Time for a new thread about a new (unanswered so far using this forum and YouTube) question / problem... How do others insulate the ribs and other "impossible" areas on their bus?
I have concluded that closed cell foam insulation is the best option, weather sprayed or boards/rigid or a combo of both, professional sprayed or DIY. (There is literature and videos that support this, open cell holds water, and fiberglass has lower R value per inch and holds water, other batt materials like blue jeans?, etc.)
People talk about thermal bridging or you should create a thermal break. Dead air space (encapsulated) is/isn't an effective insulating method, and metal to metal is bad.
So has anyone insulated the ribs inside the walls, and other hidden or impossible areas? If so how did you do it?
Did you drill holes in the ribs or other areas and just shoot in cans of foam until it came out the hole? How large of a hole did you drill and how far apart? How well did this work?
If you did a roof raise or reskinned the outside of the bus did you insulate the ribs before the new skin went on? Or while roof is cut did you stick a really long spray wand inside the rib to insulate the roof rib before adding the additional support material? How did that work?
I have actually considered deconstructing the entire outer shell of the bus removing the windows and all the outer panels or skins, then removing all the factory insulation, coating the backside of the interior panels with something the spray foam wont stick to, then spraying the ribs and the back of the interior panels to have "completely" insulated bus walls, and then reskin the outside of the bus.
I know this sounds ridiculous, expensive and time consuming ( and a ton of rivets) BUT again I'm trying to find a solution to a brain fart of an idea that I had.
So what have you done, found, seen, links, videos, pictures.
READY, SET, GO
