I must be corn-fuzed. That looks like 2 different products with similar name. The fiber BOARDS in the video shed water due to their compressed nature. The BAT ROLL shown before that post would definatly trap moisture like any bat type insulation.

Stone wool insulation has been around a long time.

Chambers used it to insulate their ovens in the early 1900s. The stone wool in the Chambers waiting to go into our kitchen is in perfect condition, and the stove dates from around 1960.

The point about the product is not that it doesn't hold water, but that it isn't damaged by water. It will still hold a lot of moisture if it gets in there.

I wouldn't use it in a bus. My choice

This product is intended to be used OUTSIDE a house wrap...

Thanks Charlie! I'm so busy with work, babysitting and working outside in the bus (I'm not using heaters) that I'm either way too tired to come in and update or I literally fall asleep while reading the posts lol.

I have installed/used ROCKWOOL and ROXUL (different manufactures) and the fireproofing pillows that are pictured.
They are all good brands of products,
But must be used for there respective purpose.
Open cell as ROCK WOOL or ROXUL is very fire resistant but that is all it is designed to do.
It will soak up water like a sponge.
The pillows are designed are expensive because they are used to replace the fire stop putty or composite sheets installed that can't be removed to protect a cable tray or large opening through a wall.
The pillows stuff the openings and can be removed and stiffed back in for small wire replacement and decent size wire replacement .
The pillows are A lot of money to keep a fire from getting out/in .sealed properly and them being bagged will keep the water out of the insulation itself .
Unless those bricks of fire block insulation is packed tight enough that condensation can't get through those expensive blocks.
Sorry just got a work call I have to take?
Good luck
Have fun

They're the same, in general terms.
No one is saying to use it in place of foam. But it beats fiberglass, denim, cellulose, and all the other lame stuff.
For interior walls this stuff is BETTER than foam since it provides a nice fireproof barrier.

We need a good fire proof(at least resistant) insulation that's also water resistant...

The foam insulation in this bus does not burn. It's used in residential foundations and is harder than normal foam because it's designed to be buried. It was a beotch to trim this foam. Nearly two weeks.

I put a piece of this foam in wood fire in my back yard. It blackened but it didn't burn.

I'm with you Robin. Nobody will believe you:
LOOK AT YOUTUBE !!! IT BURNS !!!

Blue Bird factory sprayed my foam. I've welded on my ribs that are packed with spray foam and it singes, but doesn't ignite. I use a torch to solder wires and I tried to ignite the foam, with a butane torch. I have spray foam under my bus, above my muffler, around my battery box, and in my inner wheel-wells.

There are different spray foams- some are retardant. Very Retardant, it seems from my anecdotal experience.

But I'm all-for sponges and OSB.

Hi Tobeamiss,

I am a freelance journalist and future wannabe-skoolie dweller, and on both accounts, I'm looking for someone living in a skoolie in, around or close to New York to talk to.

Would you be willing to chat and maybe show me your bus?

Kind regards
Søren Steensig
