I am getting ready to sheet the walls on my transit and have a Noobie question...
Do I need to attach lath strips to the bus frame first, or can I just screw my 1/4" luan panel directly to the frame?
I may keep the original pink insulation or replace it with rigid foam board (insulation value is adequate for my inteded useage).
Does the added air space with the use of lath strips add to insulation, or does it just help in locating attach points when the wall sheeting covers everything up?
Also, for those who have been there done that, what do you reccomend for self drilling machine screws or pre-drilling?
Trying to keep things simple....
Thanks,
Mike. |

Michael,
Don't know what kind of bus you have, but we furred our MC9 and installed sound board between the furring. Two reasons, first, Luan, attached directly to the skin would provide an irregular surface due to the projecting rivet heads. Second, we want both the extra insulation and sound deadening in the coach. In fact, we furred our rear "seat" about three inches, then used closed cell reflective insulation followed by sound board, then R-13 insulation. Can hardly hear the engine. The real test will come this summer, when we hit the hot weather.
We pre-drilled everything.

A good reason for firring, besides what is stated above, is that luan will warp and bow a great deal without being adequately span supported and backed, which is lacking on most buses that I am familiar with. Also, luan is insufficient to anchor anything else to and try to find that hidden framing of the bus at a later date. If u fir strip is used, you merely fill the created void w/more insulation. The more the better, as you will learn when u try to heat or cool that puppy. |

Furring also allows for switch boxes and wire runs

We screwed plywood directly to the ribs with self drilling screws. Half inch plywood on the walls to the top of the windows, quarter inch up from there. solid enough to mount the oak cupboards directly to the plywood. Still tight after 65,000 miles. Lots of ways to do it.

I have an RTSII Transit
In my case, I made wall modules of firring strips, spaced 12" apart. Insulation between the firring and attached 1/4" panel to the strips.
Where there might be attachments to the wall, an additional support was added.
This was a long thought out plan as well as the easiest way to make changes should it ever be needed. (NOT in my lifetime)
Just think that the 1/4 panel is somewhat supportive and spacing the firring 12" helps keep the bending out of the panel should someone push against it.
Just my thought
