Re: Transmogrifie and Me

OK, laid the paper down and started to arrange the styro board and I'm thinking I'm going to be sorry down the road with this stuff. Put a board down because I'm thinking weight spread over space would be less on the styro. My toes that were off the board made dents in the styro. Thinking I'm going to have no insulation very shortly once this stuff mashes down. So I started doing something else with it and ended up walking on it and my footprints barely dented it. hmmm.. I'm oscillating between using this 1/2" R-Tech or taking it back (again) and getting the stuff that's denser and $5 a sheet more. It has an r-3.2 rating where the R-Tech half inch says 1.9. I'm sooooo confused. Wanted to get the plywood tomorrow. Borrowed the saws and everything.

Oh and I found the 51 cent bin at Home Depot yesterday. For the furring strips. Thanks Lorna.

Re: Transmogrifie and Me

Some here have laid 1/2" plywood directly over their foam insulation boards and report no (or not much) squashing of the insulation but I decided to lay down some 3/4" wood runners under the 3/4" plywood to keep the insul. boards un-squashed. Maybe I did more than I needed to but I thought it was time well spent.

Re: Transmogrifie and Me

You have to put plywood over the styrofoam and use furring strips as well. Lay out the furring strips, place styro between the furring strips, plywood on top of that.


We didn't go that route. Personal choice. You do need to insulate the floor. Lots of heat transfer in the flooring. Not to mention you need to insulate your tanks and piping from the heat and cold. The need to insulate piping & tanks is why we insulated from the outside. This way we only insulate the floor once.

Re: Transmogrifie and Me

The pink board is made to underlay. I think it's 15 psi max loading. I used 3/4" tongue 'n groove plywood over the 1" foam board. I'm sure you could use thinner osb or ply panels, but if it isn't tongue 'n groove the seams better lie on some batts. If they move you could squish the foam.

I like this, makes sense. And 3/4" wouldn't sag as much. I'll check out what they have for furring tomorrow. Thanks for the pic. Didn't want to go 1" really because I am only 5'2... anyone over 5'10 is already going to barely fit.

Re: Transmogrifie and Me

OKay.. gotta show my pics. I'm one beat mamma tonight..

The paper roll is holding down a curling plywood edge...
makeshift saw horses....

old shelf boards I used for 'walking on'.


I left the posts for the two front risers as I'm not sure what I want to do with that area yet. Think I want to keep them. Used the foam core board to make the fit, then I used it as a pattern to cut the plywood. So I have access to the bolts, or I'll cover them up or take them out all together. Thinking the one behind the drivers seat might save my rear someday from a wild piano breaking loose. Actually I was considering extending the one behind the driver's seat a bit and taking out the passenger side one and making the stairs come up through there.
Seam looks a little rough in this picture but I filled it in and it butted up fine.



Anyways, might not have been how 'someone else' would have done it but I decided this morning that I had to quit second guessing myself and 'git er done'. Someone commented about the potato chip effect.. and.. most definitely. I cut the boards too close, too tight, and I couldn't get it to 'bend' over the chair rail, so I had to cut the end off. In pasting it back together, I tried using these little hammer in staple things, look like butterfly bandages. Worthless. So I just duck taped the seam for now.

How do you 'fix' the chip effect and how do you hold your ply seams together since you can't screw or nail them down really. Even had the home depot pro desk wondering about that. One guy suggested this tar like tape that is about 6" wide. It was real expensive.

Had to buy more expensive plywood in the area where the trafficmaster flooring is going to be used, used the cheaper stuff on the sides where there wont be as much traffic and under where the carpet is going.

Anyway.. long day, have about the last 9 feet yet to plywood tomorrow.

Re: Transmogrifie and Me

The ability to screw down the floor panels was one of the big reasons I used the wood runners under the plywood panels. My linoleum flooring doesn't like floor movement so fastening it down was key.

Re: Transmogrifie and Me

That's why you use furring strips and you do the edges first, then the center (butt the wall side of the plywood to the wall, then lower towards the center of the bus). Thaat way you don't have to "clear" the chair rail.
