John, The CoDeMo samples they send you are only about 2"x3", not much to evaluate as far as bendability.
Flexibility is a good point, but at the codemo.com site they list some of the numerous applications they've successfully used this stuff in, and it seems to include many places more demanding than Airstreams:
- saunas/steam rooms
- horse stall liners
- dance floors
- greenhouses
- outdoor furniture.

Pretty cool, and it won't absorb moisture or delaminate over time. If the price is reasonable, sign me up! Can't wait to hear more from JohnG and Malcom.

Not to put too fine a point on it, but those are 'suggested' applications, not actual successful applications. I looked at this stuff a while back. It would be great, but the modulus of elasticity indicated to me that I would need to add more support under the floor.

Perfectly legit clarification - my bad. If it begins to get too far away from the stiffiness of plywood, it will definitely have to be reevaluated. It wouldn't suit me at all, if it felt too spongey underfoot.

I think the only people that would consider CoDeMo are those doing a full floor replacement. If you have the shell off and the floor out, it wouldn't be difficult to add a few more crossmembers. I certainly don't want to discourage anyone, I would try it if I had more time and money.

Don,

Get a sample of this stuff sent to you. It surprised me.

I received the CoDeMo samples today and this stuff looks great. That is what I am going to section the back with. This stuff is really strong for its weight.

Now I have to find out where I have to go to get this stiuff. People around here never heard of it. If I have to order it I may just order a bundle cause I always have use for marine plywood and this is even better.

Thanks for putting me onto this stuff Malconium

John,
I did get a sample. Unfortunately it wasn't big enough to do any real bend testing, so my comments about adding more stiffeners was based entirely on their published modulus of elasticity numbers. It's hard for me to tell how stiff it is compared to plywood based on a sample only a few inches wide.
Anyway, I wish you great success! I applaud anyone who tries to find a better way to do something.
And a standing ovation if they are willing to share their ideas on the forums.

Don,

Actually I didn't remember that you had told me about the size of the samples in an earlier post. You have some good points because the size of the samples they sent are too small to effectively do any such test on. I wonder how they woiuld respond if a person asked them for a 2' x 2' at 3/4" sample. I would pay them if they wanted and then I could do a more informative test on the material. I think I will try to get a sample in that size before I just jump in and buy a bunch of this stuff.
I have not yet pulled up the floor in my bathroom. In fact I could go ahead and use the trailer for a little while before I ever have to worry about his since my frame seperation is only like 1/8" right now. So I won't be getting to the floor replacement until my work on the trailer reaches that point. In fact that will be one of the last projects on the old girl. So it being a little while I do have time to look into all the possibly products to use back there, but I have to say that this CoDeMo stuff does look real promising right now.
Got a few questions;
How far apart are the supports in the bathroom floor?
Are there any opens of more than 2 feet where support is void?
Also when you bolt this or any material to the frame dosen't it gain a type of support from the material it is bolted to? Or if pressure is applied to it between the supports will it bend down like a spongey floor and pull the supports themselves toward the center by any fraction?

One more thought, I started this thread with the idea that an aluminum floor would be superior because it will not rot and offers great support. The drawback was the additional weight the aluminum floor would have.
This CoDeMo material looks ok since it is only a few pounds heaver than the marine plywood would be so it works ok in that side of the coin, but if it is too flexible between the supports then it will be of no use.
I suppose someone could stiffen it with the use of angle or tubing, but again it is more weight, added cost, added work, and you have to ask yourself if it is really worth it. Who knows when all is said and done it may just be better to replace with the original material, marine plywood. I am just looking for that perfect material that won't require any maintenance and has no worry I guess.

John,
Sorry I can't help with the distance between crossmembers in a '75 31' Sovereign. My '59 Tradewind has 24" between, but I know some of the larger models with gray water tanks may have been longer. I don't even know if your model had a gray tank.
Another issue is the rigidity of the crossmembers in your model. Mine are solid, but I know the '75s had 'lightened' crossmembers. That might figure into your calculations.
I would call Codemco and see if they will send you a mill end ot trim piece for testing. I'm sure if you tell them what it's for they will give it to you, but you might need to pay the freight.

I plan on calling them to talk on Monday. I don't know what material will work out best, but I think this might be worth looking into. I hope they will be able to send me something that will give me a better idea for sure, plus maybe they can tell me where the closest dealer is to find this stuff.

Aluminum flooring

John G,

Malconium mentioned the aluminum-skinned, aluminum honey-combed sheets. If you want to contact Hexlite about these pieces you may find that a joint order is the only affordable way. They wouldn't ship fewer than seven carbon/nomex panels, but see if this has changed or is different for aluminum panels. Their stats are absolutely staggering--a Hexlite 230 0.50 inch panel that is .79lbs/sq. ft. A three inch wide by twenty inch long panel deflects a mere 0.15in when subjected to a 100lb. load. The Hexlite fiberglass/Nomex aramid panels are only 0.47lbs/sq ft and deflect only 0.04inches under the 100lb. load. Talk about STIFF. And these are not even the carbon fiber panels. Go for it! I'm all for replacing the floor once...even better to drop 57lbs. per panel every time you put one in.
As was said in the referenced thread, there is no water damage, burning potential or mold/mildew potential. My question was whether or not the aluminum panels had much of an R-value as I'm living in the frozen North...

Second thoughts

One of the things that may be most importand to the consideration of alternate flooring materials is the effect on flooring flex. There HAS to be a certain amount figured into the original flooring and the flexion has to go somewhere...I wonder if Andy at Inland RV has tried or repaired alternate flooring materials like aluminum, fiberglass or carbon/kevlar?

Any new information?

John,

Did you ever get any more information about the Codemo panels?

Almost perfect floor material...

Yesterday I found a plastic panel material that was in stock locally that was almost perfect for AS floor replacement. It is $57.20 per 3/4" x 4' x 8' sheet and it is virtually indestructable. The catch (and it is a big one) is that it is not stiff enough. I do not know how it compares to the CoDeMo panels as far as stiffness but it is sure floppy. When you let about 3' of a sheet of 3/4" plywood overhang the stack it basically sticks out straight. This stuff sags 6 to 12". Anyway you can take a look at the information about the product at the following web site:

www.newcityresources.com

The product is called Polyboard. Some of you reading this might have other uses for it besides for your AS floor. I can think of some other uses.

The material is not billed as being a structural material. The "General Installation" tab is the only place I could find where it talked about span distances in horizontal uses. It said there not to exeed 500~600 lbs load carrying weight. It also said that supports should be at a minimum of 12 centers to prevent deflection. Yes, It did say "12" too without any units mentioned. I assume that they meant inches but who knows. I do not understand enough about the structural details in their chart in the brochure I picked up to know what the deflection numbers mean. Maybe someone reading this could comment and perhaps compare it to plywood? The table said the following about the material:

dimensional stability - load deflection = 1.42 * 10-2 of span (the -2 is the negative power of)

I could envision adding additional support so that the maximum span was 10 or 12 inches if that would work. What I would be more concerned about though is the issue of how much structural support is the plywood actually providing (and needing to provide) to the bottom of the walls along the sides of the AS. My observation is that the plywood must be working with the outriggers to help support the bottom of the walls. That is likely to be one reason the original plywood was installed cross wise to the frame for more support to the ends of the outriggers. I guess I could envision doing something to beef up the support for the outriggers too. I just don't know how much extra support would be required and just where. Of course extra support adds to the cost of the solution along with the extra work involved.

If the support problem could be resolved this material seems like it would be really great.

Malcolm

Maybe perfect except for price...

At the same plastics supplier (GE Polymershaps) where I found the Polyboard I discussed other options. They carry King Plastics Starboard. It is pretty expensive but is not too bad otherwise. The weight is more than plywood which is a down side (about 50% more) but it is billed as a replacement for marine grade plywood in harsh outdoor marine applications. Sheet sizes that GE stocked were 54" x 96" for $215 per sheet. They did offer an alternative which sells for $145 per 4' x 8' sheet though. This stuff is supposedly pretty much the same as Starboard except that it does not have UV enhibitors added (which accounts for the higher cost of Starboard). The stuff is called "Sanalite" and is primarily offered as a cutting board material. I was told that the composition was virtually identical to Starboard except for the UV part. It is made mostly out of polyethelene. It could be a good choice if one could live with the extra weight and couled afford the $145 per sheet price. In my case I would need 7 sheets which adds up pretty fast.
