There was a fairly lengthy thread on Nyloboard a while back that kept popping up again every few months.

Initially there was a big concern since many plastics have a high expansion rate, and at the time Nyloboard did not publish the data on this. Eventually they DID publish it, and it actually seems to have very little expansion at all... less than most woods actually, and is a better match to steel and aluminum from an expansion standpoint than the original plywood floor.

I was doing my first ever restoration so I had to learn as I went along with it. I decided from the beginning I was not going to do a full monte and I was not going to gut the trailer.

I took the bathroom out and drilled holes through the cross member (It already had holes for my bit to go through. I snapped a line and cut the floor in the middle of the cross member. So I would have room for a cut piece to fit. I then took a cross piece of garage door track and welded it on the cross member of the trailer for extra room for the new floor piece to sit on. I bolted the new Nyloboard floor on that piece. I had a piece of thin flat steel I was doing anything with and laid / attached to the black tank box right where the pieced of Nyloboard was going to sit. There was not going to be any sag plus keep the two cut pieces together. Honestly everything has worked for years and no complaints.

I think it came out great not knowing what I was doing. Check out these few links which shows the nyloboard and how I did it. Hey if it messes up I will just fix it.

you can see on the last link I have a wood but plate. I changed that out with the 4' wide sheet of steel. I made that decision after I realized the black tank would not fit.

Here's the current datasheet for it. Oh, and it's now called nylosheet
http://www.nyloboard.com/Portals/20/...%205-11%20.pdf

ASTM E84: Class C for the G2 nylosheet
ATSM E84: Class B Smoke for the G4 nylosheet.

Not that I have the slightest idea what that means.

Nyloboard alternatives

Heya Chris, you have an interesting alternative available that is manufactured pretty close to you, in Mississauga, Polyboard. They recycle plastics from industry (probably cutoffs from moulded door and dash panels, think Oshawa), comes in grey and white, plus it is 'green'. I do believe that is what I will use when we do the floor on Bubbles. We may have to install a couple of angle iron cross member supports but that will be a small price to pay for NO ROT.
This is the link: Polyboard | Renew Resources
I will use the grey and if it looks ok I may even forego putting anything on the floor except for a few rugs, or maybe some vinyl plank.
Looks like you are enjoy your trip you traitor, have fun with your Mom. It is truly miserable here in Ottawa today.
Hoist one for all of us in the Great White North,
Cheers
Leonie

I am thinking something 4 ft long and 1 ft wide.

I don't have scraps that size but maybe others that have used it in the past do. If I recall correctly, one Forum member was doing the full floor replacement w/ nyloboard

I've looked at their brochure and based on that info I did not see the polyboard being used as a main building component as nyloboard is sometimes used in 3" or more thickness. This would be another place for a strength test between products. I'm 6'6" and 240 lbs and my nyloboard flexed less than a plywood sheet the same size/ thickness - very rigid stuff.

Leonie I just did a little research on polyboard. IMO it's not a viable alternative to Nyloboard. First it's 40% heavier than wood and secondly it has quite a large expansion rate. 1/4" over a 4x8 sheet. they recommend leavinga 1/4" gap between sheets and to expand the mounting holes to allow for this expansion/contraction.

Exclamation NYLOBOARD Installation or repair???

A lot of people are asking quesitons here, but noone has of yet asked the big questions that come to my mind. As a former Naval Aviation type, I have the following concerns:
  1. Is there a major cost difference between nyloboard and wood?
  2. Are there any special tools or procedures required for installation? Any special types of epoxies, sealants, caulks, etc.?
  3. Can Nyloboard be repaired if cracked or damaged, and if so; what is the procedure?
I have contacted the MFG directly to see if my questions can be answered. I will post the information or a link to any informational sites that are supplied by the MFG.

I called Nyloboard last week to get pricing. The minimum factory direct order is 20 sheets at $175 per sheet for 3/4" material. If you want to order less you go though a distributor, Piedmont Plastics. I've called Piedmont Plastics multiple times, both local and toll free and nobody answers the phone.

I called Nyloboard back and informed them that I live about 100 miles away and would be interested in 6 sheets or one sheet 22 feet long. I was told I would have to go through the distributor, Piedmont Plastics, and could pick up at factory. I then asked about blems/out of square sheets. The girl was going to check and call back. I left a message with her on Monday. May try back later this week.

I'm still working on holding tank installation, as soon as I get this completed looks like the floor will be 3/4" marine grade available locally at $75 per sheet.

I really like the Nyloboard product and NO ROT is very appealing, a solid piece floor would be REAL SEXY, but not at 2.3X the prices and a non-supportive distributor network.

If anybody has had better luck in 2012 I would love to hear your approach.

Maybe you should contact the Nyloboard marketing person and tell them that their dealer networks sucks and that they are loosing business. There are alot of products out there but they are not main stream yet and that makes them a semi black market item to Joe Airstream who wants a few sheets. You mean you want our super special semi secret Nylo board. Shus where did you here about it. You are not supposed to know about it. We will sell you some at a price and a free tube of lubricant of you choice. Aluminum composite is another option and expensive in small quanities. It is hard to beat wood eventhough it has issues.

Now we need a chart comparing the same properties to wood.

well from what i see you guys have it good, i will spend upwards of 500 for my 25' tradewind wood floor! so $75 a sheet for me seems quite reasonable but i will say the floor, although totally wrecked had been in my trailer for 40 years i have no problem putting wood in again as i am already 40 and i don't really care who does this next!! as it will definately not be me, saying that i have fond plyboard which they use on truck flooring which i am thinking has some pretty nsaty chemicals in it to stop it rotting which is where i'm going!
