[@HumbleRoad]

Go for it! 👍

[@joeblow1942]

SUBFLOOR: 1” x 1;8” aluminum joists are glued to high points on van floor rinb. Each glue point on van floor ribs was ground / sanded to bare metal so aluminum joists can bond to ribs. Spaces between each aluminum joist are filled with 1” polystyrene foam (Polyiso has better insulation qualities, is less messy to cut and lis more hydrophobic.) Foam sheets are glued to van floor ribs.. On top of that goes 1/2” plywood. This subfloor allows airflow between the van floor and underneath the subfloor.

[@SiepaczPustynny]

Did you consider screwing the aluminum joists to the floor instead of glueing them? In Sprinter you have some factory mounting points that could be used. Great work and great videos by the way :)

Sikaflex with the suitable primer should be more than strong enough without removing the paint - with all the problems of potential rust that could result..

[@cclarke6]

Even though there is adhesive in between, I wonder about bare steel and aluminum in contact.

[@fraserhardmetal7143]

@@cclarke6 In a conversion it is important to retain the basic integrity of the vehicle , removing paint to bare metal really compromises that. Having dissimilar unprotected metals in close proximity when there is a risk of condensation , seems to me to be a recipe for future problems. Better leave well alone and keep the vehicle as stock as possible with intact factory protection.

[@HumbleRoad]

Respecting the integrity of the chassis is a big part of my philosophy. As demonstrated in the video, these are not "unprotected metals" as you say. The dollop of P&L Marine cures to a thick rubbery waterproof bond. It is not a water based product.

[@fraserhardmetal7143]

@@HumbleRoad The surfaces to be bonded would only require keying with a light scuffing with a scotchbrite pad , degreasing , priming with the appropriate sikaflex product , then application of the adhesive. Removal of the vehicle's finish is not necessary and is neither received wisdom or accepted practice with commercial vehicle upfitters. The only occasion when bare metal is necessary would be for a welded joint. We forget how powerful these adhesives are - and if you have been used to old school practices , as a lot of us have , it is difficult to accept that they will deliver on performance and ease of use - if preparation is to specification. A floor on a RV is unlikely to stretch the capabilities of these modern adhesives - it is really worthwhile looking at the data sheets for these products and optimising the product for the application. When you think aircraft are stuck together with similar products we should not be unduly worried. Please don't take this as criticism of your work in any way - just a heads up . Everybody has their own way of working , yours is very thorough and of good quality - maybe what I said would save you time while still maintaining your quality and the vehicle's integrity.

[@DiabloOutdoors]

Amazing tutorial George. You're really a good teacher and craftsman. I have a question for you. Gluing the floor makes it permanent. Is it possible to screw the floor on the trusts instead so you can change it if you ever need to or to change the insulation? I know that there's little chance that you have to do it. But just in case...

Such a pleasure to watch your master class videos George. With the benefit of time and kaizen, are the methods and materials used in this video still your go-to, preferred flooring system?

[@normanmazlin6741]

We call those secret access points "soft patches" in ships. Too bad many van builders ignore their importance. A classic head-scratcher is the missing soft patch access over the floor access panel to the fuel pump in many Japanese vans.

[@kamleo1685]

George, why didn't you put rebates to hold/support the access panels in the subflooring? Add a thumb-hole or indent for lifting and removal of the panels and use a low strength caulk to keep the access panels in place.

[@HumbleRoad]

I explained that the chances of needing access are slim to none. If so, a plunge cut is all that's needed. A prudent compromise I think.

[@kamleo1685]

I heard. However, based on your thoroughness and speel regarding making provisions for future repairs I thought this would be a better approach. The future repairer would have no need to make a plunge cut and damage the subflooring that you worked so hard to fit, the insulation (cut into a plug attached to the panel), and, possibly, the paint underneath. As you said, that is someone else's worry.

[@popupity]

Thank you, George! This video helped me understand the thing I need to keep in mind when doing my own van floor. I remember from an earlier video you used a heavy rubber sheet over the floor to stop the thermal transfer. In this build you are gluing directly to the frame of the van. Does that mean that the plywood will act as the thermal bridge insulator?

[@HumbleRoad]

Yes, in addition to the dollop of P&L Marine adhesive.

[@FBall-im8ui]

why wouldn't you join the floor sheets with say biscuits? to insure they will not become uneven after time?? Just a thought

[@MNHemiGuy]

@humble Road. Would you still use the marine adhesive or would you go with something else. My fear is it would loosen over time, but maybe not. I don't want holes in the floor and like the alum floor stut over wood idea. Thinking of using 3M Panel Bonding Adhesive 08115, for a more glue weld like bond.

Why grind the paint off when glueing the aluminium floor joists? Does it have to be bare metal to stick well? What happens if an alluminium joist comes unstuck from a floor rib? Noisy?

[@HumbleRoad]

The adhesion is only as good as the surfaces it is bonded to. During the earthquake that is inside a van when driving, the forces on the paint will cause it to shear off the metal.

[@gregohb]

Would you do this same insulation for the ceiling? Heat rises, so it would seem to keep warm the ceiling is even more important than the floor

What is your reasoning for using aluminum (with its high thermal bridging and high cost) for the joists vs wood that does have some insulation properties and a much lower cost? Structurally both are certainly adequate for the application. Thanks for all the great videos.

[@HumbleRoad]

The cost at my local metal yard is minimal. The structure far exceeds wood in terms of supporting the weight of the components during the earthquake that is inside a moving van. But the primary reason that I choose aluminum in spite of the thermal bridging is its inorganic property. No moisture no mold no bugs no degrading over time.

[@immanuel162]

Hey George, what glue do you use to fuse the aluminum joists and foam board to the chassis? And what's the purpose of the primer in this case, is it just to provide a better surface for the glue to adhere to?

[@ms53ski]

I wrote you earlier about just discovering Van Life, all the youtube channels and especially yours. How hard is it to work with the 80/20? I am a handy guy, but haven't worked much with metal. Also, you talk about expense, about how much for a standard build?

[@HumbleRoad]

8020 or any extrusion is easy to work with providing you have the proper tools. 8020 is one of the more expensive brands.

[@davidkoterwas3126]

Very detailed. You can tell you take pride in your work. Just curious, for the 1" aluminum square joist, is that T5 or T6? I know the T6 is stronger (more money too), but since only spanning a few inches from each rib, I didn't think it would matter. We were thinking of using 3/4" solid aluminum instead, slightly better cost, and using 1/2" polyiso (less R-value, but adequate for our build). Do you think the 1/4" lower the solid square aluminum would be adequate compared to the 1" square tube for joist? Again, thanks for doing your videos...always enjoyable and helpful!

[@HumbleRoad]

Solid aluminum would be fine, IMHO. My main concern is be sure of transferring the weight of your modules or components directly down through the joist to the van floor. I always use layers within my insulation "package." If you've got 3/4" of internal height to play with and you want to use 1/2" polyiso, then throw in a 1/4" layer of HMV or fiber insulation. Just don't sandwich two layers of non-breathable panels (vapor barriers), you will get condensation between!

My question is: how long a wait for you to build my "Ship of the highways" I just turned 70 so time is limited. lol

[@HumbleRoad]

Ha! Well, the build takes approximately 10 months and the next build spot is October 2023

Hey George, I noticed on one of your newer videos you used 80/20 instead of this square metal tubing for the floors. Is there are specific reason, or is one just as fine as the other?

[@HumbleRoad]

Actually, it's the opposite. I started with 8020 floor joists and later switched to the aluminum square tubing.

@@HumbleRoad gotcha. Great work nonetheless. Do you think the glue works as a sufficient thermal break in cold temperatures? Thanks for taking the time to reply btw...

I now know how to spell Mamaluke. Thanks!

[@bikeninja956]

I see some people forgoing the floor framing or cross members and just using high compression with plywood ontop..any downsides to that?

[@HumbleRoad]

If the foam begins to sag in any way it will be a nightmare
