I'm just ready to start sourcing and buying material for my wall and ceiling liners. I like the corrugated-honeycoam material used on the slider door, but, that seems to be proprietary. I bought my van from dealer stock, so, could not order the load area protection package.
The cheaper corrugated PVC stuff looks too flimsy. I don't care for the stiffer, transparent or translucent greenhouse stuff.
So, I favor the Celtec sign material. Yes, I'm fine with the plastic-industrial look. Wood would be a second choice. Then, you've got to do staining and/or sealing.
Either way, you've got to account for good structure and joints, likely working with standard 4x8 material. Material cuts for the ceiling are particularly problematic, with a 63-inch-wide by 11 1/2 foot ceiling space -- possibly with cover strips; and the fasteners. I do like the removable plastic fasteners, for the walls, at least.
I have seen the Inlad liner packages
, which, at first, seem overly expensive. Anyone use these? I'm not entirely sure if it's more like Celtec -- foamed PVC -- or like cell-corrugated PVC.
Inlad lists 148 in. std. length MR wall kit at $832, includes all fasteners, and panel lengths do not limited to 4x8 = fewer ceiling joints, and better fit. Ceiling kit adds $466. Shipping would be $150, assuming I get both kits.
So, I'm looking at Celtec at ePlastics
. 6mm for the walls (and maybe ceiling), 5 sheets walls + 3 sheets ceiling (with a lot of waste, unfortunately). Dark gray is $71.66 each. Light gray is $83.35, or $667.
The OEM-type plastic fasteners have previously been recommended to me, but, I can't find the fargin' post(s). I'd guess that 150 of 'em might be around $100. Then, I still need to figure out a fastening scheme and expense for the ceiling. And, probably would have to make joint cover strips.
So, light gray, $667 for Celtec sheets, guestimate of $100 for 150 plastic fasteners, and I'll throw in $30 for ceiling fasteners. Shipping of the Celtec adds $265 (though I might be able to hit up a sign shop to place an order, and eliminate shipping).
OK, walls & ceiling with Celtec = at LEAST $1062.
From Inlad, $1448.
So, the premium is $386 to buy from Inlad, with less frustration, and better fit and appearance. I'm thinking that's not so bad.
I don't have costs on doing it all in wood, so, anyone may contribute expenses, there.
The big problem is paneling the ceiling
-- where to put the joints? Because there's nothing to attach to at the cargo-cab joint, it looks like you need to be running material lengthwise, where it will be held up by fasteners at 3 crossbeams. So, if you use a 4x8 that way, you will have either run thin strips lengthwise on either side, or a 12 or 13 inch strip running up one side. Then, a piece of about 2 1/2 feet x 63 inches, ahead of the back doors.
I'd like to hear what type of sheet layout, fasteners and joints anyone else has used for the ceiling!
