Van Upholstery Fabric & Wall Panel Material

Fabric is where a van build stops looking like a cargo van. It's also where DIY builds most often go sideways — residential upholstery in a vehicle fades, fuzzes at the edges, and doesn't meet the flammability standards a vehicle interior should. Everything in this collection is contract- or transportation-grade and sold by the linear yard on 54" rolls, so you can order exactly what your panel layout needs. Marathon Tweed (also sold as Duramax) is the default wall-panel fabric of the conversion industry — 100% polyolefin, woven, hydrophobic, with extra UV stabilizer in the yarn for RV and campervan service. Marathon Plus is the same tweed heat-welded to 1/8" closed-cell Landau foam, which halves your panel-wrapping time. For seating, dinettes and cushions we carry four Nassimi lines: Bleecker, Varick, Minetta, and the PVC-coated Moxie. We use these materials in our own Roanoke builds, which is why the spec notes below are blunt.

How to Choose Van Fabric

1. Wall panels and seating are different jobs — buy different fabric

Walls, ceilings, and headliner: Marathon Tweed ($19.16/yd). Woven polyolefin, chemically inert, hydrophobic (won't absorb spills or stains), static resistant, and it meets MVSS 302, CAL-117, and UFAC Class 1. It's non-stretch, which matters: it wraps flat panels beautifully and fights you on compound curves. Roll width 54", roll length approx. 50 yd.

Seats, cushions, dinettes: the Nassimi lines, where abrasion resistance is the number that counts. All are 54" wide and meet CAL TB 117, NFPA 260 and UFAC Class 1.

2. Read the abrasion and weight numbers, they predict how the van ages

For context: 100,000 double rubs is heavy-duty contract seating — plenty for a dinette two people use. Moxie's 250,000+ is a different category, and it's coated, which is why it's the answer for the seat you get into wet, the bench the dog sleeps on, or a build that gets rented out. Moxie also carries a cold crack rating of -20°F, 300 hours of colorfastness (AATCC 16.3), and 10% bleach dilution resistance — real numbers for a van that lives outside.

Varick's linen content gives it a natural, matte hand that photographs beautifully and is the current favorite for "cabin" interiors. Minetta at 19 oz is the heaviest of the woven options and the most forgiving of a slightly imperfect cushion build.

3. Marathon Plus is the shortcut worth paying for

Marathon Plus ($45.56/yd, sold in 15-yard rolls) is Marathon Tweed heat-welded to 1/8" closed-cell cross-linked polyethylene Landau foam, 2 lb/ft³ density, rated -76°F to 194°F, meeting MVSS 302. What it buys you:

• One material instead of two. No separate foam layer, no second adhesive pass — it cuts your adhesive requirements roughly in half.
• A smooth finish over imperfect substrate. The foam hides the seams, screw heads and minor telegraphing in your panel material.
• Sound and thermal benefit on top of the Thinsulate in the cavity.

Pricing steps down with volume: 15–30 yd is $41.74/yd, 45+ yd is $36.76/yd. Order in roll increments (15, 30, 45) to get correct roll pricing.

4. Estimating yardage without over-buying

At 54" width, a rough working method for a 144" high-roof van: walls and ceiling typically run 12–18 linear yards depending on how much of the ceiling gets wrapped and how many window cutouts you have. Add 15% for pattern direction, wrap-around edges (allow 2" past the panel edge on all sides), and mistakes. Buy it all at once — dye lots vary slightly between runs, and a panel from a second order can read a shade off on the same wall.

5. Adhesive and technique

Tweed is non-stretch and woven, so it does not want to be pulled around a curve. Practical rules from the bench:

• Spray both surfaces with a high-temp contact adhesive (a 90-class 3M product or equivalent), let it flash off, then lay it down — contact adhesive doesn't get a second chance.
• Relief-cut inside corners rather than stretching the weave; a stretched tweed shows a distorted grain line forever.
• Wrap and staple on the back face of the panel. Staples anywhere visible are the tell of a rushed build.
• Colors vary slightly by dye lot and screens lie — order a swatch if the exact shade matters.

6. Match the fabric to trim you're already buying

Our GoCode Sprinter and Transit trim kits can be ordered upholstered in Grey Heather or Black Marathon Tweed straight from the factory. If you're wrapping walls in Marathon Tweed, spec the trim in the same colorway and the whole interior reads as one build instead of a collection of parts.

Frequently Asked Questions

What fabric do professional van builders use on walls? Marathon Tweed, almost universally. It's 100% polyolefin, hydrophobic so it won't absorb spills, static resistant, and its High Ultraviolet yarn contains extra UV stabilizer specifically for RV and campervan applications. It also spot-cleans, which matters more than anything on a surface people lean on with muddy shoulders.

How many yards do I need for a Sprinter 144? Plan 12–18 linear yards of 54" material for walls and ceiling, plus 15% for wrap allowance and errors. A 170" or 170" EXT needs proportionally more. Cushions and a dinette are separate — figure those from your cushion dimensions plus seam allowance.

Is Marathon Tweed stretchy enough for curved panels? No. It's a woven, non-stretch fabric. Design for flat or single-curve panels and relief-cut your corners. If you have a compound curve — a wheel-well cap or a headliner shelf — either build the panel in sections or use a coated material like Moxie, which conforms differently.

Which fabric holds up to dogs and wet gear? Nassimi Moxie. The PVC-coated surface hits 250,000+ double rubs, resists 10% bleach dilution for cleaning, and has a -20°F cold crack rating. It wipes clean instead of absorbing, which is the whole game with a wet dog. Marathon Tweed is hydrophobic and handles spills well, but it's a woven surface, not a wipeable one.

Do these fabrics meet vehicle flammability requirements? Marathon Tweed meets MVSS 302, CAL-117 and UFAC Class 1. The Nassimi lines meet CAL TB 117, NFPA 260 and UFAC Class 1. Marathon Plus foam meets MVSS 302. These are the standards a vehicle interior should be built to; residential upholstery generally isn't tested to them.

Can I get all colorways by the yard? Not always. Nassimi stock varies — only colors physically in the warehouse are available by the linear yard, and other colors can be ordered by the roll (or by contacting our sales team for bulk). Marathon Tweed is stocked broadly in over two dozen colorways. Call the shop if you need a specific color in a hurry.
