Camper van interior finishing: walls, ceiling and paneling
After insulation and flooring comes the part where your camper really takes shape: interior finishing. Cladding walls and ceiling gives your van a homely feel while protecting the insulation underneath. In this guide we cover the most common materials, how to install them, and what to watch out for to get a clean result without adding unnecessary weight.

Wall cladding materials
There are four common options for camper walls, each with their own pros and cons:
Birch plywood (3-4 mm) is the most popular choice. It's lightweight, strong and looks warm. You can leave it natural, oil it or varnish it. Birch bends well along curved van walls when dampened or when using thin sheets. Expect ~680 g per m² per mm thickness.
Cork wall covering (3-6 mm rolls or tiles) gives a unique look and dampens sound. Cork is naturally moisture-resistant and adds a small amount of extra insulation. It's more expensive than plywood and harder to bond neatly on curved surfaces.
Upholstery fabric and faux leather can be applied with contact adhesive or staples onto a thin backing board. Suitable for specific zones like around the bed or seating area. Not practical for the entire van due to cleaning difficulties.
Tongue-and-groove boards (spruce or ayous, 8-10 mm) give a rustic look. They are heavier than thin plywood though. Suitable if you want a woody, cottage-style interior. Mount them on a batten frame with adequate ventilation behind.
Ceiling finishing: lightweight and ventilation
The ceiling needs extra attention because the weight hangs directly above your head and heat rises upward.
Keep the ceiling as light as possible. 3 mm poplar or birch plywood is thick enough when mounted on a batten frame that holds the insulation in place. For an even lighter alternative you can stretch fabric over a frame, but getting it taut is trickier.
Always leave a ventilation gap between insulation and cladding. A minimum of 10-15 mm space prevents moisture from building up behind the panels. This is especially important on the ceiling where warm, humid air rises. Ideally place ventilation openings at the edges or use perforated panels.
Fix ceiling panels with stainless steel screws into the purlins (the cross beams of the van roof). Use pop rivets or rivet nuts if the purlins are unreachable. Gluing works too, but gives you no option to remove panels later for maintenance on wiring or insulation.
Tip: number your ceiling panels and take a photo before mounting. This way you know which panel goes where when you need to remove them.
Calculating material needs
Measure each wall section and the ceiling separately. Camper walls are rarely straight or rectangular, so work with the largest dimensions and add 10-15% extra for cutting waste and mistakes.
To calculate your total wall area, use the surface area calculator. Enter each wall section separately and add the results together. Remember to subtract windows, doors and cabinet areas from the total.
Price indication per m²:
• 3 mm birch plywood: €8-€15
• 4 mm cork wall tiles: €15-€30
• Upholstery fabric: €10-€25
• Tongue-and-groove spruce: €12-€20
Order sheets in the largest size that fits in your van. Large sheets (244 x 122 cm) are cheaper per m² but difficult to handle inside a van. Consider pre-cut half sheets (122 x 61 cm) for easier handling.
Keeping weight in check
Interior finishing seems light, but it adds up quickly. A complete wall cladding of 3 mm birch plywood in a standard L2H2 van easily weighs 25-35 kg. Add ceiling, fasteners and trim strips and you're already at 40-50 kg.
Track your total build weight with the weight calculator. Enter interior finishing as a separate item so you know exactly what it costs in payload capacity.
Weight savings come from small choices:
• 3 mm poplar plywood instead of 4 mm birch saves ~30% weight
• Fabric on the ceiling instead of wood saves 2-4 kg
• Skip wall panels behind fixed cabinets (nobody sees them)
• Avoid MDF: it's heavier than plywood and not moisture-resistant
Budget planning
Interior finishing costs range from €300 for basic wall cladding to €800+ if you use cork or hardwood trim strips.
Typical budget for an L2H2 van:
• Wall cladding (birch plywood): €150-€250
• Ceiling panels: €50-€100
• Batten frame and fasteners: €40-€80
• Trim strips and corner profiles: €30-€60
• Adhesive, sealant and sanding materials: €30-€50
Track your costs with the cost calculator. This shows your total build cost and where you might save.
Budget tip: check second-hand marketplaces or timber offcut sales for plywood. You can often buy leftover sheets at half price. For a camper van you don't need perfect A-grade quality.
Tips for a professional finish
The difference between an amateur and professional finish is in the details:
Corners and edges: use flexible trim strips (PVC or aluminium) to neatly cover the transition between wall and ceiling. Wooden quarter-round mouldings also work but follow curved walls less smoothly.
Access panels: plan ahead where you'll need access to wiring, plumbing or insulation later. Make panels that open with push latches or magnetic catches instead of screwing everything shut. You'll thank yourself later.
Seams: finish seams with flexible acrylic sealant rather than rigid wood filler. Your van moves and vibrates, and hard filler cracks and comes loose. Clear or wood-coloured sealant is least noticeable.
Sanding: sand plywood edges with 120-grit sandpaper before finishing. Rough edges stand out more in a small space and feel unpleasant to touch.
Pre-treatment: apply a coat of varnish oil or matte lacquer to untreated plywood. This protects against moisture and makes the surface easier to keep clean. Two thin coats are better than one thick coat.
Maintenance and durability
A well-finished interior lasts years with minimal maintenance.
Plywood treated with oil or lacquer can be wiped down with a damp cloth. Apply a fresh coat of oil every 2-3 years when the wood feels dry or stains no longer wipe off easily.
Cork is naturally antimicrobial and needs little maintenance. A coat of cork wax every 1-2 years keeps it supple and water-repellent.
Watch for condensation points: check behind panels annually at spots where you suspect condensation (around windows, near the door opening). Early detection prevents mould growth.
For damage: small scratches in plywood can be sanded out and touched up with oil. Replacing a damaged panel is straightforward if you followed the numbering tip and used push latches.
Avoid aggressive cleaning products on wood. Green soap diluted in water is sufficient for most dirt.

Frequently asked questions
- What is the best material for camper van walls?
- Birch plywood at 3-4 mm is the most common choice. It combines low weight with a warm look and is easy to work with. For a more unique appearance you could consider cork, but it's more expensive.
- How do I attach wall panels in a camper van?
- Screw a batten frame of wooden battens (18x35 mm) onto the purlins or ribs of the van with stainless steel screws. Attach the wall panels onto this frame with short screws or contact adhesive. Don't use nails: they vibrate loose from driving vibrations.
- How much does camper van interior finishing weigh?
- Expect 40-50 kg for complete wall cladding and ceiling in an L2H2 van (birch plywood). With tongue-and-groove boards it becomes 60-80 kg. Poplar plywood saves roughly 30% weight compared to birch.
- Do I need ventilation behind wall panels?
- Yes, leave at least 10-15 mm space between insulation and cladding. Without ventilation, moisture can build up and cause mould. This is especially important for the ceiling and north-facing walls of the van.
- How much does camper van interior finishing cost?
- Budget €300-€800 depending on your material choice. Birch plywood is most affordable (€300-€450 total), cork or tongue-and-groove boards cost more (€500-€800). Offcuts and second-hand materials can save significantly.
- Can I remove wall panels later?
- That depends on your mounting method. Screwed panels are easy to remove. Glued panels are difficult to take off without damage. Preferably use screws or push latches in areas where you need later access for maintenance.
