The range
Five kinds of PVC foam board, one factory
A PVC foam sheet is a rigid panel with a closed-cell foam core and a smooth solid skin. Which board you want depends on how hard the surface has to be and what goes on top of it. Here is how our five lines differ.
Free foam
Celuka
PVC Celuka foam board
Foamed against the die so the skin cures hard and dense. Takes routing, hinges and edge banding — this is the cabinet-door board.
- Thickness5–30 mm
- Density0.5–0.9 g/cm³
- Best forCabinets, doors
Co-extrusion
PVC co-extrusion foam board
Two layers in one pass: a light core under a tough coloured skin. Black, grey and colour stock available for high-wear panels.
- Thickness3–25 mm
- Density0.5–0.8 g/cm³
- Best forColoured panels
Laminated
Laminated PVC foam board
Foam board finished with wood grain, marble or solid-colour film. Ready to install — no spraying, no wrapping line needed at your end.
- Thickness5–25 mm
- FinishesWood, marble
- Best forFurniture, walls
WPC
WPC foam board
Wood flour blended into the PVC foam. Holds a screw like timber, still shrugs off water — used where joinery meets wet rooms.
- Thickness5–30 mm
- Density0.6–0.8 g/cm³
- Best forWet-room joinery

Ask our engineersWhy this material
What a PVC foam sheet does that wood cannot
Seven properties buyers keep coming back for — the reasons this material replaced plywood and MDF in signage, bathrooms and shopfitting.
0.3–0.9 g/cm³ Light, still stiff
Close to half the weight of solid PVC or timber, so freight and installation cost less while compression and impact resistance hold up.
closed-cell Waterproof, full stop
The core gives water nowhere to travel. No swelling, no mildew, no rot — coastal, humid and bathroom jobs behave the same as dry ones.
anti-UV Holds up to sun
Additives are dosed into every batch, so outdoor PVC foam sheet resists fading, chalking and brittleness in tropical and temperate climates alike.
class B1 Fire retardant
Self-extinguishing, no open-flame combustion, low smoke and non-toxic — it meets the fire rules that commercial fit-outs are inspected against.
CNC-ready Easy to work
Cut, drill, bend, weld, laser, screen print, paint or laminate with the tools already on your floor. No special plant needed for custom shapes.
acid-proof Corrosion and insect proof
Acids, alkalis, cleaning chemicals and termites leave it alone — the failure mode that ends the life of a wood panel simply is not there.
non-toxic Recyclable, formaldehyde free
Made from virgin material, reusable and recyclable, so the board clears green-building and procurement policies without an argument.

CNC & laser cutting
PVC foam board for CNC laser cutting: clean edges, no delamination, no fibre to burn.
Bathroom & kitchen
Waterproof PVC foam board for bathroom cabinet bodies, wall linings and laundry joinery.
Photo frame backing
PVC expanded sheet for photo frame backing and mounting boards — dead flat, stays flat.
If you are switching
Against the panel you use today
Most of our customers arrive holding a sheet of plywood, MDF or acrylic and asking what changes. Here is the honest comparison, including where another material still wins.
| Property | PVC foam board | Plywood | MDF | Acrylic |
|---|---|---|---|---|
| Weight, 18 mm | ~10 kg/m² | ~11 kg/m² | ~13 kg/m² | ~21 kg/m² |
| In standing water | Unaffected | Delaminates | Swells, fails | Unaffected |
| Fire behaviour | Self-extinguishing | Burns | Burns | Burns fast |
| Cutting and routing | Clean, no dust mask drama | Splinters | Heavy dust | Chips, cracks |
| Screw holding | Good at 0.6 g/cm³ and up | Best | Poor once wet | Needs inserts |
| Direct printing | Excellent | Needs priming | Needs priming | Good |
| Termites and rot | Immune | Vulnerable | Vulnerable | Immune |
| Optical clarity | Opaque only | Opaque | Opaque | Clear — acrylic wins |
Need transparency or a structural load path? Say so and we will tell you plainly that a foam panel is the wrong choice. For everything else — signage, shopfitting, wet-room joinery — a white PVC foam sheet outlives the timber it replaces.

Straight answers
PVC foam board questions we get weekly
What is the difference between PVC free foam board and PVC Celuka foam board?
Both come off the same kind of line; the skin is what separates them. Free foam board foams evenly throughout, giving a uniform, softer panel that prints and cuts easily. Celuka board is foamed against the die so the outer skin cures hard and dense — that skin is what lets you rout a profile, fit a hinge or band an edge. Signage takes free foam; cabinet doors take Celuka.
Which thickness and density should I order?
Print and display work is usually 3–5 mm at 0.5 g/cm³. Interior partitions and display fixtures sit at 8–12 mm. Cabinet and door panels go 16–18 mm at 0.55–0.6 g/cm³, higher if you are driving hardware into the face. If a screw-holding test matters, tell us the fastener and we will send two densities to try.
Is PVC foam sheet really waterproof?
Yes. The core is closed-cell, so there is no path for water through the panel and no fibre to swell. It does not rot, delaminate or grow mould, which is why it has replaced plywood in bathroom vanities, laundry joinery and coastal signage.
Can you print, laminate or cut the board to my sizes?
We laminate wood grain, marble and solid colour film, emboss, and cut to any size within 2050 mm width. Screen and UV printing are handled in-house for volume orders. Send the artwork or the film code and we will match it.
What is your minimum order, and can I get samples first?
MOQ is 300 sheets, or one 20 ft container mixing thicknesses and colours. Sample sheets of any board we make are free — you cover only the courier, and we credit it against your first order.
How long from deposit to loading?
7–15 days for made-to-order, and about 3 days if your size sits in stock colours. You get line photos at the first sheet and again at half-load, so nothing about the shipment is a surprise.
Do you supply certificates for customs and building control?
Every shipment carries an inspection report, packing list and fire-rating certificate. SGS, RoHS and REACH reports are available on request — tell us which authority is asking and we will send the right set.
