Compare the actual construction
ABA versus MDF.
Start beneath the finish.
Two decorative wall panels can look similar while using different substrates. Compare the complete selected products, their installation systems and the same unit of area.
Different cores.
Different approval questions.
Neither a decorative photograph nor a trade name is enough to specify a panel.
| Decision | Reference ABA panel | MDF-based wall panel |
|---|---|---|
| Core construction | Mineral-filled PVC skins and foamed PVC/mineral centre; wood-free substrate. | Wood-fibre MDF substrate, generally combined with a specified decorative facing and backing. |
| Water exposure | Assess absorption, swelling and joint evidence for the chosen product. | Assess the selected moisture-resistant board and the complete facing, edge and sealing system. |
| Weight comparison | July nominal reference calculates to 5.1 kg/m². | Obtain the exact product’s kg/m², including its thickness and finish. |
| Panel handling | Consider full-size dimensions, flex, weight and approved lifting practice. | Consider the same factors using the selected board and format. |
| Wet detailing | Joints, corners, penetrations and perimeters require the approved treatment. | Joints, corners, penetrations and perimeters require the approved treatment. |
| Fire and surface results | Use the exact specimen, method and end-use scope. | Use the exact specimen, method and end-use scope. |
Compare kilograms
per square metre
Panel width can distort a whole-board comparison.
The reference ABA board is 950 mm wide and 2400 mm high. Its nominal area is 2.28 m², so 6 mm × 850 kg/m³ gives an indicative 5.1 kg/m², or around 11.6 kg per board.
A wider MDF panel covers a different area. Comparing its whole-panel weight with a narrower ABA board combines material and format differences. First compare kg/m²; then compare installed coverage, packaging, breakage and handling.
Actual weights and tolerances should come from the selected production specification. A calculated nominal weight is not a guaranteed packed or shipping weight.
Keep the comparison
technically fair
A strong range proposition does not need claims the evidence cannot support.
Wood-free ABA provides a different substrate route from MDF, but it does not justify calling every competing MDF shower system unsuitable for wet rooms. Established MDF-based products use their own facings, protected edges and installation systems.
Do not turn different scratch-test methods into a multiple such as “six times stronger”. Do not assume a thin panel is automatically easier to install in every layout. Evaluate full-size panels, cutting, joint fitting, adhesive compatibility and finished corners together.
For a distributor, the better comparison includes the approved sample, technical documentation, installer guidance, replacement supply and the final cost per installed square metre.
