Five Moisture-Control Layers to Evaluate
123451Panel / core
Moisture response varies by formulation and product model. Confirm applicable water-absorption and dimensional-change data.
2Surface finish
Film, veneer and co-extruded surfaces have different exposure limits. Check the complete finished product, not only its core.
3Cut edges & hollow ends
Cut edges and open cavities may require model-specific treatment or drainage. Do not assume that a coated face protects every exposed edge.
4Joints & penetrations
Movement joints, corners, outlets and pipe penetrations need project-specific detailing that also allows the required material movement.
5Substrate & waterproofing
The wall substrate, waterproofing membrane and water source must be addressed independently. A decorative panel does not replace these measures.
Moisture-Exposure Application Guide
| Application / exposure level | Status | Guidance |
|---|---|---|
| Standard interior wall | Model-specific | Confirm the selected indoor panel and installation method. |
| Humid dry area | Conditional | Check surface finish, substrate condition and ventilation. |
| Occasional splash | Conditional | Confirm product approval and compatible joint, edge and penetration details. |
| Direct shower / continuous wet zone | Project review | Do not specify from this article alone; verify an approved product and a complete waterproofing system. |
| Basement with leakage or mould | Do not cover | Identify and correct the moisture source and assess affected materials before covering the wall. |
| Semi-outdoor / exterior | Exterior-rated only | Use only the applicable exterior-rated profile and system; shelter alone does not make an indoor panel suitable. |
Kitchen
Evaluate heat, fire requirements, steam, cleaning chemicals and equipment clearances.
Special environments
Pools, coastal areas and severe climates require separate product, exposure and fastener review.
