Standard panels are not built to cope with sustained moisture. In wet areas, water can penetrate unsealed edges and surfaces, leading to swelling and breakdown over time.

Choosing moisture-appropriate materials is essential for both cabinetry and structural elements.

Moisture-resistant MDF is a popular choice for vanities and cabinetry in humid environments. It offers the smooth, machinable finish of standard MDF with improved resistance to swelling.

High moisture-resistant particleboard is a cost-effective option for wet-area carcasses and cabinetry. It provides reliable performance in kitchens, bathrooms and laundries where budget is a consideration.

For the wettest zones, such as shower surrounds and splash-prone areas, waterproof panels offer the highest level of protection. PVC-based boards resist water entirely, making them ideal where moisture exposure is constant.

See Bord's PVC waterproof panels for these applications.

Where structural strength and high moisture resistance are both required, marine plywood is the benchmark. It is manufactured to withstand demanding, damp conditions without delaminating.

Whatever the substrate, the finish and edges matter just as much. Sealing edges and pairing moisture-resistant cores with durable laminate or veneer faces ensures long-term performance. Bord's laminate and melamine range offers hard-wearing surfaces suited to wet areas.

Wet areas are unforgiving, but the right panel choice makes all the difference. Matching substrate, finish and detailing to the level of moisture exposure delivers cabinetry and joinery that lasts.
