Aquapanel Cement Board

AQUAPANEL® Cement Board Indoor

The ideal tile backer board for wet and humid areas

The system solution for dryline interior walls and ceilings with AQUAPANEL® accessories

AQUAPANEL® Cement Board Indoor is a solid and durable tile backing used in wet and damp areas causing less installation costs. The cement board is 100% water-resistant and resistant to mould and mildew. AQUAPANEL® Cement Board Indoor is made of aggregated Portland cement with coated glass fibre mesh embedded in back and front surfaces. The ends are cut square and edges are reinforced for extra strength (EasyEdge®).

Benefits of AQUAPANEL® Cement Board Interior Systems

  • 100 % water-resistent
  • Resistant to mould and mildew
