ETERPAN® Medium Density Fibre Cement Board for Rigid Wall Underlay
Description

ETERPAN® MD is a fibre cement board which can be used as a rigid wall underlay (RWU). With non-combustible properties, the sheets are specifically created for use in both residential and commercial construction applications. It enables the downward flow of water or moisture, preventing any potential damage to the framing and insulation components.

ETERPAN® MD, when used as RWU, has the advantage of being able to remain exposed for a period of up to 90 days before the installation of the external cladding. This allows for efficient construction progress while ensuring the durability and protection of the underlying structure.

Residential:

  • 6mm x 1200mm x 2400mm
  • 6mm x 1200mm x 3000mm

Commercial:

  • 9mm x 1200mm x 2400mm
  • 9mm x 1200mm x 3000mm

ETERPAN® MD fibre cement board is created using the advanced flow-on technology. This durable board is composed of Portland cement, cellulose fibres, sand, and water.
