CBOARD HD

CBOARD HD

OVERVIEW

Cboard HD is a strong and durable high density fiber cement board with superior physical properties. It has the same composition as Cboard® RG (regular) but with increased physical properties. The high density is reached by hydraulic pressing.  

Cboard® HD can be used for interior as well as exterior applications and it has advanced water resistance properties. Beyond the smooth surface achieved, Cboard HD is available in different finishing textures including engraved wood patterns, plaster effects, natural stone surfaces, and grooved finishes.
