Ramco hicem Fibre Cement Board
Ramco Hicem Boards effectively outperforms existing building materials on all important performance parameters, including flexural strength, impact strength and durability. Hicem Boards are strong, non-combustible, water-resistant and are not affected by pests and termites.
Hicem Boards is manufactured using cement, cellulose fibres with performance enhancing special additives. Hicem Boards are made as per IS:14862-2000 standard in a laminar process and then autoclaved to give a stable crystalline structure.
The resultant crystalline structure makes the board durable and dimensionally stable even in adverse environments. Further, Hicem Boards come with good acoustic and thermal insulation properties to meet various end applications.
DIMENSIONAL STABILITY
Hicem Boards are cured under HPSC (High Pressure Steam Curing) which causes an irreversible matrix change providing high dimensional and chemical stability accompanied by low alkalinity.
SEAMLESS FINISH
Hicem Boards can provide seamless finishes when installed with most forms of paints, wall papers and laminates.
APPEARANCE
Hicem Boards have an off-white, superior texture making it suitable for all kinds of finishes.
The surface of the board can be easily decorated with most varieties of paints, wall papers, laminates, veneers and ceramic tiles. These boards are compatible with common building materials, including galvanized steel and anodized aluminium.
