IBS PRIMAflex Fibre Cement Board
Description

IBS PRIMAflex is a cellulose fibre cement panel. Each panel has a smooth, uniform face and is ready to be finished with a variety of paint, lightweight plaster systems or overlaid with ceramic tiles, slate, or stone composite products.

The panels are manufactured in a high-pressure chamber (called an autoclave) from high-grade cellulose pulp fibre, finely ground sand Portland cement and water. This process makes the panels strong, durable, and non-combustible. It is also moisture resistant and can help with soundproofing.
