It is a flat fiber cement board manufactured with the most advanced technology,
made of cement, silica, cellulose fibers, and additives; hardened in autoclave.
During this process, the boards are subjected to high pressure and temperature,
obtaining a product resistant to humidity, of great durability and mechanical
resistance. Being at the same time as ductile and easy to work as wood and as
resistant and durable as cement.
Eterboard fiber cement boards meet the requirements of the Colombian
