Hardie Board is fiber cement siding by one of the first successful manufacturers of this material: James Hardie Building Products. Hardie Plank and Hardie Panel are two of their most popular products. The cement fiber material is a composite of ground sand, cellulose fiber, and other proprietary additives. This product is also known as cement fiber facing, cement facing, and cement fiber facing.

Fiber cement siding in Oklahoma City may look similar, depending on the texture of the panels during the manufacturing process, to timber clamber or cedar shingles. Sand, cement and wood pulp are mixed with water to produce a rolling slurry which is pressed into sheets together, allowing for nearly any siding design.

It squeezes the water, presses a pattern over the surface of the plates. The product is baked in autoclaves and then separated, tested for strength and painted into individual panels with high-pressure steam. The boards might look like wood, but the properties of the boards are far better than wood. The cellulose fiber is added, so it does not crack so that the board stays flexible.

The material is longer resistant to insects and the rot than most woods and stucco. It's also fireproof, and withstands storms wind and debris which is why it is such a popular fiber cement siding in Oklahoma City.
