How heavy is the fiber cement siding?

Weight of the fiber cement siding

Weight of the siding panels for finishing of the building is the important characteristic influencing a choice of specific material. Even when using the recommended manner of installation of the fiber cement siding, it is useful to know both the weight of a separate panel, and weight of square meter of already mounted facing material.

If you know the needed area and thickness of the fiber cement boards chosen, you can do it, using the known density of the fiber cement — 1,65 g/cm3, or using the table of weight of a fiber cement board below.

Weight of 1 sq.m. of the mounted fiber cement siding

The fiber cement siding can be mounted in two main ways, with overlap (with overlapping of panels) and end to end joint.

To determine the weight of one square meter of the fiber cement siding mounted with overlap we should take into account the area of mutual overlapping of panels. At the recommended overlap of panels of 40 mm we receive on 1 sq.m. of the area in a maximum 2800 sq.сm of the overlapping siding that gives thickness of 11 mm and 7200 sq.cm of the siding in one layer with thickness of 8 mm. If we know a density of the fiber cement siding equal 1,65 g/cm3, we receive:

2800*1,6*1,65/1000 + 7200*0,8*1,65/1000 = 16,9 kg/sq.m.

It comes that the weight of one square meter of the mounted fiber cement siding can reach 16,9 kilograms.

It is necessary to understand that it is the maximum possible weight at the recommended overlap of siding panels in 40 mm. If used the minimum allowed overlap in 30 mm the weight of one square meter of the mounted siding will be equal to about 15,6 kg.
