The grammage of the mesh cloth refers to the mass per unit area, usually expressed in grams per square meter.

Generally, in the construction of thermal insulation mortar, this standard is followed, and then the same standard is also followed in the external wall construction.

For example, if the aperture of the standard mesh cloth is 5mm, it can be approximated as 55.
