This document provides details on installing stone cladding on buildings, including considerations for the stone properties, design loads, dimensional changes to the building, and height of panels. It recommends a minimum thickness of 20mm for hard stone panels like granite and marble below 3.7m high, increasing to 40mm thick above 3.7m high. For softer stones like limestone, the recommended minimum thickness is 50mm for panels below 3.7m and 75mm thick for panels above 3.7m. Proper specification of panel thickness depends on factors like processing equipment limitations and the type of fixing and anchoring system used.

Cladding Installation
Before installation of any stone cladding to either the
interior or the exterior of a project a number of design
considerations must be taken into account.
The physical properties/characteristics of the stone, as
provided by the supplier
Design loads and safety factors for the cladding
Expected wind loads on the exterior building - calculated
from AS1170.2, or for small structures, calculated from
AS1288 Appendix D.
Possible dimensional changes to the building due to
wind-load sway, thermal expansion/contraction, seismic
movement, creep and shrinkage.
Height above the ground at which the panel is to be
affixed.
Panel Dimensions
The selection of an appropriate panel size and thickness
(as mentioned above) is dependent on a number of
critical factors that must be considered prior to final
specification. It should also be kept in mind that there are
restrictions to panel sizes based on limitations of
processing equipment size of quarried material and the
type and size of fixing and anchoring system employed.
As a general rule however "continuously supported hard
stone panels (granite, marble, travertine?) below 3.7m
above ground level should be at ,east 20mm thick, and
soft stones (limestone, sandstone) 50mm thick. When
more than 3.7m above ground level hard stone should be
at least 40mm thick and soft stones 75mm thick."
