Thickness of Stone Cladding

[daveross]

Can anyone advise if there exists a standard for minimum recommended thickness for external granite cladding on multi-storey buildings??

About 20mm to 50mm seems to be common, depending upon the size of panel.&nbsp;&nbsp;I have seen &quot;strips&quot; (150mm wide by 1500mm long) that were in the 20mm thickness range, and have seen panels in the 1m square range with greater thickness, up to about 50mm, though I have seen similar full size panels in the 20mm range.<br><br>Thermal issues, rigidity of attachment, type of attachment (mechanical vs. adhesive,stainless steel vs. typical carbon steel), wetting and drying, natural rock integrity, sawing/polishing, sealants, and handling have all been issues to consider in the failure investigations I have done on exterior granite (or marble) cladding.<br><br>Good luck.

i agree with Ron but i would think 20mm is better be...<br>we dont have to forget the wieght of this panels ..<br><br>so 2 cm is great...i hope that make it logical.
