Fixing of thin stone - PDF
Performance and testing of fixings for thin stone cladding
This report is concerned with the fixing of natural stone cladding units as part of a curtain wall or rainscreen. Developments in the cutting and handling of stone mean that natural stone can now be cut, depending on the stone type and quality, to thickness as low as 20 mm. This has a number of implications for the fixing of natural stone units, which make them different from the more traditional use of stone at thickness of 40-75 mm.
Stone cladding units are subject to temperature and moisture movement. Thinner stone units have less thermal mass and undergo greater thermal movement.Thin stone units are more likely to be saturated through their thickness and undergo greater moisture movement.
This report details the loads and movements on stone cladding, describes the different methods of fixing stone cladding units and methods of test to ensure their satisfactory performance.
