Design and installation of natural stone cladding and lining. Internal cladding and lining. Code of practice | Status: Current

1 Scope This part of BS 8298 gives recommendations for the design, installation and maintenance of internal cladding and lining of natural stone held directly to a structural background by fixings with or without adhesive. It is applicable for both commercial and residential locations. It covers four categories of construction build up:

1. a) internal cladding ≥20 mm thick, with a cavity, supported at each floor level, mechanically supported and restrained;
2. b) internal lining ≤2.4 m height, ≥20 mm thick (e.g. ≥600 mm × 600 mm to 2 400 mm × 600 mm) supported at floor level, stack-bonded, on adhesive, mechanically restrained to the substrate;
3. c) internal lining ≤2.4 m height, ≥12 mm to ≤20 mm (e.g. ≤600 mm × 600 mm), supported at floor level, stack-bonded, on adhesive, mechanically restrained to the substrate; and
4. d) ceilings, soffits and sloping surfaces with a cavity mechanically supported and restrained.

Stone held only by adhesion is not included. It covers:

1. 1) the sampling of stone for testing and production control testing (PCT);
2. 2) the provisions necessary for cladding and lining to perform their function satisfactorily; and
3. 3) the materials and methods most frequently used for stonework.

This document is not applicable to seismic loading or enhanced security scenarios (such as blast).

NOTE Different cladding methods are covered in the other parts of BS 8298 (see Foreword).

This standard excludes composite stone slabs, such as honeycomb-backed stone, and open internal courtyards.
