BS 8298-2:2020 - Page 3

Design and installation of natural stone cladding and lining. Traditional handset external cladding. Code of practice | Status: Confirmed, Current

1 Scope This part of BS 8298 gives recommendations for the design, installation and maintenance of traditional handset external cladding of natural stone held directly to a structural backing structure by metal fixings. It covers:

1. a) the sampling of stone for testing and production control testing (PCT);
2. b) the provisions necessary for the cladding to perform its function satisfactorily;
3. c) the materials and methods most frequently used for stonework; and
4. d) the use of thermal insulation behind external cladding.

Loadbearing masonry or cladding held only by adhesion is not covered, nor is any type of cladding supported or held in position around the perimeter of stones or series of stones by metal framing (e.g. rainscreen). This document is not applicable to seismic loading or enhanced security scenarios (such as blast).

NOTE The general principles for cladding also apply to soffits and sloping surfaces.

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