BS 6093:2006+A1:2013

This British Standard gives recommendations for the design of joints and the use of jointing products in building construction. Following an analysis of joint functions and of the performance of the parts to be joined, joints are classified in this standard on the basis of the movements and inaccuracies they have to accommodate. Mechanisms by which joints operate are identified and recommendations are made on the use of sealants and gaskets. Some emphasis is placed on weather resistance of joints in the external envelope of buildings. The code does not present guidance in the form of a catalogue of proven joint designs, because the extent to which a design is appropriate to a particular use depends on circumstances specific to the building, e.g. its exposure, desired performance, durability and costs. The code therefore draws attention to matters that need consideration, in order that solutions may be developed that are appropriate. The code does not cover: rigidly connected joints (except type1 joints, see4.6.4.1); joints within components normally made in a factory, such as those around opening lights in windows; the load-bearing functions of structural joints; glazing (see BS6262); joints in service pipes and ducts and their connections to appliances; methods of test for joints or for jointing products. All figures in this standard showing detailed joint designs illustrate principles in a recognizable context and are not production drawings of proven and universally applicable joints.
