General principles for wall types

This section gives examples of wall types which, if built correctly, should achieve the performance standards set out in Table 1a of the section entitled "Guidance - Performance and introduction to provisions". Pre-completion testing will establish the compliance of the constructions built. The guidance in this section is not exhaustive and other designs, materials or products may be used to achieve the performance standards set out in Table 1a of the section entitled "Guidance - Performance and introduction to provisions". Advice should be sought from the manufacturer or other appropriate source. The walls are grouped into four main types (see Diagram 2.1).
