External Cladding

No matter what form it takes, cladding provides a non-load-bearing weather protection and in most cases a decorative finish to whatever structure it is required to cover.

Any material may be used as a cladding provided that it is available in an acceptable form, and that it possesses the necessary properties, for example: (a) weather resistance; (b) durability; (c) strength to resist impact; (d) resilience to abrasion; (e) fire performance; (f) thermal insulation; (g) minimal maintenance and that it complies with current regulations (Approved Document B4 2000, Fire spread). The relationship between the material, its form and type, is shown in Table 2.1 with reference to Fig. 2.1.
