Part 1: Architect’s Guide 1 - 52 The careful application of all these façade components is a pre-requisite to ensuring a satisfactory efficiency. NO YES At the intersection with the wall, these facings must be separated by the partition wall. Likewise, vertically, the internal facings of the lining continue as far as the decking, by stopping the suspended ceiling Figure 6.9 Horizontal cross section at the junction between façade and partition 6.3.5 Steel roofing systems There are special techniques for treatment of metal roofing (film or spraying) in order to reduce the noise of impact caused by rain. 6.4 Thermal performance In order to guarantee an acceptable level of thermal comfort for the occupants of buildings with controlled energy consumption, national regulations determine the material requirements for thermal performance. These depend on the building end-use and location. The requirements can be defined in terms of: Restrictions on energy consumption needed for thermal comfort Restrictions on indoor temperature during the summer Minimum thermal characteristics of envelope and equipment (restricting heat loss – effect of thermal bridging). Section 6.3 dealt with different ways of conforming with regulatory requirements for the acoustic performance of steel buildings. The provisions do for the various partitions typically use mineral wool as a mattress in the composite walls and its presence in the walls that surround the rooms also protects them from heat loss. Between two floors, for example, calorific loss is reduced because layers of mineral wool are used in the composition of the floors (above and below). Separating the two layers of insulation means that the type and thickness of the materials can be varied, thereby eliminating a large amount of thermal bridging.
