Control of Asbestos Regulations 2006 were entirely preventable and the defendant fell far short of the high standards required. This should serve as a warning to others about the dangers of asbestos and the legal requirement to manage it properly." Asbestos is a naturally occurring group of silicate minerals that can readily be separated into thin strong fibres that are flexible, heat resistant and chemically inert. Within the United Kingdom and elsewhere in the world, asbestos was used extensively as a building material from the 1950s to the 1980s. It was used as a means of fireproofing as well as insulation and any building built
Dynamic insulation medium (m) is known. The air permeability of some materials that could be used in dynamically insulated walls or ceiling are listed in Table 3. Air permeability data is crucial to the selection of the correct material for the air control layer. Further sources of air permeability data include ASHRAE and Kumaran. Table 3: Measured Air Permeability of Building Materials (1) Pressure drop calculated at flow rate of 1 m/mh The application of the theory of dynamic insulation is best explained by way of an example. Assume a house of 100 m floor area with a dynamically insulated ceiling. Putting
