Armstrong World Industries expanded with a low-end bedroom furniture line. They bought Gilliam Furniture in 1986, bought and repurposed the former Stehle polyester factory in Carysbrook, Virginia later that year, bought Westchester Group in 1987, and Gordon's in 1988; as well as making a major expansion to Thomasville that year. In 1995, Thomasville Furniture was sold to Interco (which became Furniture Brands International), a leading furniture manufacturer, with such brands as Broyhill and Lane. Armstrong Holdings Inc. used to produce asbestos, either of two incombustible, chemical-resistant, fibrous mineral forms of impure magnesium silicate, used for fireproofing, electrical insulation, building materials, brake linings, and
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
