Thermal conductivity common use in the construction and textile industries. The construction industry makes use of units such as the R-value (resistance) and the U-value (transmittance). Although related to the thermal conductivity of a material used in an insulation product, R- and U-values are dependent on the thickness of the product. Likewise the textile industry has several units including the tog and the clo which express thermal resistance of a material in a way analogous to the R-values used in the construction industry. There are a number of ways to measure thermal conductivity. Each of these is suitable for a limited range
Royal Commission into the Building and Construction Industry Australian Naval Reserve and conservation and arts organisations." The Commissioner was appointed to investigate certain matters in relation to the building and construction industry. Those matters were defined in the Letters Patent as follows: The powers of Royal Commissions in Australia are set out in the enabling legislation, the . Royal Commissions, appointed pursuant to the "Royal Commissions Act" or otherwise, have powers to issue a summons to a person to appear before the Commission at a hearing to give evidence or to produce documents specified in the summons; require witnesses to take an oath or give an affirmation; and
