R-value (insulation) contain no trapped CFCs or HFCs (e.g., half-pound low density foams). On certain brands, twenty-year tests have shown no shrinkage or reduction in insulating value. This has led to controversy as how to rate the insulation of these products. Many manufacturers will rate the R-value at the time of manufacture; critics argue that a more fair assessment would be its settled value. The foam industry adopted the LTTR (Long-Term Thermal Resistance) method, which rates the R-value based on a 15-year weighted average. However, the LTTR effectively provides only an eight-year aged R-value, short in the scale of a building that
Royal Commission into the Building and Construction Industry of the Australian Building and Construction Commissioner (ABCC). The role of the ABCC was to monitor and promote appropriate standards of conduct throughout the building and construction industry. The ABCC operated between 2005 and 2012. The Commission's own estimate of its expenditures, as at the date of publishing its report, was that it had spent approximately 60 million. This figure makes this Royal Commission one of the most expensive in Australia's history.
