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 the First Report made findings which directly and adversely affected the interests of the applicants. The Court also rejected the contention that the First Report shows that the Commissioner was, or could reasonably be apprehended to be, so committed to conclusions which he had already formed that he would be incapable of altering those conclusions. An Interim Building Industry Taskforce Report was delivered on 15 August 2002; and a Building Industry Taskforce Report delivered. The Commissioner presented his final report to the Governor-General on 24 February 2003; and the report was tabled in Parliament on 26 and 27 March 2003.
