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 Government responded to the 212 recommendations of the Royal Commission; allocated more than $136 million in the 2004-05 Federal Budget; and appointed Colin Thatcher as a member of the Australian Industrial Relations Commission.
