So where do you start? The Code uses the metric form of R-values, called RSI. But no more. Depending on the climate zone, builders may be able to meet the new Code standards by reducing framing and using higher R-value insulation. "There's always fear of the unknown; there's fear of change," says Richard Kadulski, an architect and member of the committee that wrote the new Code. In the past, the Code required a "nominal" R-value. more info. Sometimes this is also called the assembly’s fire endurance.
