In Pennsylvania zone 3 requirements apply with a required Uo value of 0.079. This value cannot be directly used to define a baseline envelope R-values because the Uo value is dependent on both the size of the manufactured homes and insulating levels together. However because manufactured homes are typically built to standard dimensions baseline U-values can be estimated with reasonable accuracy. Figure : Uo Baseline Requirements The HUD Code required insulation levels can be expressed as a set of estimated envelope parameters to be used in user defined reference home function.
