Abstract: An insulated framing system for providing improved thermal insulation in a building such as a home includes structural supports such as dimensional lumber studs or metal studs having a rigid insulator attached along at least one edge thereof. The resulting composite member provides a thermal break between the structural support and the sheathing, wallboard, or other structure supported thereby. Further, the addition of the insulator deepens wall cavities, permitting installation of more insulation material. One or more wings extending from the insulator into the cavities facilitates installation and retention of insulation material in the cavities prior to installation of sheet good finish materials such as gypsum wallboard.
