Truss heel height the vertical depth of the truss at the outside face of the bearing. Raised heel trusses can be installed in a single day.

Raised energy heel typical truss heel height is about 12 but may be designed to most any height per the building designer specification. Raised heel trusses also known as energy heel trusses deliver cost effective energy performance especially when used with continuous plywood or osb sheathing. Simply it is the thickness of the truss measured at the point where the bottom chord meets the top chord from the top of the top plate to the underside of the sheathing. The raised heel provides additional space for cheaper attic insulation and for the full depth of insulation to be extended right to the outside of the top plate.
