Raised heel trusses (a.k.a. energy-heel trusses) allow for deeper attic insulation over the top plates and provide ample space for soffit-to-ridge roof ventilation. This APA guide describes the components of a raised-heel truss framing system and offers guidance on installing them efficiently to meet code and save time. Continuous plywood or OSB wall sheathing can completely eliminate code-required blocking, and provides a better wall-to-truss connection, resulting in walls with improved resistance to lateral loads from wind and seismic activity.
