Raised-Heel Trusses Save You Money and Time

With labor shortages and tight profit margins, construction professionals are under more pressure thanRaised-Heel Trusses ever to deliver energy-efficient homes on time. One way to work smarter is to build using raised-heel trusses. From the APA: “Also known as energy-heel trusses, raised-heel trusses deliver cost-effective energy performance especially when combined with continuous plywood or OSB sheathing.”

What is a Raised-Heel Truss?

A raised-heel truss is identical to a regular truss except that it is raised by way of a ‘heel’ that goes up from the top of the wall. This lifts the top chords (rafter) at the building’s edge, leaving more room for insulation above the wall plate. The raised heel allows for easier attic ventilation and is installed in the same way as a regular truss which means it requires no special tools or skills.

When raised-heel trusses are combined with taller wall sheathing, the builder and homeowner benefit from improved energy and structural performance.

Save Money

Another place to save money is on insulation. Thanks to the raised heel, insulation is not compressed over the top plate. Because insulation is not compressed and is full depth to the outside edge of the top plate, depending on the relevant energy code, you may be allowed to reduce the R-Value required in the attic. Even with less insulation, the raised-heel truss home will be more comfortable and energy-efficient.

When raised-heel trusses are combined with taller wall panels, they create a stronger building. From the APA: “With this system, the wall-to-truss connection is greatly enhanced, resulting in superior overall load path, including better resistance to lateral forces like wind or seismic activity.”

Raised-heel trusses will also get the home a lower Home Energy Rating Score (HERS) which means lower bills for the homeowner and easier code compliance. You can expect a HERS rating that is 4-6 points lower for homes with raised-heel trusses.

Benefits of Raised-Heel Trusses combined with Taller Wall Panels

  • Continuous load path makes for strong structural integrity by improving the connection between the wall and the roof.
  • Eliminates the need for blocking.
  • Reduced air infiltration at the top plate and through the edges of the insulation.
  • Full-depth insulation over the wall plates means you may be allowed to use less insulation.
