APA Reports on Installation of Raised-Heel Trusses

APA–The Engineered Wood Association report explains how structural paneling can take the place of 2x blocking when setting energy-heel roof trusses.

APA System Report: Use of Wood Structural Panels for Energy-Heel Trusses is part of the APA Publications Library and can be downloaded for free. If you want the printed version, it’s $1.

Energy-heel trusses, also called raised-heel trusses, have short, vertical components where the truss meets the outside wall, allowing for full-depth insulation. In a conventional truss, or in a conventionally framed wall, insulation can get compressed at the wall line, reducing its effectiveness.

Raised-heel trusses improve energy efficiency, but the added distance between the roof sheathing and the top plates of the wall complicates the required lateral support, the APA said. Although 2×4 or 2×6 blocking is typically used, the new report outlines how structural wall sheathing can take its place.

The report includes illustrations, nailing schedules, and other details.
