Attic Truss With Heel

One of the most important measurements needed to match an existing roof is called the heel height.

Attic truss with heel.

More importantly the raised heel provides the opportunity to increase energy efficiency to meet new energy code requirements. Raising the truss higher has two big advantages. Easy to build with. The extra height of a raised heel truss roof provides additional space for uncompressed attic insulation and the full depth of insulation to be extended right to the outside of the top plate.

Raised energy heel typical truss heel height is about 12 but may be designed to most any height per the building designer specification. It is raised higher with a heel that extends up from the top of the wall and elevates the truss at the building s edges. Truss heel height the vertical depth of the truss at the outside face of the bearing. Girder trusses are designed to carry additional loads other than standard roof loads.

Builders don t need special tools or know how to build with them. Below are some diagrams to help illustrate the measurement points. A truss with the same pitch and heel on both sides and a peak at the center is called a common truss. Ventilation eave baffles if needed for air flow.

Raised heel trusses are installed the same as conventional trusses. It greatly simplifies attic ventilation and it leaves ample room for insulation above exterior wall top plates. Standard heel typical truss heel height is about 4. These loads can be other trusses that attach by sitting on top of the girder or they may attach to the side of the girder using truss hangers.
