Attic Truss With Heel

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.

Attic truss with heel.

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. Standard heel typical truss heel height is about 4. It greatly simplifies attic ventilation and it leaves ample room for insulation above exterior wall top plates. 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.

Builders don t need special tools or know how to build with them. A raised heel truss is identical to a conventional truss except for one difference. Raising the truss higher has two big advantages. Below are some diagrams to help illustrate the measurement points.

Raised heel trusses 9 1 4 to 15 1 4 inches in depth. Easy to build with. A truss with the same pitch and heel on both sides and a peak at the center is called a common truss. 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.

One of the most important measurements needed to match an existing roof is called the heel height. Raised heel trusses are installed the same as conventional trusses. Girder trusses are designed to carry additional loads other than standard roof loads. Truss heel height the vertical depth of the truss at the outside face of the bearing.
