Attic Truss With Heel

Below are some diagrams to help illustrate the measurement points.

Attic truss with heel. Ventilation eave baffles if needed for air flow. 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. 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.

Easy to build with. Girder trusses are designed to carry additional loads other than standard roof loads. A truss with the same pitch and heel on both sides and a peak at the center is called a common truss. Raising the truss higher has two big advantages.

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. Builders don t need special tools or know how to build with them. Standard heel typical truss heel height is about 4. A raised heel truss is identical to a conventional truss except for one difference.

One of the most important measurements needed to match an existing roof is called the heel height. Raised heel trusses 9 1 4 to 15 1 4 inches in depth. Raised energy heel typical truss heel height is about 12 but may be designed to most any height per the building designer specification. Building is designed in accordance with the irc.

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.
