Attic Truss With Heel

Raised heel trusses 9 1 4 to 15 1 4 inches in depth.

Attic truss with heel.

Girder trusses are designed to carry additional loads other than standard roof loads. Below are some diagrams to help illustrate the measurement points. Standard heel typical truss heel height is about 4. Raised energy heel typical truss heel height is about 12 but may be designed to most any height per the building designer specification.

A raised heel truss is identical to a conventional truss except for one difference. Building is designed in accordance with the irc. 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.

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. Ventilation eave baffles if needed for air flow. It greatly simplifies attic ventilation and it leaves ample room for insulation above exterior wall top plates.

More importantly the raised heel provides the opportunity to increase energy efficiency to meet new energy code requirements. One of the most important measurements needed to match an existing roof is called the heel height. Raising the truss higher has two big advantages. Raised heel trusses are installed the same as conventional trusses.

A truss with the same pitch and heel on both sides and a peak at the center is called a common truss.
