Attic truss with heel.

A raised heel truss is identical to a conventional truss except for one difference. Standard heel typical truss heel height is about 4. Truss heel height the vertical depth of the truss at the outside face of the bearing. 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 heel trusses 9 1 4 to 15 1 4 inches in depth. More importantly the raised heel provides the opportunity to increase energy efficiency to meet new energy code requirements. Building is designed in accordance with the irc. A truss with the same pitch and heel on both sides and a peak at the center is called a common truss.

One of the most important measurements needed to match an existing roof is called the heel height. Easy to build with. Builders don t need special tools or know how to build with them. Ventilation eave baffles if needed for air flow.

Raised heel trusses are installed the same as conventional trusses. Raising the truss higher has two big advantages. Girder trusses are designed to carry additional loads other than standard roof loads. It greatly simplifies attic ventilation and it leaves ample room for insulation above exterior wall top plates.

Raised energy heel typical truss heel height is about 12 but may be designed to most any height per the building designer specification.
