Roof Truss With Heel

Raised heel trusses can be installed in a single day.

Roof truss with heel.

When insulation is compressed its r value is reduced. Below are some diagrams to help illustrate the measurement points. A raised heel truss is identical to a conventional truss except for one difference. Other than roof pitch and span the most importand measurement need to match an existing roof is called the heel height.

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. Raised heel trusses also known as energy heel trusses deliver cost effective energy performance especially when used with continuous plywood or osb sheathing. Getting your home build under a roof earlier can prevent moisture damage.

The raised heel provides additional space for cheaper attic insulation and for the full depth of insulation to be extended right to the outside of the top plate. Simply it is the thickness of the truss or rafter measured from the outside of the wall from the top of the top plate to the underside of the sheathing. How raised heel trusses save you money. When improved insulation is combined with efficient air sealing and adequate attic.

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. With a raised heel truss you have enough space to utilize cheaper insulation methods such as blown cellulose. Raised heel trusses are engineered utilizing advanced design and manufacturing. Combined with a properly designed attic ventilation system and some well placed air sealing a roof framed with raised heel aka high heel or energy trusses reduces the temperature and pressure differences between the conditioned living space below and the unconditioned attic area thereby reducing thermal transfer or heat loss between those spaces.

Framing with raised heel trusses and continuously sheathing exterior walls improves structural and energy performance and offers many savings that benefit both the builder and the homeowner. Truss heel height the vertical depth of the truss at the outside face of the bearing. One of the most important measurements needed to match an existing roof is called the heel height.
