Material Used To Construct A Raised Heel Roof Truss

A howe scissors truss is so called because its appearance resembles that of an opened pair of scissors.

Material used to construct a raised heel roof truss.

The design helps prevent ice dams which occur at the eaves of conventional roofs where insulation at the wall and truss intersection is thinnest and is often compressed reducing its r value. The most common types of roofing systems used with flat roofs are rubber roofing systems. Naturally this truss is used in buildings for creating a pitched roof. This results in walls with improved resistance to lateral forces like winds or seismic activity.

Its bottom chords join together at the apex creating a pitched or vaulted ceiling. With conventional trusses a builder would have to use a spray applied foam insulation on the roof rafters to achieve the same values and meet code says dave ford a designer at maple valley truss in prudenville mich. Standard trusses limit the amount of insulation that can be installed which reduces the efficiency of your building envelope or depending on the energy code in your area requires you to utilize foam insulation. The value of an energy truss system is enhanced by the fact that it allows builders to use fiberglass batts the most affordable insulation option for the attic floor.

We use a product called accu vent to maintain the soffit to roof ridge vent ventilation path and contain the cellulose or fiberglass blown in insulation. Using raised heel trusses allows you to increase the amount of cheaper insulation used such as blown cellulose or fiberglass batts. Gable roof the gable is roof is typically triangular forming an inverted upside v shape. Our passive solar house designs typically have a 4 roof overhang and we use bruce dana perforated metal soffit material that is fastened directly to the 2x6 truss tails.

We ripped 4 x8 plywood in half and notched it where the bottom chords overhung our walls. It is basically made of two sides with a middle gap called a gable. Raised heel roof trusses sometimes called energy trusses are a great way to take advantage of the energy codes that allow lower attic insulation r values when full depth insulation extends to the outside edge of the top plate without compression. We are actually mixing metal strap bracing with 1 2 plywood sheathing.
