Unlike traditional framing, roof trusses are built from shorter lengths of lumber, and are therefore lightweight and cost effective. They also provide structural support and span large distances. Roof trusses can be designed and built in a number of different ways. It is important to work with an experienced architect or structural engineer to determine the best design for your home.
What are the 3 types of trusses?
One of the most common roof truss design is the pitched truss. It is characterized by a triangular shape and parallel top and bottom chords. This type of truss is most often used for roof construction, but can be used for floor applications as well.
Cathedral trusses are used in high ceiling buildings. They are reliable, durable and aesthetically pleasing. They use steel members for bracing. They also have a flat interior that allows for mechanical units and other roof-mounted units.
Another type of roof truss is the hip truss. These are ideal for windy areas and offer great support. They are also architecturally pleasing.
Another common roof truss is the king truss. This truss is made up of two sloping rafters joined at the top. This truss is structurally sound for spans up to 16 feet. It has a simple design and can be complemented by two additional braces.
Another common roof truss design is the gable truss. Gable roofs include the fan truss, the queen post truss and the Howe truss. These are all variations on the king truss.
