Vaulted roof structure.

In a common truss design sloping top chords function just like rafters in conventional framing and horizontal bottom chords fill the role of ceiling joists. Homeowners often want to create a vaulted ceiling design. Vaulted ceilings can be constructed by either stick framing which means attaching each joist and rafter individually or by setting roof trusses that come engineered from a truss manufacturer with. Engineered roof trusses may be designed to create a vaulted ceiling while still providing sufficient support for the roof s weight.

Naturally this truss is used in buildings for creating a pitched roof. Exposed building materials can add interest. It is more expensive though. A vaulted ceiling in new construction is no more complicated than standard framing although it does require special roof trusses which are usually built off site.
