Roof Celine Joists

They are used to support a ceiling above or the floor below.

Roof celine joists. Ceiling joists of the first floor of a two story structure often serve as floor joists for the second floor. Joists are traditionally made from timber. A structural ridge is the standard alternative to ceiling joists. These span tables list allowable ceiling joist spans for common lumber sizes based on what design load scenario is applied.

Ceiling joist loads ceiling joists are sized based on one of two tables found in the code. These joists are below the beam and are tied to it by 2x4. The roof joist is what makes up the ceiling of a home. They are nominally 2 inches thick actual width usually 1 1 2 inches and come in a variety of widths from 8 to 12 inches.

Joists are the parallel horizontal beams that run across an open space joining opposite walls in a building to support both the ceiling below and the floor above. The joists are horizontal pieces of lumber that span the distance from one side of the home to the other. The ceiling joist 2x4s are running at right angles to the beam and rafters across the 12ft span of the room. Ceiling joist spans for southern yellow pine douglas fir and eastern spruce joist span tables use these tables to determine lengths sizes and spacing of ceiling joists.

We were told that the joists are not providing structural support and were merely for affixing the flat ceiling.
