Their functions are similar to rafters.

Roof rafters and ceiling joists.

For example cathedral ceilings built with 2x12 rafters have space for standard 10 inch batts r 30 and ventilation. In unfinished space an attic insulation is typically laid between the joists. 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. Ceiling joists can be on both low sloped roofs and high sloped roofs and help to prevent racking and spreading of your rafters or walls which could lead to sagging.

Also available for the android os. This board forms the bottom member of each rafter and of course the ceiling of the space below. A structural ridge is the standard alternative to ceiling joists. The are similar to trusses in this regard.

Span calculator for wood joists and rafters also available for the android os. Ceiling joists are horizontal members used with rafters and roof joists. Floor joist span use this table to determine the maximum lengths of floor joists based on species of lumber joist spacing and joist size. Span tables for flat roof joists to bs 5268 7 2 imposed loads of 0 75 kn m for maintenance and snow load are applicable where there is no permanent access no fixed ladder or staircase and most areas where the altitude does not exceed 100 metres refer to bs 6399 3.

They may carry ceiling loads. They are important load bearing structural elements. 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. Cathedral ceilings must provide space between the roof deck and home s ceiling for adequate insulation and ventilation.

Roof joists may span continuously from one side of the house to another or may be supported on an interior bearing wall. Joists are traditionally made from timber. The joists might then be covered with osb or plywood to form an attic floor for storage. In this design the tops of the rafters attach to a load bearing ridge beam that runs along the length of the roof.

Similarly ceiling joists are the planks of wood that create the flat surface of your attic floor or top story ceiling. This can be achieved through the use of truss joists scissor truss framing or sufficiently large rafters. Roof rafter span use this table to determine the maximum lengths of roof rafters based on species and grade of lumber spacing dimensions load and slope.
