Framing Your House (cont. p. 7)


Joists and Trusses


A joist is a horizontal structural unit that spans the distance between walls, columns, or beams for the purpose of supporting floors, ceilings, or roofs.

 

Trusses are pre-manufactured structures consisting of triangular units.


They may serve as roof support or as floor and ceiling trusses.


Trusses can be designed to fit virtually any roof design.


Trusses can accommodate whatever gables, hip, or valleys make up the overall roof design.

  

My experience is that trusses are most cost-effective on a simple gable roof.

They become more expensive as roof complexity increases.



Trusses have advantages.  They have excellent strength and spanning capacity.

They can be installed more quickly than a “stick-built” roof.


These manufactured trusses provide an instant vaulted ceiling.

It is unlikely that your original house plan was designed with trusses in mind.

Many lumber companies can take your plan and design and build trusses customized to fit your house plan.

If your lumber company doesn’t do this, they should be able to refer you to a company that does.
