What type of timber is used for roof trusses?
Correspondingly, why is timber used for roof trusses?
Wood or Timber roof trusses are widely used in USA, Canada and other countries because of its advantages over other trusses, as it offers great flexibility in plan layout. The high strength-to-weight ratios of timber trusses permit long spans, offer greater flexibility in floor plan layout.
Likewise, what is the maximum span of a roof truss? Trusses can span up to approximately 90', although very long truss spans are more challenging to deliver, erect, brace and install properly. While longer trusses may be “wobbly” as they are lifted off of the ground and onto the bearing walls, once they are properly braced, the truss system is extremely strong.
Besides, what type of wood is used for rafters?
Rafters are usually made of Pine or Cedar. For longer span rafters, building materials manufacturers have created LVL (Laminated veneer lumber) rafters that can be 2–5 times longer than typical wood rafter. In US, most wood rafters have maximum length of 20 feet.
How much is a wood truss?
Trusses run anywhere from $30 to $400 each. If you know the board feet, you can estimate between $0.60 to $1.50 per board foot. Large and complex roofs need specialized trusses at a higher price.
