WOOD FRAMING

WOOD FRAMING
2

• Wood framing include interior and exterior walls
  both load bearing and non-load bearing.
• Wood used in building structures can be studs,
  bottom and top plates, headers, cripples, sill
  plates, cripple studs, floor joists, sheathing,
  backing, stairs and roof rafters.

The materials list

• Conventional lumber is sold in rounded off
  measurements but are actually smaller than what
  the measurement says. Ex
• Common Name Actual
• 2x4 1 ½ x 3 ½
• 2x6 1 ½ x 5 ½
• 2x8 1 ½ x 7 ¼
• 2x10 1 ½ x 9 ¼
• 2x12 1 ½ x 11 ¼
• Anything the is 1x common name is actually ¾ x
  actual.

Conventional lumber cont
SIZE USE
2 X 4 Interior wall, Exterior walls (depending), stick framing roofs
2 x 6 Exterior walls, fascia, framing roofs
2 x 8 Used in rafters for roof trusses
2 x 10 Window and door headers
2 x 12 Can be used as support beams for wall/window opening depending on width (bay windows, garage doors)

Other Framing materials

• Sheathing
• Plywood
• - made from spruce,pine or fir (SPF). Comes in
  different width that are used for different parts
  of constructions.
• 3/8 roof sheathing
• ½ - side sheathing
• 5/8 ¾ - flooring (tongue and groove)
• OSB
• - Oriented strand board (OSB) is an engineered
  wood panel product made of resin-bonded wood
  strands or flakes. Also known as chipboard.
• -used for exterior sheathing, used for some
  types of floor joists.

Floor Joists

• Can be 1 of three
• designs
• 2 x 12 with cross bracing every 16 inches

I - joists

• - I joists are made with laminated or solid wood
  beams, with OSB glued and placed in the middle
  for support.
• - B I Joists lightweight construction, ease of
  handling, strength and long spans result in lower
  overall labour and material costs compared to
  solid lumber.
• - These joists prevent splitting, warping,
  twisting, bowing, and squeaky floors (when
  installed properly)

Floor Truss System

• Considered to be the Cadillac of floor systems.
  Because of their design possibilities their span
  capability allows them to create more spacious
  rooms free of awkward columns.  Bonus rooms over
  garages can be built without the need for support
  beams and columns where vehicles normally park. 
  Entertainment areas on all floor levels can be
  more spacious making them more usable.

Roof Trusses

• Roof trusses are engineered by companies who can
  fabricate truss systems to any pitch and span
  depending on building design.
• Preferred over stick framing. Truss webbing held
  together by engineered gusset plates (metal
  connector plates)

Pre-engineered Beams

• LVL is intended to provide a structural function
  only. The surface finish is usually of low
  architectural quality with rough glue lines often
  visible. Where required products can be fine
  sanded and painted to give a similar finish to
  solid painted timber.
