Truss Framing Details

SPECIAL DESIGNS- attic trusses add extra living space at small cost. The Vault takes many forms with supports at various locations to give a raised effect in a portion of the span.

Mansards and stubs are two more of the thousands of other truss configurations available to meet special design applications

Important Information about Ceiling / Partition Separation

Ceiling/partition separation has occurred occasionally in wood framed buildings causing gaps in the drywall along the comer between the ceiling and the partition walls. Ceiling/partition separation is caused by a combination of material characteristics and environmental conditions, and can be prevented by using correct and well-established construction practices.

Causes for Ceiling/Partition Separation

  1. Bearing and support settlement
  2. Shrinkage of framing lumber and headers due to drying of lumber
  3. Raising (arching) of the roof trusses
  4. Excessive deflection of floor below the partition

 

Recommendations to Avoid Ceiling/Partition Separation.

 

  1. Make sure that foundations are of the right size and properly placed and on suitable bearing material. Request an inspection by a professional engineer if in doubt.
  2. Provide adequate structural supports under all partitions.
  3. Use dry lumber for headers and load bearing structural framing. Prevent exposure of these structural components to rain.
  4. Protect trusses from exposure to rain during extended periods of storage.
  5. Do not ventilate kitchen and utility vents into the attic space.
  6. Provide adequate ventilation from the attic space to the outside.
  7. Insist that the drywall contractor use floating comer construction. The ceiling must be secured to the top plate of
