Oak Roof Trusses

Exuding elegance, style and character an Oak roof truss or feature truss adds the “wow” factor to any new build or extension.

An oak roof is formed with trusses and purlins which are the visible and dominant feature transferring the weight of the roof onto the walls.

A Feature Truss adds the style and “wow” but does not necessarily form part of the structure.

All Oak Trusses come in many different forms, performing different functions and creating different looks within your living space.

Types of Oak Truss Design

King Post Truss

A classic functional oak truss

  • The king post is the large central post running vertically up to form the apex of the truss, it can incorporate weight bearing struts or not.
  • The tie beam carries the weight transferred by the king post easily as it is working under tension.
  • Often employed at the gable end of the building where cladding or glazing is to be installed or where it is unlikely that a second floor would be required.

Queen Post Truss

  • Queens posts trusses have a pair of symmetrical posts on either side of the truss linking the principal rafter to the tie beam. Often these are positioned in-line with a purlin run to transfer the load down to the tie beam.
  • They can be used with or without a king post or collar.
  • Queen posts are traditionally curved, but this is not compulsory.
  • Queens positioned towards the outside of the truss will create the perfect opportunity for usable space in the attic.

Half or Mono Truss

  • As the name suggests this is one side of the truss.
  • Often incorporating half the king and queen posts if the span requires it, or that style is desired.
  • Half trusses are used for lean-to style extensions or garden rooms.

Understanding an Oak Truss

  • All roof trusses perform the same functions, but in different ways:
  • The principal rafters set the pitch of the roof, carrying the ridge beam and purlins which in turn take the weight of the rafters and tiles.
  • Tie beams connect the bottom ends of the principal rafters, tying them together and preventing them from spreading or pushing the walls out.
  • King posts transfer loads from the ridge to the tie beam.
  • Queen posts transfer loads from the centre of the principal rafters to the tie beam, they are particularly effective fitted underneath a purlin.
  • Collars join the principle rafters at a higher level to help to stop them from spreading.

In days gone by carpenters would use their experience to choose section sizes and joint details to appropriate for the structures they were building. Today you will need to have your frame design signed off by a structural engineer, they will specify section sizes and timber grades. Timberpride will supply your frame to these agreed dimensions with CE certificates of structural performance to THa, THb, Th1 and TH2, D30 and D40 in accordance with BS 5756. Not as romantic as the old days, but probably more reassuring!tly the same job, just a little cheaper!
