Product Information

Trusses may be described as the skeleton of a roof. They are a critical part of the roof as they provide structure, shape, stability and support.

In home construction, wall framing includes the vertical and horizontal members of exterior walls and interior partitions. These members (or studs), wall plates and lintels function as the nailing base for all covering material. The frame supports the upper floors, ceiling and roof.

Frames and trusses in Sydney (or wherever you are building your home) work together to make a house safe, durable and stable.

Examples of Trusses

There are many types of roof trusses used in residential building construction. Some of these are:
  • Coffer or tray truss: This has a vertical interior ceiling detail that's sloping or non-sloping. It is usually applied for aesthetic purposes as it adds height as well as a focal interest to a ceiling. It is ideal for use in the dining room, kitchen or living room.
  • Barrel vault truss: As its name suggests, the barrel vault truss has a barrel-shaped ceiling. It is a decorative truss that can add volume and keep a room cool. It also known for having a low-maintenance drywall, making it great for use in cellars.
  • Clear story truss: This type of truss is actually a high wall set between two sloping sides. It includes a band of narrow windows that let in light and fresh air, helping to make energy-efficient buildings.
  • Double cantilever:A double cantilever has two horizontal beams extending beyond the load. They are fixed at one end and serve to add height to a structure. Double cantilevers are popularly used in some commercial buildings, like grandstands exposition venues.
  • Double pitch truss: As indicated by its name, a double pitch truss comprises two sets of different sloping sides usually placed at the front and back of each other. These trusses are used for gable roofs.

There are other types of trusses not listed here. In fact, there are about 30 different types of roof trusses. The type of truss you choose would be based on your roof design.


1. Would I be able to set up trusses on my own or should I get a contractor?
If you have the training and knowhow to put them up on your own, you may do so. With a contractor, you’re guaranteed a professional job. However, this doesn’t mean that it’s something you can’t handle. What’s important is to ensure you know exactly what to do and have the confidence to do it.

2. Aren’t trusses expensive?
The cost of a truss depends a lot on the size, style, function (whether it is decorative or structural) and the kind of wood used. Just note that more complicated truss designs (e.g. scissor truss or hammer beam truss) usually cost more as they require more labour and materials.

3. What’s the difference between a frame and a truss?
In house construction, a truss is a part or section of the roof framing. The frame itself comprises the walls, top plates and bottom plates. A truss usually has a top chord, bottom chord and intermediate members. These are usually set diagonally to form triangles which, in turn, give the truss component strength. A frame in house construction provides support and may comprise columns and beams or wood or light gauge metal studs.

Whether you plan to handle the frame and truss work on your own or work with manufacturers of frames and trusses in Sydney, make sure the materials you use are engineered to Australian standards
