A roof truss is a pre-fabricated structure with straight pieces that form a series of triangular sections to support the load of a roof. They allow flexible placement of interior walls and span the outer walls of a structure. They are also an essential component to create a structurally sound home or building.
While the members of the triangles are placed under tension and compression brought by the weight of the roof, their robust nature keeps them from bending.
Plus, roof trusses can be engineered for all kinds of structures – from a residential home to a commercial building – so the short answer to the title of this article is already mentioned above.
But if you are seeking a longer, more detailed answer, then keep on reading.
Characterised as being cross-braced into a stable and rigid unit, timber roof trusses were a medieval development that was meant to replace rafters – which are also a structural component for roof construction that has been around for centuries.
Back in the old days, roof trusses were considered a huge upgrade over traditional rafters due to the tendency of the latter to flatten under gravity and collapse from horizontal movement – both are two things that are far less likely to happen with a roof truss. Even up until now, that fact remains true as the majority of the homes being built today use pre-manufactured roof trusses as opposed to rafters.
Roof trusses are manufactured off-site and can be custom-made to meet the unique specifications of a construction project, sparing homeowners and contractors from the stressful experience of jumping from supplier to supplier just to look for the exact components.
The two most popular types of roof trusses are timber and steel. However, many people prefer to use timber roof trusses more due to the number of benefits offered by sustainable material. Steel is used for structural support on softer timbers or wide-spanning trusses, but it’s called a Gusset plate or a truss connector plate.
The two most popular types of roof trusses are timber and steel. However, many people prefer to use timber roof trusses more due to the number of advantages associated with sustainable material. But even in timber roof trusses, steel (called a Gusset plate or a truss connector plate) plays a crucial role as it is used for structural support on softer timbers or wide-spanning trusses.
Let’s have a quick look at the advantages of a timber roof truss:
- It is Eco-Friendly in So Many Ways
Timber is a renewable construction material that releases oxygen into the environment and eats up lesser energy to process.
- It is a Cost-Effective Option
Timber roof trusses are so easy to install that heavy equipment isn’t needed to put it in place, reducing the total amount of labour costs. They are also more affordable compared to other trusses.
- It Offers the Durability That a Structure Needs
Timber roof trusses that are manufactured according to the right specifications are able to provide the required structural integrity of a house or building.
- It is Compatible with Other Structural Components
The versatility of a timber roof truss allows it to be amalgamated with other structural components or linked to other trusses.
- It is Energy Efficient
The thermal properties of other framing materials are peanuts compared to what timber frames and trusses have. While the material itself boasts natural insulating capabilities, the large cavities they create during installation are also easy to insulate, which further amplifies their thermal properties.
