When it comes to structural frameworks for supporting roofing systems, timber roof trusses are one of the best in the construction industry. Not only are they capable of providing an outstanding level of support for roofs, but they also offer a number of advantages that include durability, affordability, design versatility, and energy efficiency.
Because of its several advantages, opting to use a timber roof truss over other conventional options is the easy part during a building project’s planning phase. The difficult part is when you have to select a specific timber truss design style that ideally suits your taste and also meets specific purposes and conditions.
To help you determine which type of timber roof truss is the right one for you, we will list down the most common types and discuss their design styles.
But before we get started, always keep in mind that you should not get fixated on a particular design, because the style you end up selecting is always impacted by building practicality. Even if you ask the roof trusses manufacturers around your area, that’s what they’ll tell you. Anyway, let’s start.
Scissor trusses are typically used – and found – in the ceilings of cathedrals due to the construction convenience it brings for such structures. Unlike other styles, the scissor truss doesn’t rely that much on bearing beams, and its lower chords are sloped inwards instead of horizontally. When used in a home, the scissor truss, together with its exposed wooden beams, can deliver an incredible rustic look and feel to any residence.
It’s a given that a timber roof truss is already energy-efficient enough to benefit structures, but the raised-heel truss ups the ante by providing an even greater level of energy efficiency. This truss type is able to do that because it is made of engineered wood trusses that are fitted with a heel, in which the perimeter wall plate intersects with the bottom chord. This creates extra space that can be used for more insulation, hence its improved energy efficiency.
The king truss is a simple type of truss that features common vertical support connected to two angled supports. Due to the straightforward nature of the king truss, even a novice craftsman can build it without any trouble. The issue, however, lies in the fact that its usage is entirely limited to roofs with a short span.
If style is your thing, then the queen truss is suited for you. With its mix of European- and craftsman-style design, the queen truss looks as wonderful as its name sounds. When it comes to functionality, it has an opening that spans longer than the king truss, allowing for more storage space. Also, the queen truss uses two central supporting posts.
Parallel Chord Roof Truss
The parallel chord roof truss is also commonly used in cathedral ceilings for the same reason as the scissor truss. But the difference between the two starts with this truss type’s costliness due to it needing steel members for bracing, which can contribute to decreased energy efficiency. However, despite the disadvantages associated with a parallel chord roof truss, it’s still a fairly popular option because of the practicality and visual appeal of its simple lines.
