7 Most Common Types Of Roof Trusses: Best Support For Your House
The term “roof truss” might not sound foreign to you at all if you are in the process of constructing your own home. They have the appearance of a supporting structure that is lifting the entire weight of your roof. However, are you aware of the various kinds of roof trusses that are available? We bet most don’t.
In this article, we will cover everything you need to know about this practical structure, so make sure you don’t miss it! Continue to read the book!
7 Popular Types Of Roof Trusses
In most cases, we can classify roof trusses into one of two primary varieties: flat roof trusses or pitched roof trusses. Nevertheless, we are going to delve even further into the topic today by dividing them up into eight distinct types so that you can gain a better understanding of how each one might be utilised.
1. King post truss
A king post truss is the best choice to make when your spans are restricted to between 5 and 8 metres in length. This type of truss structure is commonly used in the lifting of extensive roofs, like those found in garages and barns. The beauty of the whole thing contributes significantly to its notoriety.
The initial design of the house is improved by the addition of these trusses because they have a minimalistic appearance, with simple lines and narrow bridges. Additionally, the production of aircraft makes use of its design. King post trusses are used in aeroplanes to carry the cords and lift the wings of the aircraft.
2. Queen post truss
The primary distinction between a queen post truss and a king post truss is that queen post trusses have two wooden poles that serve as supports for the entirety of the frame. King post trusses, on the other hand, do not have these poles. These poles are queen posts.
A queen post truss is an option worthy of consideration for those whose span falls between 8 and 12 metres. In contrast to the queen post, which distributes the total weight among two poles in equal measure, the king post must bear the entire weight of the roof on its own. This design makes these trusses easier to understand and lighter in weight, both of which are benefits of the structure.
3. Mono-pitch truss
The use of a mono-pitch truss is ideal for people who are looking for a truss that will work for their one-sided roofs, also known as lean-to roofs.
4. Double-pitch profile truss
The double-pitch profile truss is the type of truss that you need if you are looking for one that is capable of being both symmetrical and asymmetrical at the same time. Its design is more complicated than that of other types, so you will most often find it in commercial buildings or homes that have very specific roofing requirements.
5. Fink truss
The initial stage of development for fink trusses involves the combination of webs in the shape of a V. You can see that the chords at the top angle down away from the centre, creating a small V shape in the process. Fink trusses typically rely on straight-side frames; as a result, they can transfer the weight’s loads to other pillars in an effective manner.
There are also double fink trusses and fan truss variants of the standard fink truss.
- Double fink: The original fink had a pattern in the shape of a V, but the double fink makes use of webs in the shape of a W to provide superior support for the roof.
- Fan: The primary distinction between these two types of structures is that the original webs of fink trusses have been modified to take the form of a fan and extend outward from the bottom joints.
6. Vaulted truss
You can create a one-of-a-kind roof design with the help of a vaulted truss. If you have a thing for cathedral ceilings, you won’t be disappointed with the truss system that we have here.
7. Raised tie truss
If you adore the idea of a vaulted ceiling but find the process of adjusting the scissor trusses to be too taxing, raised tie truss can be the solution for you. The lowest chords of it ascend, so establish a level surface for your vaulted ceiling.
4 Steps To Determine The Suitable Truss For Your House
There is a possibility that some computation will be required to find the ideal truss for your property. To determine which truss you should use, please complete the steps outlined above:
- Determine the contour of your roof as well as any other necessary criteria such as the span of the truss, the loads, etc. If you choose to purchase pre-made trusses, you may look up additional information by consulting the product’s information at your convenience.
- After that, choose the trusses that you like most while simultaneously calculating the optimal span that works best with your design.
- After that, measure your design and examine how it compares to the span of the truss you selected. If the numbers do not correspond, the following equation can be used to determine an appropriate new distance (A’):
New distance A’ = (span of the standard truss)²(design span)²x (standard distance between trusses A)
- Finally, calculate the load that will be placed on the roof by your design and contrast it with the load that will be placed on your preferred truss. If the numbers don’t add up, you’ll need to figure out a new distance (A’) to make sure the loads are balanced:
Truss new distance A’ = load of standard design loads (standard distance between trusses A)
Roof Rafters Vs. Trusses: Which Should You Choose?
The vast majority of people are unable to distinguish between trusses and rafters. Now, we’ll explain the differences between them based on the functions that they serve specifically.
In the following scenarios, you would want to make use of trusses:
- You don’t like the idea of having an attic space.
- You want a vaulted ceiling that is the industry standard.
- It’s simple to get to your location.
- You want to keep the expense of the design to a minimum.
In the meantime, rafters are your best option in the following scenarios: You
- Want to have the most comfortable living environment possible.
- You prefer a vaulted ceiling that is only slightly sloped in one direction.
- It is really difficult to get into your construction area.
That is all the information we have for you at this time. We are confident that this post has provided an in-depth explanation of the eight most prevalent types of trusses. What are you holding out for exactly? Purchase the ideal truss for your roof so that it can look its best.
