Frame Truss FAQs: Your Top Questions Answered


Installing floor trusses for a new home’s framework has many benefits. They can hold weight for a long time due to their firm structure and are by far the strongest option for a home’s infrastructure. But with such a complex web of wood and metal, you might be wondering how someone even begins to install them. In this article, we aim to break down all the processes involved in the installation of floor trusses. Read on to find out more.

What are floor trusses?

timber floor trusses are wooden bars that are fitted together with metal joints. They make installing plumbing and electric works much easier than other forms of frameworks and are the strongest of all types. They feature several components. These include the top and bottom chord, alongside smaller wooden parts which are placed in a triangular formation between the two main chords. This makes the structure able to withstand hefty loads and gives it a deflection factor, which means that it can move slightly to avoid any concentrated stress on one area of the truss.


The trusses will arrive bundled together, each one marked with either a number or letter which indicates where it should be placed during assembly. The pack will come with an attached blueprint that illustrates this. After the builder has checked that all of the pieces are present in the package, they can begin the task. Layout typically calls for 16-inch spacing between the trusses, but this can be more if your house is larger or heavier than usual.


This stage is crucial, and where new homeowners need the help of professionals. Assembling of the trusses can then be done on the ground before being moved to their designated place. This is done by following the enclosed instructions the builders are provided with, and by following the previously mentioned numbers on each piece. After this, floor trusses must be attached to multiple bearers or beams to keep them upright. This can be done with framing brackets. This is what is known as bracing. After this stage is completed, flooring materials such as plaster or particle board can then be laid in an equal dispersion over the trusses, which will take most of the weight and ensure that any weight placed on the infrastructure in the future will not break the wooden timber. The builders will now be able to walk around on the trusses freely without the potential to cause damage. All that is left to do is implement cladding and strongbacks for extra support, which can be nailed to the side of the truss. These will help to give it more strength for future use.
