How to Choose the Right Type of Truss for Your New Home Construction Project
If you are engaged in a home construction project, you know that there are a number of critical components that provide the building with its ability to stand up against the elements and to last for a long time. In certain parts of Australia, homes have to be built to withstand the massive forces associated with tropical cyclones as well, and in this case the chosen materials will be even more important. In particular, the roof has a job of protecting the home through all situations and is typically held in place by trusses underneath. What are roof trusses, and what options are available for your new build?
Taking the Strain
In Australia, slates or tiles are favoured products for new roof installation, and the trusses represent the structural beams and supports that can accommodate the associated weight. A roof truss is typically made from either steel or timber and is bolted together in a certain fashion to provide the best support to the roof above. Usually, the trusses are designed and built elsewhere, before being brought to your site for installation, as this will reduce the amount of job time.
Over the years, a number of designs have materialised, enabling tradesmen to install a variety of different truss configurations. It's best to stick with one of the more favoured designs which have stood the test of time, whether you are building from scratch or are in the process of renovation.
The most popular style today is called the "king post" truss, and it can withstand a lot of pressure and tension for long periods of time. This durable option stretches two large rafters above the king post, which is placed in a vertical, central position and then attached to a tie beam. Alternatively, you could choose the queen post, which uses two central posts rather than just the one, and this is particularly useful in larger properties, which call for an expansive span.
If you want vaulted ceilings in your home to create an increased perception of space, then you may want to consider the raised tie truss. This type of design allows the ceiling to be elevated beyond the wall plate height, while providing the needed strength and durability of the other versions.
Making Your Calculations
Have a word with your designers and architects to see what type of roof truss would be perfect for your upcoming project. Make sure that you also check with your roofing suppliers, to add the necessary costs into your budget.
