What's your take on a roof that saves you money at the end of the month? In this era, you don't have so many options that can save you money when it comes to building materials. However, roof trusses from a company like Prefab Technology Pty Ltd can save you money in the long term. They are the best opportunity for keeping your energy bill in check and making sure that you don't run your vents using too much electricity. During installation, insist on raised heel trusses for your roof. It might cost a few extra coins during installation, but all this is worth it considering the amount of money you will save on artificial ventilation. Here is all the insight you need regarding raised heel trusses:
Defining a Heel Truss
The name "heel" suggests a joint or intersection where something changes direction. Well, that's the same thing for your home's roof. The heel is the point where the diagonal truss sections meet the bottom chords that bear the weight of the building. Literally, the diagonal top chords sit on the bottom bears. Raised heel trusses refer to a scenario where your roofer lifts or increases the distance between the top diagonal chords and the bottom load bearers.
Raised heel trusses are the one place you must get right if you want to make the most of them. Typically, your builder can raise your heel truss up to one foot of the bottom chord of the roof. Putting too much height on it increases the chances of damaging your roof during inclement weather. Strong winds and storms can mess it up.
It's judicious to use the same kind of material for the truss and the raised heel. It improves the structural well-being of your roof. For instance, a steel raised heel goes well with steel roof trusses. If you opt for a material such as wood, you might create lines of weakness because these materials do not have the same tensile strength.
How They Work
Raised heels trusses improve energy efficiency in several ways. First, they increase the volume of the attic space, providing more room for air to circulate. This enhances the ventilation of your indoor space by cutting transfer and regulating temperatures desirably. The raised heel truss minimises the temperature and pressure difference between your indoor space and the attic. Lastly, a spacious attic allows for the construction of multiple natural ventilation mechanisms. You will not experience ice dams during winter because of the stable temperature in your attic.Share
