While a roof truss is a major roof construction, they come in a number of different types and configurations. Each option has its own way of dealing with external forces acting in the node area. The key differences among the roof trusses are in the way they are made and the distinct features they have. Most of them can be customized and choosing one really boils down to you and your home design. But it helps to know first how each of the common options looks and works to decide which one suits you best.
King Post Truss: usually, a king post truss is made using timber but it can be made utilizing a combination of wood and steel, depending on the building structure and the architecture behind it. This roof truss configuration typically spans up to 8 meters high, making it suitable for different types of homes, but especially the smaller houses.
Queen Post Truss: this roof truss offers a simple design, which makes it a great option for different building structures. Among the various roof trusses, queen post is specially designed to provide reliability and versatility which you can use at any time of the year when you’re constructing your home.
Scissor Roof Truss: inherent to its design, scissor roof truss provides more space in the attic as the ceiling is vaulted. It also does not require plenty of support from load-bearing walls and beams but it offers poor energy efficiency due to the lack of enough space for proper insulation. It is commonly found in most cathedrals.
Raised Heel Roof Truss: compared with scissor-type roof truss, the raised heel is more efficient by providing excellent insulation. This design also offers you an amazing system for structural support to your roof but it may need some extra materials to achieve the best results. This makes it a bit more expensive than other configurations of roof trusses. But this little added cost can be compensated in the long run with the savings you can get with lower energy bills.
