Are you wondering what a roof truss<\/a> is? If so, you\u2019ve come to the right place!<\/p>\n

In this article, our\u00a0prefabricated wood structure<\/a> experts\u00a0will tell you everything you need to know about roof trusses.<\/p>\n

We\u2019ll pay particular attention to timber (wood) roof trusses, as they\u2019re one of our company\u2019s specialities.<\/p>\n

Roof truss definition<\/h2>\n

Prefabricated roof trusses are triangular frames composed of softwood lumber<\/a> in various lengths and sizes. Their triangle structure makes their frame more rigid and provides support to the roof without requiring large planks of wood.<\/p>\n

The pieces of wood are usually assembled with metal connectors made of galvanized steel sheets but can also be reinforced with nails and braces.<\/p>\n

Manufacturers use advanced architectural and engineering software to custom design the timber trusses according to the construction plans. That\u2019s why it\u2019s so important to use accurate measurements.<\/p>\n

Prefabricated structures have now replaced traditional wood frames that are built directly on site. They are widely used in residential, commercial and agricultural construction.<\/p>\n

Depending on the region, roof trusses are also called: frames, industrialized frames and even timber frame rafters<\/a>. Be careful though: these expressions do not always mean the same thing.<\/p>\n

Types of roof truss<\/h2>\n

As we previously mentioned, manufacturers use computer tools to design a wide variety of timber truss models, adapting their size to each project.<\/p>\n

By producing timber trusses in factories, manufacturers can create complex geometric structures quickly.<\/p>\n

The most popular roof truss models are:<\/p>\n

Common roof truss<\/h3>\n

\"\"<\/p>\n

Common (or \u2018standard\u2019) roof trusses are reliable and versatile. They span up to 72 feet (22 metres) and their simple triangular design makes them easy to integrate into many types of construction projects.<\/p>\n

Barn trusses<\/h3>\n

\"\"<\/p>\n

Barn trusses are ideal for erecting agricultural buildings or residential buildings with a barn-like architecture.<\/p>\n

Attic truss<\/h3>\n

\"\"<\/p>\n

As the name suggests, attic trusses are used to\u00a0create more living space in the attic<\/a>. The bottom beam is used as a floor joist and the supporting beams become the walls of the converted room.<\/p>\n

Scissor truss<\/h3>\n

\"\"<\/p>\n

Scissor trusses<\/a> are often used to create vaulted ceilings. They do not have to be installed on load-bearing beams or walls<\/a>.<\/p>\n

Flat truss<\/h3>\n

\"\"<\/p>\n

Flat roof trusses<\/a> are frequently used to construct flat roofs but are also sometimes used in floor construction. They have a shallow slope to compensate for deflection and allow proper drainage.<\/p>\n

Cathedral truss<\/h3>\n

\"\"<\/p>\n

Cathedral roof trusses<\/a> are ideal for vaulting ceilings in residential or commercial buildings. Their horizontal beam distinguishes them from scissor trusses.<\/p>\n

Double trusses<\/h3>\n

\"\"<\/p>\n

When\u00a0roof trusses are too large to be built and\/or delivered, they can be designed in two pieces, or two half roofs. These wood roof frames<\/a> are known as double trusses and must be assembled on the job site. They are just as sturdy as one-piece standard trusses!<\/p>\n

Mono-pitch roof truss<\/h3>\n

\"\"<\/p>\n

Mono-pitch trusses<\/a> look like right angled triangles. In reality, they are one half of a common truss. Mono-pitch roof trusses are often used to construct sheds, garages or to build a house extension<\/a>.<\/p>\n
