What is the rafters?

The Truss rafters, also known as a truss rafter, are engineering triangulated support structure of the roof, which is usually built outside the locality and then supplied to the site of construction. Such a structure may consist of metal or wood, but is most often made of lumber dried oven composed with steel nail plates. The function of the lattice is to support the full weight of the building roof and transfer this load to the outer walls. These components differ from roof rafters, which are individual rays, in several ways. Each truss beam is created for precise specifications using information provided by the home builder. The dimensions of the house are used for mathematical determination of the number of trusses and the range of loads needed to carry the load, which includes roofing materials. Most roof lamps are now pre-fabricujed and a factory that allows a more accurate product than the construction of roof beams in the field.

There are several advantages of using the rafters on conventional ceiling beams and roof supports. Cost savings are achieved by reducing the wood used and making in a factory that saves labor costs. Preschool units are assembled inside, where materials such as wood are not exposed to elements that can cause deformation. Current and other unconventional roof designs can be easily adapted without significantly increasing the cost of construction. These systems can also bridge larger areas than conventional rafters, allowing buildings with a smaller number of inner walls carrying weight and resulting in a more open design.

One of the disadvantages of using the rafters, at least from the point of view of the house owner, is that their design and construction leave less attic for storage or extension. This problem can be solved using attic truss beams. These lattice systems are designed specifically to allowy additional square shots depending on the design of the house, with approximately 8 feet (2.4 m) height. Another plus is that the lower chords of the attic are specially designed to allow additional weight, which makes them very robust. Other costs of the attic are minimal, usually just a few dollars per square feet.

Two most commonly used types of roof trips are Pitched or common design and parallel chord, also known as a flat truss. The common ride is the best known and most respected in most house construction projects. Identifiable in its triangular form, it is the most common type of rafters used in the construction of the roof. Parallel truss beams are mostly used in the construction of the floor and is named for its parallel chords over the upper and bottom.

Many variations of truss rafts are available, depending on the type and style of home position. For example, scissors are commonly used in households with cathedral ceilings and increasedThe lattice beam is often a choice for energy -efficient construction, as its shape allows further insulation of the attic and tight moisture and barrier of steam. It is essential that the house builder knows exactly what style of the framing system of roof trusses wants before ordering these components. The measurement and specifications should be as accurate as possible and it is recommended that each roof lattice is thoroughly checked when delivery in the workplace to ensure the quality and satisfaction of customers.
