Nowadays, the construction industry most often uses prefabricated elements – it applies either to concrete, hollow blocks or roofs. These days, it would be very difficult to imagine that the particular components are manufactured at the construction site. The technological progress and the computerisation of production processes have resulted in the fact that the above-mentioned elements are now manufactured in specialised plants from where they are later delivered to the construction site at the most convenient time.

It is worth knowing that the prefabrication of rafter framing is a technology, which is highly popular in the well-developed countries such as France or Sweden (about 90% of roof structures are made in that way). Prefabricated roof structures made from solid timber joined with the help of nail connector plates by Mitek are also widely used in the Czech Republic, United States or Canada.

The prefabrication technology of trusses joined by nail plates produced by the company Mitek is the best solution for the construction of residential superstructures. Prefabricated trusses are light and they only slightly weigh down the roof and the foundations of the existing building. The bottom chord of the truss may independently transfer the load to the outer walls. In addition, the fact that the truss construction can be shaped in various ways helps to adjust the body of the superstructure into the surroundings of the building.


Advantages of prefabrication:

  • quick assembly of components that are produced in an outside plant – in good weather the assembly of the rafter framing, roof covering and implementation of anti-flood protection takes only two days (it is extremely important in case of inhabited buildings),
  • limitation to a minimum of technological discontinuation of works (thanks to the continuity of production),
  • efficient use of materials,
  • comprehensive finishing,
  • possibility of arranging the residential space in various ways (thanks to the implementation of structures without pillars in the attic),
  • shortening of working hours at the construction site,
  • shortening of the production cycle,
  • lightness of the structure,
  • limitation of construction works exclusively to assembly works,
  • energy efficiency (thanks to remarkable technical parameters),
  • possibility to manufacture the prefabricated elements independently from the weather conditions,
  • high quality of constructed structures,
  • lower construction costs,
  • accuracy of construction,
  • possibility of constructing roof structures in almost every possible shape
