The deck roof is made up of a corrugated inner support profile, which performs the resistant function of the cover, together with a vapor barrier, rigid insulation and an external waterproofing system. This type of deck roof allows the use of a continuous waterproofing sheet, in addition to eliminating thermal bridges. It is used on flat roofs with slopes from 1% to 5%, and stands out for its adaptability and speed of assembly. Its main function is to provide a watertight closure in constructions that require thermal conditioning of the interior.
The interior steel roof decking will meet the mechanical requirements specified in the project. This interior support profile will be installed on the main structural structure, which is generally composed of metal, concrete or wooden frames, separated between 6 and 10 meters. The main advantage of this system is the elimination of the secondary structure or purlins, since the support profile can reach spans of up to 10 meters between supports, as is the case of the INCO 155.3 Deck profile. By dispensing with the secondary structure, the installation performance of the deck roofi is considerably improved. Furthermore, this support profile serves as both a working platform and a bracing element for the structure. The most suitable profiles for this deck solution are the INCO 100.3 Deck and INCO 155.3 Deck profiles.
In those rooms where it is necessary to improve acoustic comfort, solutions can be used with the micro-perforated interior support trapezoidal profile, to increase the acoustic absorption of the deck roof. These perforations can be made in the webs of the profile in profiles with a large depth, or throughout its surface in profiles with a reduced depth. Typically, drilling of type R5T8 is used for perforations in the webs and type R3T6 for perforations throughout the surface.
