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 a secondary structure, generally composed of metal, concrete or wooden straps, separated between 1.50 and 3 meters. The most suitable profiles for this deck solution are the INCO 44.4 Deck and INCO 70.4 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.
