The multi-layer curved cover is formed by an external non-self-supporting curved profile, which acts as a sealing element, and by an internal support non-self-supporting curved profile that performs the resistant function. Both profiles are fixed to each other using a separator profile, which maintains the necessary distance to accommodate the insulation. The main function of this solution is to provide a watertight seal on the curved roofs of buildings that require thermal conditioning inside.
The curved profile of the exterior cladding will meet the mechanical requirements specified in the project and will also guarantee the watertightness of the roof. The curved interior support profile 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 profiles are more suitable for this curved roofing solution: INCO 30.5 Curved, INCO 44.4 Curvedand INCO 70.4 Curved profiles.
In those rooms where it is required to improve acoustic comfort, solutions with the curved micro-perforated interior support profile can be used to increase the acoustic absorption of the cover. 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.
The curvatura of the trapezoidal profile is recorded through a series of equidistant contours which, with a few folds, provide the necessary curvatura.
