The simple modularity of our system means that starting from the main module we can expand the construction in every direction. The extension modules are natural extensions that allow endless combinations and even large projects. The freestanding model has four columns, each containing rainwater drainage pipes, while the leaning versions both with blades parallel to the fixing wall and perpendicular allow an effective extension of living spaces to the outside and are equipped with wall fixing brackets and two columns on the front side. Parallel leaning extensions, perpendicular leaning extensions, corner extensions... many combinations to customise the own covering system and meet countless construction requirements. Flexibility is therefore the distinctive per excellence element of the entire structural project, to which in addition the unique SKY 2 roofing module allows you to enjoy the advantages of a bioclimatic roof thanks to its perfect integration possibility into existing load bearing elements.
