Pianaliant is the roofing designed to combine the winning features of Aliant with the needs of flat ceilings. The modules, monolithic and prefinished like Aliant but with a perfectly flat intrados, allow both the easy execution of internal divisions and the creation of any planimetric shape. Pianaliant tiles can be mounted side by side or spaced out with continuous zenithal skylights (centre distance 270÷290 cm), as well as spaced out on request with the insertion of secondary intercalary elements of the Aliant Spazio/Shed system. The criteria of structural perfection and finishing accuracy, as well as flexibility, versatility and competitiveness, are the reasons that have made Pianaliant the protagonist of a central role in the market of flat intrados covered surfaces.
