RENOLIT Tecno Imac

    About us RENOLIT Tecno Imac

    We were the first to produce roofing sheets with a coextrusion system, inventing and patenting the process that allows us to aggregate three layers of different material in a single sheet, with different characteristics specifically designed to increase the technical performance of the material.RENOLIT Tecno Imac was born in 2018 after the acquisition of Tecno Imac s.p.a. by RENOLIT Ondex s.a.s., a French company leader in the production of covering sheets in Bi-oriented PVC, and part of the RENOLIT Group.Driven by a young and dynamic management, it is constantly engaged in a process of innovation and optimization of production which, further developing the patent of Polimglass® (co-extruded thermoplastic material with remarkable performance characteristics), has allowed it to achieve excellent results and to place itself on the national and international market as leader for plastic roofing and coating systems. RENOLIT Tecno Imac s.r.l. is an ISO 9001 certified company since 2001.



    The production technology that makes our sheeting solutions unique

    Co-extrusion is a manufacturing process based on the transformation of a plastic substrate layer, involving the simultaneous processing of different components so that they emerge from the production machine in the form of layered bonded sheets that combine the best features of the constituent composing materials.

    The Tecno Imac production stations are organised in units of three extrusion machines. In each extrusion machine, the composing mixture components (resins, plasticisers, stabilisers, pigments etc.) are fed through hoppers into a cylindrical chamber. Here the mixture is heated and compressed with worm screws s until it reaches the co-extrusion flat head where the layers, created by the individual extruders, converge to form a coarse sheet. This is then laminated in a calendering press and it is shaped into the final profile.


    The classic elegance of the proportions of the different types of traditional roofing, the vivid and natural colors and the goffered and antiqued finishes make our sheets systems aesthetically unbeatable.


    In spite of their resistance, our coverings are very light, from 4 to 6 kg per square meter. Easy to handle and easy to install.


    The simplicity of the overlapping system and the accessories for fixing and refinishing allow the realization of beautiful and resistant coverings in a very short time.

    UV resistance

    The particular constitution of the layers of polymers in our co-extruded products is such as to ensure a very high resistance to fading. In fact, our sheets are guaranteed!

    Strength and mechanical resistance

    The constant updating of the chemical formulations that we use has allowed us to create increasingly thinner roofing sheets with remarkable mechanical characteristics.

    Chemical resistance

    A RENOLIT Tecno Imac co-extruded roofing sheet is the ideal roofing sheet in all environments characterized by high chemical aggressiveness, such as coastal areas, livestock buildings or in some kinds of industrial plants.
