With the PREFA aluminium diamond roof in the format 44 × 44 cm, PREFA is once again providing a strong, innovative creative impulse. The enlarged surface structure allows the free interplay of traditional form and modern accents without sacrificing maximum durability and extreme weather resistance. The innovative PREFA design rhomboid roof impresses with its minimal weight as well as maximum efficiency in handling: the integrated fastening strips enable quick and cost-effective installation of the roof and façade elements.
