Inalfa Roof System's second-generation, bottom-load, integral multipanel roof systems can be inner or outer sliding systems and offer the same amount of exterior light into the vehicle as all-glass panel systems. Other features include improved functionality, a larger opening, and reduced weight. The company's bottom-loaded systems allow vehicle manufacturers to retain all structural elements within the vehicle's architecture. To reduce its environmental footprint, Inalfa's latest-generation roof systems reduce typical sunroof weight by more than 20%, decreasing the overall vehicle mass and improving fuel economy. Products feature recycled materials where possible in the manufacture of new parts, and the company is integrating solar cells into its roof systems to create electric, hybrid, and conventional vehicles that are more energy neutral.
