✅ Thanks to its modular vertical extensions, the system adapts to all panel heights from the smallest historical formats to the most recent and future models.

✅ With its universal horizontal extensions, it covers all panel widths, past, present, and future, with no format limitation.

✅ The system is universal and long-lasting: even if panel formats evolve, the S4 Roofit trays will remain fully compatible.

✅ No need to redo everything: only the panels are replaced — the S4 Roofit structure remains intact and reusable.

✅ Both orientations are possible without any extra accessories and without significant additional cost, offering total on-site flexibility.

✅ Waterproofing and finishing are integrated into the system, so no additional parts are required at the top of the roof.

✅ Yes — maximum simplicity that reduces costs, limits installation errors, and optimizes logistics.

✅ The system allows both orientations to be combined, optimizing roof surface and adapting to any configuration.

✅ No battens are needed — direct fixing simplifies and speeds up installation.

✅ Only one horizontal batten is required between two rows of panels to ensure a proper and secure fixing zone.
