Aerodynamic functionality is achieved with 11mm strong foam rubber pads. They are readily glued underneath the aluminium bottom rails of the system and are characterised by their high friction coefficients while allowing for a significant reduction of ballast. On top of that, the structural properties of Flat Direct with the air gaps between the modules produce a suction effect in the direction of the roof and achieve the best possible rear ventilation.
Further advantages of foam rubber pads over conventional building protection mats are their good material compatibility with all conventional roofing materials. The migration of plasticisers from the roof membrane, leading to embrittlement, is prevented just as well as mechanical effects on the roofing. Long-term damage is reliably prevented.
Securely anchored to all roof shapes
Flat Direct is usable on a variety of roof types: unilateral or bilateral installation of vertically or horizontally arranged framed modules is possible on gable, pent, shed and butterfly roofs. Secure anchoring is achieved by way of mechanical coupling or counterweights on the roof ridge. A special ridge angle joint was designed for installations on pitched roofs, which can be easily adapted to the local situation. The system solution was designed to meet the specifications of snow load zone 3 and wind load zone 4. Ballast stone holders are available for installations where project-specific parameters require additional ballast.
Proven modular system for quick installation
S:FLEX once again relies on its proven modular system for the new mounting solution: the bottom and module mounting rails are provided as standard products with prefabricated lengths. They are indefinitely extendible with rail connectors. One type of click-in mid and end clamps will suffice to connect modules of all frame sizes.
The Flat Direct, which was developed in cooperation with PMT (Premium Mounting Technologies), is rounded off with optionally available covers for the cable channels integrated into the bottom rails. This way, string cables are protected against permanent and harmful environmental influences, UV radiation in particular. For every project, we also offer an optional system-specific report with a location-based structural analysis.
The new Flat Direct will be presented for the first time at the Intersolar Europe trade fair in hall A3, booth 728. It is available now at S:FLEX in Germany, Great Britain, France, Spain and the Netherlands.
