Flat roofs, where no roof penetration is possible or desired, but where roof construction and load capacities do not allow for significant ballast, require alternative aerodynamic systems and a largely ballast-free solution. Enabling optimized module orientation can also be a problem.


Aerodynamically designed frames represent a sophisticated, trend-setting concept with fast installation. They can be removed without a trace, and are as stable, storm-proof and durable as ballasted or assembly systems firmly connected to the roof membrane. The LEICHTmount systems can be installed equally well facing south or east/west, providing an uncomplicated flat roof installation method. The new systems are structurally optimized and use less material with an aerodynamic design and pre-assembled aluminum coated safety membrane. The results are claimed to equal lower cost for materials and shipping, quick and easy assembly, less ballasting without penetration and a choice of orientation.

Both new ‘LEICHTmount’ systems  have been wind-tunnel tested for up to 150 mph, conform to the UL 2703 certification, provide effective water drainage and module ventilation, and are suitable for roof edge zones. The systems are preassembled and S:FLEX, Inc. provides a complimentary ballast calculation with roof layout and optional wet stamp when requested and have a long product life with a 25 years limited product warranty.


July 2015 onwards.
