MOTO rain screen framing system was designed by architects and installers that were intent on creating a quality, finely detailed framing system that would compliment the high standards set in their architecture and construction.
The patented MOTO system is designed to accommodate all rain screen facades. The MOTO system is designed for interior or exterior applications and will accept many cladding options including: panel systems, wood, metal, and fiber cement siding.
MOTO has been designed to make installation easier and faster to replace an inferior, more commonly used galvanized framing system.
