In 1993, R&G Matallbau AG was founded and in 2002 the first Sky-Frame system was installed. The company rapidly expanded with a network of distributors and in 2006 was awarded Innovation Prize for Architecture and Technology. Today Sky-Frame is active on nearly every continent and has received many awards and magazine features for the innovative Swiss-made system. Sky-Frame’s indoor-outdoor living solution through frameless sliding doors is the result of the pursuit for supreme product performance.


Excellent performance completes this extraordinary design. The system includes a flush track system as well as concealed head and jambs for a virtually invisible product. A shallow track option is available for areas with height constraints. Sky-Frame is NFRC rated and product testing can be confirmed through the National Fenestration Rating Council directory. Multiple glass options are available for single, dual, and triple glazing. In addition, Sky-Frame is ISO 9001 and ISO 14001 certified.
