Single-Skin Modular Panel System
SurFlex is a modular, single-skin pressure equalized rainscreen panel system which has been tested to AAMA 508. It has interlocking joints that assist in showcasing a very modern and contemporary look to exterior facades.  Using an automated production process, this system allows natural sheet metals to be quickly manufactured into panels within seconds.  SurFlex also installs quite easily as it is fastened directly to the building substrate.  Therefore it does not require any extrusions or clips.   This process makes it one of the most economical and cost-effective panel systems on the market. For either a subtle or dramatic effect, SurFlex has numerous design and pattern possibilities. They include Standard, Perforated, 3-Dimensional or Tapered aesthetic options, as shown below.

SurFlex is a dry joint system designed, engineered and manufactured by Sobotec. Modular panels create a pressured equalized rainscreen system that does not require clips or extrusions. SurFlex eliminates exposed rivets and fasteners at the panel perimeter, providing a crisp, clean appearance. SurFlex has been proven and tested to the following specified performance requirements:

  • ASTM E1233
  • Cyclic Static Air Pressure
  • ASTM E330
  • Structural Performance ASTM E28
  • Air Infiltration ASTM E331
  • Water Penetration AAMA 508
  • Pressure-Equalized Rainscreen System

Sobotec’s SurFlex panel system is adaptable to different project conditions. Our system design allows for modifications without sacrificing performance. The system integrates with flashings, closures and trims manufactured by Sobotec. Selecting a single source provider like Sobotec allows for efficient integration of these key building elements creating a rain screen system which meets the highest design and performance requirements.

All SurFlex panel systems are made in North America, using recycled material. Applicable for LEED credits, SurFlex provides a high degree of sustainability as the panel system can be reused or recycled at the end of the products lifecycle. Manufactured using a lean process, SurFlex can assist projects to achieve zero-waste when the designs are optimized.  This allows projects to reduce their overall environmental impact and carbon footprint.
