About the Product

How KORAX® Rainscreen Panel functions and benefits your project

KORAX® RAINSCREEN PANEL is the most effective method of managing moisture in exterior wall assemblies because of the incorporation of a rain screen.  The rainscreen prevents water from entering the wall assembly from the exterior or reaching the cavity from the interior.  Water is diverted out through weep holes or dried out by the circulating air through venting.

KORAX® RAINSCREEN PANEL is made of expanded polystyrene board with vertical and horizontal grooves in the back that create a cavity. The panel is easily attached by mechanical fasteners over the system’s insulation layer.  The vertical channels in the panel create cavities 10mm deep and 60mm wide that lead water to flashing and weep holes at the bottom and vent holes at the top of the wall section also allowing air circulation.  The vertical ribs are interrupted by horizontal channels, creating nodes which slope back towards the panel, providing positive drainage away from the wall.

KORAX® RAINSCREEN PANEL is suitable for:

  • Walls with EIFS
  • Wood or steel stud walls with stucco finish
  • Rubble masonry finish
  • Wood or steel stud walls with metal or vinyl siding
  • Basement walls


  • The most effective way to manage moisture in exterior wall assemblies
  • Easy installation with mechanical fasteners over the systems insulation layer
  • Low-cost rainscreen solution

Energy Efficiency

Thermal bridging caused by conventionally installed steel shelf angles profoundly affects the energy efficiency of your wall system, limiting the effectiveness of insulation by over 50%. Standing off the shelf angle allows for continuous insulation behind the shelf angle, reducing thermal bridging by only 14%.

Easy Installation

FAST™ Thermal Brackets are readily available in any size height or depth to accommodate any shelf angle, anchoring system, and backup wall type. Installation is quick and simple—anchor the FAST™ Thermal Bracket into the backup wall and slip the angle in. In most cases, only one trade is needed onsite for the complete installation.

Onsite Adjustability

FAST™ Thermal Brackets offer significantly greater onsite adjustability than conventional angles. Slots on the bracket offer 1- ¾″ of vertical adjustability, and the FAST™ Thermal Bracket can be rotated to ensure the shelf angle is level. Horizontal adjustment is provided by FERO Shim Plates placed behind the bracket.

Reduce Cost

The depth of the FAST™ Thermal Bracket can be increased to accommodate any wall cavity size while continuing to use a standard 4×4×1/4” shelf angle. This eliminates the need to use larger, much more expensive shelf angles in walls with thicker insulation and larger cavity sizes.

The adjustability and ease of installation by a single trade also reduce cost by speeding up installation time and reducing labor costs.

FERO’s experienced technical staff is available to assist in designing a FAST™ Bracket solution to minimize project materials costs.
