Knight MFI™ S-Series System Rain Screen Attachment

CAD Drawings BIM Models Knight Wall Systems Knight MFI™ S-Series System Rain Screen Attachment

The Knight MFI™ System dramatically reduces the thermal bridging within rain screen systems using mineral fiber insulation, while providing limitless design options for building facades; combining energy efficiency, façade versatility, and long term sustainability.

The MFI System uses unique thermally isolated intermittent clips – called Thermabrackets™ – that can be spaced all the way up to 32” O.C. They use a unique thermal isolation assembly, called ThermaStop™, creating one of the most thermally efficient mineral fiber cladding attachment systems on the market today – typically outperforming standard metal clips and rails and even FRP brackets and rails.

The continuous rails attaching to the brackets may be oriented vertically or horizontally for maximum design versatility and quick installation. Quickly plumb facades during install with an adjustable rail/bracket connection or use KWS unique, self-aligning, structural shims. The MFI System can be used with or without secondary rails for fiber cement, metal panels, terra cotta, phenolic panels or Aluminum Composite Material (ACM) and many more.


  • S-Rail may be attached to ThermaBracket-S in a vertical or horizontal orientation

  • Drained/ventilated cavity created by vented S-Rail and uninterrupted by obstructions: 3/4?

  • Additional layer of rails may be attached to the S-Rail for freedom of layout independent of stud layout or expanded panel compatibility (see typical details and specifications)

  • S: Static – the S-Rail to ThermaBracket connection is fixed with about 1/8? built-in adjustability

  • Adjustments made on an out-of-plumb or out-of-plane substrates are made by Knight’s supplied isolator shim without sacrificing thermal performance

  • Isolator shim fits square, straight and flat to the back of the ThermaStop system by means of raised lips that securely lock the shim in-place for maximum structural integrity

  • Knight’s isolator shim is included with every S-Series MFI System shipped
