Knight HCI System Rainscreen Attachment

Horizontal-Girt Continuous Insulation Attachment Should Be Simple to Design + Easy to Install

KNIGHT’S AWARD-WINNING HCI™ SYSTEM PROVIDES OUTSTANDING THERMAL PERFORMANCE BY WAY OF TRUE CI (CONTINUOUS INSULATION). AS A COMPLIMENT TO THE ORIGINAL CI® SYSTEM, THE HCI SYSTEM ENABLES VERTICAL CLADDING (AND SECONDARY RAILS) TO BE INSTALLED DIRECTLY TO THE HCI-GIRT™. THIS OFFERS EASY INSTALLATION, BROAD DESIGN FLEXIBILITY, AND COST SAVINGS, ALL WHILE STILL EASILY MEETING NORTH AMERICAN ENERGY CODE REQUIREMENTS.

THE HCI SYSTEM USES UNIQUE ¾” DEEP HORIZONTAL GIRTS- CALLED HCI-GIRTS –DESIGNED TO PROPERLY DISBURSE THE FAÇADE LOADS OVER EXTERIOR RIGID BOARD INSULATION – WITH ONLY UNIQUE THERMALLY ISOLATED FASTENERS PENETRATING THE THERMAL BARRIER THUS MINIMIZING THERMAL BRIDGING. FOR BASIC, COST-EFFECTIVE VERTICAL CLADDINGS, ONLY A SINGLE LAYER OF HCI-GIRTS MAY BE NEEDED. FOR MORE COMPLEX CLADDING DESIGNS OR TYPES, CHOOSE FROM A WIDE VARIETY OF KNIGHT WALL SECONDARY RAILS FOR THOSE PANELS REQUIRING SPECIFIC ATTACHMENT POINTS.

HCI SYSTEMS COMPONENTS ARE PRODUCED IN STANDARD AND CUSTOM LENGTHS, IN EITHER 16 OR 18 GAUGE ZN-AL-MG COATED STEEL (STANDARD SILVER OR BLACK PVDF COATED) AND ALSO AVAILABLE IN STAINLESS STEEL.

THE HCI SYSTEM ATTACHMENT COMPLETES THE RAINSCREEN ENVELOPE DESIGN, WHETHER CHOOSING METAL PANELS, ALUMINUM COMPOSITE MATERIAL (ACM) PANELS, FIBER CEMENT, GFRC, OR MANY MORE. AND CHOOSE ANY BRAND OF INSULATION THAT MEETS MINIMUM COMPRESSIVE STRENGTH AND CODE REQUIREMENTS, SIMPLIFYING DESIGN SPECIFICATIONS.

 

ADVANTAGES TO THE KNIGHT HCI™ SYSTEM RAINSCREEN:

  • Horizontal HCI-Girt™ can be spaced up to 36 inches O.C.*
  • Support cladding weighing up to 9 PSF*, covering many popular cladding types
  • Real labor savings – no notching or cutting of exterior rigid board insulation like with Z-girts, brackets or clips
  • Thermally isolated wall anchors with specially designed ThermaStop™ washers come preassembled
  • Highly corrosive-resistant Zn-Al-Mg ZM40 (ASTM A1046) coated steel provides a long service life vs. typical G90 Galvanized steel
  • Black PVDF finish or stainless steel options available, competitively priced
  • Easily installed over any type of substrate – steel studs, wood studs, CMU, concrete, even brick
  • Engineering calculations provide design load compliance for each specific project
  • Attach nearly any type of cladding – supplied by any manufacturer – with easy and efficient detailing and installation
  • Use any manufacturers insulation meeting minimum compressive strength and other code requirements
  • Cladding can be attached directly to the horizontal HCI-Girt or used with optional vertical rails (such as PanelRail™ or RevealRail™)
  • Excellent ventilation with a 3/4-inch minimum continuous rainscreen cavity
  • Pre-engineered and 3rd party tested for proven performance and durability
  • Competitive, budget conscious assembly that meets ASHRAE 90.1 standard
  • Complete, drop-in rainscreen attachment system – girts, thermally isolated fasteners, rails and engineering – one source liability for the whole system
  • Limited labor and material warranty

 

 

*Maximum allowable spacing & dead load (weight of cladding) is based on total load (dead + live) acting on the assembly. Wall anchors should be specified & supplied by Knight for written limited warranty. Knight will specify the exact anchor type, embedment depth and spacing for anchors in project specific engineering packages (required for written limited warranty). ThermaStop thermal isolation washers must always be used with the HCI or CI-System, no matter what wall anchor is used. Contact KWS for more information.
