Sigma Vci.40 Stainless Steel Cladding Support System

Sigma Vci.40 System

Panel sub-framing system with stainless steel Sigma wall brackets for panel attachment with concealed, undercut anchors for cement composite, ceramic, stone, HPL, and fiber concrete panels. The back of each panel is pre-drilled using an undercut drill bit to receive the hanger clip and expanding bolt anchor.

ECO Cladding’s Sigma U stainless steel brackets have low thermal conductivity and an isolator pad to reduce heat loss and significantly decrease thermal bridging.

Engineered to address dead load, wind load, seismic concerns, thermal requirements, and material deflection for either steel stud or concrete backup conditions. 

Key Sigma Vci.40 System Features:

  • Self-adjusting: Up to 1.5” of internal adjustability. Level and plumb not a problem. Cavity depths from 2” to 12”. Helping hand acts like another laborer on your team.

  • Universal Bracket: Both vertical and horizontal orientation can be achieved using one bracket. Stiffening ribs create optimal engineering design.

  • Thermally-broken: Pre-installed isolator pad provides material separation and thermal break. Made of enhanced thermal resistant material. Achieve U-values to meet ASHRAE 90.1. Passive House certified component.

  • Non-combustible: Fire resistance to address fire codes.

  • High-grade Stainless Steel: Grade 304 stainless steel is pre-punched and accommodates heavy rainscreen panels and high wind loads.

  • Recycled Content: Excellent recycled content profile with 18.29% pre-consumer and 63.77 post-consumer.

  • Engineered System: Fixed and Sliding Points allow for expansion and contraction of the subframe system. One to three anchor design create numerous economically efficient engineering solutions. 

  • Made in USA: USA-made steel. Buy America / Buy American Advantage.

Bracket Design Benefits

Fixed and Sliding Points

The wall bracket fixed point carries the dead loads and windloads to the load-bearing wall. The connection between the wall bracket and profile is fastened immovable in the “round hole”.  The connection between the wall bracket sliding point and the profile is designed for thermal linear expansion and contraction. For a sliding point, only wind pressure loads are carried to the load-bearing wall.

Thumb Hold Feature - Built In Adjustability 

Two advantages in one!  Our wall brackets give installers an “extra hand” while they get the wall level and plumb and the “thumb-hold” feature of our brackets allows the system to have a +/- 3/4” adjustment without the need for external shims. The thumb hold design feature creates huge labor savings.

Bracket Sizes

Shallow or deep, ECO wall brackets can accommodate your building’s cavity depth.  Sigma U brackets are available in 11 sizes to accommodate 2.50" - 13.75".  Alpha V brackets are available in 12 sizes to accommodate depths of 1.38” to 10.04”.  Alpha H brackets are available in 8 sizes to accommodate depths of 1.38” to 9.25”. 

Engineered System

ECO Cladding is committed to providing a fully engineered system (both C.I. Subframing and Panel Subframing) in which the entire wall is engineered to accommodate project wind loads, seismic loads, building slab-to-slab deflections, and thermal movements of materials.

Cost Effective

Fewer Holes in Air Vapor Barrier

ECO Cladding wall brackets maximize the distance between attachment points on the walls, creating fewer penetrations through the continuous insulation (c.i.) plane and into the weather-protective membrane, thereby reducing air and water leakage opportunities. In addition, our wall brackets are detailed to create a seal between the bracket and membrane. 

The Cost-Effective SubFraming!

ECO wall brackets are easy to install and are more cost-effective in labor man-hours, allowing materials to be rapidly set even when backup walls are not plumb or true. Since our wall brackets have better-spanning distances than competitors, labor time can be cut in half.
