Integrated Enclosure System (IES)

The IES system uses a tube steel frame that allows for larger openings and connection points that can span from column to column.  The exterior precast concrete cladding and integrated frame system is isolated from the structural stresses associated with wind loading (tested to 226 mph), steel frame movement, and expansion and contraction.

The lightweight wall system is Energy Code compliant, NFPA 285 fire-rated, and contain factory-installed, closed-cell foam continuous insulation, which have been tested to meet thermal requirements from Zone 1 through 8The exterior precast face acts as the weather barrier, air barrier and vapor barrier, so other finishes can be applied to the face of the precast without compromising the integrity of the building envelope.

In addition to all of the advantages the new lightweight panel systems provide, the precast concrete still retains the ability to provide an endless variety of shapes and sizes, colors and finishes. As with all of Wells’ panels, the aesthetic versatility is truly only limited by your imagination, and can take virtually any form a designer might want.

Architectural Precast Finishes
  • PCI Quality Control Standards
  • Same colors, textures, and finishes as traditional precast
  • Welded-Wire Mesh and Fiber Mesh Reinforcement
  • Returned finishes at edges, openings, and ends of panels
  • Other finishes (metal panels, laminates, etc.) can be cast-in or preinstalled prior to shipping
  • Multiple finish offerings reduces the need for other trade contractors on site.
Steel Frame Back-up
  • HSS Framing
  • Optional preinstalled electrical boxes and conduits
  • Hat channel / Steel “Stud Pack” ready
Factory Installed Spray Foam
  • Installed in factory controlled conditions
  • Energy Code Compliant
  • UL and NFPA 285 tested
  • Continuous Insulation for applicable Climate Zones
  • Insulation R-Value of 7.4 per inch
  • Provides primary vapor barrier for exterior wall
  • Improved consistency and Quality Control
  • Fewer on-site trade contractors
  • Panels are already insulated when they arrive on site
  • Spray foam meets 2020 guidelines for blowing agent restrictions
Factory Installed Windows
  • Installed and caulked in factory controlled conditions
  • Greater control over quality of install
  • Installation performed at ground level in controlled conditions
  • Window testing performed in factory prior to arriving on site
  • Factory installed windows allow for faster enclosure schedules
  • Fewer on-site trade contractors
  • Eliminates the need for material staging areas on site
  • Panel openings shipped to the site weather tight allowing other trades to start sooner & eliminates temp enclosures
  • Lower overall cost
Testing – Research & Development

Wells continues to invest time and resources in Research and Development to proactively assure our products meet and exceed the required testing standards necessary for today’s construction industry.

Final NFPA 285 testing reports have been completed and Wells’ SlenderWall and IES systems now have their own assembly listing in the UL catalog for Exterior Wall Systems: EWS 0051.  This is a test of a two story section of our light weight wall panels to verify that our system does not contribute to any vertical flame spread on the exterior of the building. The testing reports will be done on our actual systems so that judgment letters will not be needed.
