Video: What Is SlenderWall?

The SlenderWall panel’s exterior surface is 2-inches of molecularly bound PVA fiber and welded wire reinforced high-strength architectural precast concrete. The integrated interior frame is made of 14 & 16-gauge, G90 galvanized steel studs spaced vertically at 2-foot centers. The architectural concrete is connected to the steel-stud frame utilizing stainless-steel fasteners, creating a thermal air gap. The frame is filled with factory-applied closed-cell foam insulation. It is the only wall system that combines these time-tested, proven design components to create an integrated exterior wall system weighing about two-thirds less than conventional architectural precast or brick.

What Makes SlenderWall Different

It provides designers with unique and limitless design flexibility and function. SlenderWall provides all of the permanency and flexibility of traditional architectural precast, but benefits from a 2/3’s savings in weight and an integrated interior stud frame. The only truly complete architectural precast concrete building panel on the market.

Exclusive to the SlenderWall system

These additional benefits of the SlenderWall system establish it as the premier exterior wall system of choice for major projects:


  • Superb architectural design flexibility (limitless combinations of architectural precast textures, colors, shapes and finishes)
  • Makes cantilever designs practical
  • Perfect for both re-cladding and new construction


  • Superior durability
  • Permanent components
  • Plant-produced quality
  • Optional plant-installed closed-cell foam insulation and windows


  • Lightweight (30 lbs. per square foot compared to approx. 90 lbs. for heavy architectural precast)
  • Economical (reduces building foundation and structure costs plus shipping and installation costs)
  • Mounts outboard of the floor slab, yielding bonus square footage on each floor
  • Smaller cranes and fewer trailers to jockey

Independently Performance Tested: SlenderWall has been fully tested and meets the required ASTM and AAMA standards.

Technical Design Guide

This Technical Design Guide is presented as a resource for architects, owners, developers, designers and engineers. The intent is to provide information that will aid you in the design-development process of your building project when choosing the SlenderWall system. The ultimate goal is to ensure the profitable execution of your project with a successful blend of quality, beauty and economy. However, since there is so much versatility with SlenderWall, it is not possible to cover every option or detail. Therefore, we will be sending you periodic technical specification updates so please be sure to keep us informed of your current contact information. We also invite you to provide us with your innovative ideas for SlenderWall applications.

NOTE: The SlenderWall building system may not be suitable for use in every possible application and must be installed correctly in order to be installed safely. Only a qualified professional can determine whether SlenderWall is suitable for a particular application or whether a particular installation has been done correctly or safely. Easi-Set Worldwide does not provide these services. Nor does Easi-Set Worldwide license or qualify installers.
