Sto, the leader in wall cladding systems and the world’s largest manufacturer of insulated wall systems, now offers the most advanced technology in prefabricated insulated wall panel solutions. Our systematized approach to panelized construction offers many benefits over traditional precast panels. Sto Panels are lightweight, energy efficient, durable and require only a fraction of the typical installation time. 

Why Panelize?

  • Manufacturing, Not Construction - Prefabricated exterior wall - panels offer several advantages over traditional "stick-built" framing.  These panels are built in a controlled manufacturing environment versus unpredictable field conditions.  This not only guarantees a higher degree of quality, but also prevents unexpected schedule delays due to weather considerations and other factors.
  • Superior Quality - Manufactured to match drawings and specifications exactly.
  • Design Considerations - There are a variety of exterior cladding options to meet any design.
  • Weight Reductions - Prefabricated wall panels can weigh up to 90% less than a precast panel of the same size.  
  • Reduce Manpower - The amount of manpower required to install wall panels is significantly less than in traditional framing.  As opposed to having multiple trades in the same space for framing, waterproofing, finishing, etc., only a small installation crew is required.
  • Reduce Scaffold - Minimizing the use of scaffolding reduces significant cost, time, and safety risk throughout the construction process.  Panelization is also beneficial on projects with zero lot lines and limited staging areas, such as downtown high rises.
  • Improve Safety - Manufacturing is 15 times safer than traditional construction.  Building panels in a horizontal, ground level environment and installing them from a crane greatly reduces the risk involved in building off scaffolds.
  • Lean Construction - Reduce waste with lean construction methods that eliminate scrap metal, sheathing, and insulation disposal onsite. 
  • QA/QC - The manufacturing process allows for 100% of the building envelope to be inspected and all punchlist items to be pre-punched prior to panel installation.  Critical waterproofing details are highly repeatable and easily inspected.
  • Positive Schedule Impact - Panelization allows for the building's exterior skin to be under construction, in some cases ready to install while the structure of the building is still being erected.  As a result of the accelerated duration for the exterior wall installation, the building is dried in at an earlier stage.  This has a positive schedule impact that benefits multiple trades.
  • True Performance Mock-Ups - Review actual design of a panel with a complete off site mock-up. Ensure all systems functions are designed as intended. 
  • Waterproofing Details - Easily inspect critical waterproofing details in a repeatable, standardized manufacturing process. 
  • 5 Year Industry Leading Warranty - Performance warranty for 5 years. 



Reduce your building envelope installation time by up to eighty percent when compared to conventional field-installed construction methods.


Take advantage of continuous insulation panel walls that can have up to ninety percent less weight than other panel and conventional wall types.


Easy installation means less labor. Reductions can be as much as going from 60 workers to 6 when compared to typical on-site construction methods.
