Frequently Asked Questions

Q: What’s included in a prefabricated finished exterior StoPanel wall?
Everything. StoPanel® prefabricated exterior walls consist of cold formed metal framing and all other components in a specified wall assembly, including sheathing, air and moisture barrier, continuous insulation (ci), sub-framing (if applicable), and facade aesthetic.

Q: Where are Sto Panels fabricated?
At local StoPanel Affiliate manufacturing facilities. Click Here to reach out to a Sto Panel Technology specialist to find an affiliate near you.

Q: How are the panels installed in the field?
With the use of on-site cranes.

Q: How are panels attached to the building?
Every panel is custom engineered, including connections, for its unique configuration, position, and the structural frame to which it must attach. Typically the panels are held about 1″ off the edge of the slab and are connected at every stud with custom designed steel plates, angles, or other prefabricated connectors as required to carry the design loads and to handle expected movement of the building frame.

Q: What Claddings can be applied over Sto Panels?
Various claddings such as: Continuous Insulation (ci) Systems, Brick, Metal and others. See all of the StoPanel systems here.

Q: Are there size limitations for various Sto Panels?
Yes, approximately 300 sf. per panel based upon specific project requirements.

Q: How is fire-stopping handled in panel wall design?
Based on ESR -1233, floor-line fire-stopping should be, as a minimum, 4 pcf. mineral wool insulation in each stud cavity and at each floor line, attached with z-clips or equivalent fasteners. The fire-stopping detail selected by the design professional should have a tested hourly rating to match that of the floor/ceiling assembly.

Q: How are the panel-to-panel joints addressed in the field?
A dual stage sealant joint is required and the sealant is typically installed in the field working off a swing stage.

Q: Does Sto Panel offer a drainage panel?
Yes, most StoPanel assemblies offer drainage as a standard component.

Q: Can Sto Panel be utilized in high velocity hurricane zones such as Miami-Dade County?
Yes, with using StoPanel Impact ci that meets both Large and Small Missile Impact Resistance requirements. See our StoPanel Impact ci system here for more information.
