Hurricane Impact Systems

Protection for Coastal Construction.

Sto Hurricane Impact (HI) Systems provide a full range of exterior cladding options to protect against hurricane and tropical storm winds, water intrusion, and wind-borne debris which is a leading cause of building envelope failure. All of Sto’s Hurricane Systems meet the stringent Miami-Dade County, Florida NOA criteria for impact resistance, air and water infiltration, and wind load resistance.

All Hurricane Systems can be installed economically on a variety of construction types, including: metal frame with gypsum sheathing, wood or steel frame with plywood sheathing, or concrete masonry. Sto also provides a wide variety of decorative and protective wall finishes, affording outstanding appearance and superior wall protection against some of the most severe weather conditions in North America.

Other key features of the Hurricane Systems include:

  • Competitively priced with other cladding systems.
  • Fire-resistance for up to two hours.
  • Lightweight and easy to install.
  • Backed by Sto’s Limited Labor and Materials Warranty.
