Sto Insulated Concrete Form (ICF) Finish Systems

Insulating Concrete Form (ICF) is a system of formwork for concrete that stays in place as permanent building insulation for energy-efficient, cast-in-place, reinforced concrete walls, floors, and roofs.

The forms are interlocking modular units, somewhat like Lego bricks, that are dry-stacked and filled with concrete, serving to create a form for the structural walls or floors of a building. ICF construction is becoming increasingly commonplace for both low rise commercial and residential construction as more stringent energy efficiency and natural disaster resistant building codes are adopted.

StoTherm® Hurricane Impact Systems

Protection for Coastal Construction.

Every year, Hurricanes threaten the coastlines of North America, striking coastal areas in 82 of the last 100 years. From Hurricane Dennis to Katrina, Rita to Wilma, the new millennium has brought 27 major Hurricanes and along with it more than $56.8 billion in property insurance losses for homes and businesses.

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.
