Sto Corp. Introduces StoEnergy Guard(TM)

Advanced Cavity Wall System Features Waterproof Air Barrier, Proven Drainage Technology and Continuous Insulation to Provide Energy-Efficiency and Durability with Almost Any Cladding Type

ATLANTA - To address new building code requirements, Sto Corp., the innovative world leader in cladding, coating, and restoration systems, introduces StoEnergy Guard(TM), an integrated cavity wall solution that is used for protection under multiple cladding types, including stone, siding, stucco and more. With StoEnergy Guard, the company leverages cavity wall design and rainscreen technology to provide energy efficiency and durability in a simple yet effective solution. StoEnergy Guard integrates a fluid applied waterproof air barrier, sheathing joint and rough opening protection, proven drainage technology, and approved continuous insulation - into a flexible system that can be designed to meet individual climate zone and building code requirements.

Today's buildings have to be all things at once - energy efficient, durable and sustainable. StoEnergy Guard has engineered the highest performing products into a flexible solution: one warranty and proven components that are designed to work together seamlessly under multiple cladding types. Easy to install, StoEnergy Guard offers a choice of compatible components for specific design and climate needs. Not only does it work under most cladding types, but also in buildings that combine more than one cladding, such as stone and stucco.

For increased safety and comfort, StoEnergy Guard reduces energy use in hot and cold climates and is comprised of Class A building materials tested for low flame spread and smoke development. Designed to protect the entire building, it offers improved air quality and thermal comfort as well as resistance to mold and mildew. Its StoGuard® component provides a continuous, fluid-applied air barrier membrane that bonds directly to sheathing to resist air and water penetration as well as a waterproof moisture barrier that protects against the damaging effects of incidental water damage. The Sto DrainScreen(TM) mat facilitates moisture escape between the protected substrate and cladding by allowing water that reaches the back of the cladding to drain to the outside, and it also helps speed the drying of moisture-ladden air. And, incorporating approved continuous insulation enhances energy efficiency and eliminates thermal bridging while significantly improving the effective R-value of the wall assembly. StoEnergy Guard uses proven components and is compliant with numerous codes and standards including the International Building Code (IBC) 2012, IECC 2012, IGCC 2012, NBC 2010, ASHRAE 90.1 and ASHRAE 189.1 as well as state and local codes.

Sto provides the latest in energy-efficient wall technology and Sto products are safe and nontoxic, and have low VOCs. As a leader in environmental responsibility, Sto continues to incorporate sustainable practices throughout its operations and helps reduce the environmental impact of a building by saving energy and using materials with recycled content.
