ci Systems

The world-class building-science experts at Sto continue to lead the way in advancing energy efficiency, durability and aesthetic appeal. Today’s energy codes and regulations reflect many of the design principles embodied in our Continuous Insulation (ci) Systems, and the proven performance of Sto’s next-generation EIFS appeals to designers, contractors and owners alike.

StoTherm® ci Wall Systems (EIFS)

Integrated Wall Systems that deliver the best in performance, sustainability and design flexibility.

Sto’s next-generation StoTherm® ci systems integrate the following key elements: continuous insulation (ci), an air/moisture  barrier, drainage and a variety of textured finish options to create a superior, sustainable wall cladding. This high-performing, eye-catching system saves energy and stays attractive for years. StoTherm® ci improves indoor comfort and air quality while maintaining maximum curb appeal and lowering overall life-cycle costs. 

System Features

• Waterproof Air Barrier
  Protects the wall from moisture intrusion minimizing risk of water damage and associated repair costs.
• High R-Value
  Continuous insulation with high R-values provides significant energy cost savings by eliminating thermal bridging.
• Code Approved
  Complies with both ICC and IECC code requirements for continuous insulation.
• Outbound Dew Point
  Prevents condensation and freeze damage by placing the dew point outside the stud wall cavity.
• Reduced Structural Loads
  StoTherm® claddings are very lightweight, resulting in reduced structural cost requirements.
• No Mechanical Fasteners
  No penetrating nails or screws to attach the insulation means no thermal bridging.
• Low Maintenance Cost
  Coatings and finishes with advanced acrylic and Lotus-Effect technologies resist dirt pickup, peeling and cracking.
• Lowest Life-Cycle Cost
  StoTherm® ci claddings have the lowest life cycle costs compared to non-insulated brick and stucco claddings.
• Premium Finishes & Coatings
  Sto high performance finishes and coatings provide superior weatherability and resistance to UV fading, mold and mildew.

StoTherm® ci

Superior energy savings, design freedom and versatility.

StoTherm® ci is a high-performance, exterior-wall cladding system that integrates a seamless air and moisture barrier with continuous insulation (ci) and advanced drainage capabilities. The result: excellent protection against moisture intrusion, as well as substantial energy savings thanks to a thermally efficient building envelope that enhances interior climate control and comfort. StoTherm® ci System works in any climate and in full compliance with today’s energy and building codes.  And because what covers the outside is just as important as the advanced elements inside, StoTherm® ci also provides a wide range of protective and decorative finish options to distinguish your project.

StoTherm® ci Accessories

Sto Mesh Corner Bead Standard

Sto Mesh Corner Bead Standard provides a solution to create true and straight corners which are resistant to chipping and cracking in StoTherm ci wall systems.

The Sto accessory is made of an angled strip of mesh (90° angle) reinforced with a plastic rail, providing a cost-effective and easy-to-apply alternative to the process of wrapping building corners with mesh reinforcement layers.

Sto Mesh Corner Bead Standard is compatible with all Sto basecoat products and provides strength and protection against everyday knocks, enhancing the long-term durability of the façade.

Sto Drip Edge Profile

Sto Drip Edge Profile is a PVC accessory with integral reinforcing mesh that creates a drip edge and plaster return in Sto’s two wall systems.  Its intent is to control the direction of dripping water and help protect the building enclosure from moisture intrusion in vulnerable areas such as fascia returns, balcony undersides and other projecting building elements.

Sto Drip Edge Profile is easy to apply, eliminating labor and costs associated with cutting of drip reveals in foam insulation.  The accessory also provides additional crack resistance with its integral mesh reinforcement and helps achieve straighter, cleaner lines at plaster returns.
