Continuous Insulation (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 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.

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.

Premium Finishes & Coatings: Sto high performance finishes and coatings provide superior weatherability and resistance to UV fading, mold and mildew

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.
