Air & Moisture Barrier

Protects the wall from moisture intrusion minimizing risk of water damage and associated repair costs.

Continuous Insulation

XPS or EPS Insulation options provide significant energy cost savings by eliminating thermal bridging.

Code Compliant

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

Systems, as low as L/240, 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.

Design Flexibility

Sto high performance finishes and coatings let you design most appearances such as EIFS, Stucco, Limestone, Brick and smooth- or water-repellant surfaces.

*if caused by water vapor diffusion and provided sufficient insulation thickness is used.

StoTherm® ci XPS

Durable, high performance, continuous insulation wall system.

A fully-tested system providing superior air and weather tightness, excellent long-lasting thermal performance and durability, incorporating StoGuard® liquid-applied air and moisture barrier and Owens Corning Foamular CI-C or Dow Styrofoam™ Panel Core 20 Insulation. This sustainable, high-performance wall system helps lower energy costs and reduces the carbon footprint of buildings.

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 StoTherm® ci 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.
