Atlanta, GA – Sto Corp., the innovative world leader in cladding, air barrier, coatings, and restoration systems has introduced StoTherm® ci XPS, a fully-tested, highly energy-efficient system which provides superior air and weather tightness and long-lasting thermal performance and durability.  The new system incorporates StoGuard® liquid-applied air and moisture barrier and Dow STYROFOAMTM Panel Core 20 Insulation.  

This sustainable, high-performance wall system helps lower energy costs and reduces the carbon footprint of buildings. In addition, StoTherm ci XPS offers unmatched aesthetic choices due to a wide range of decorative and protective finishes available in virtually unlimited colors.  

According to Sto Product Manager, Brian Chang, StoTherm® ci XPS meets both the ASHRAE design standard 90.1-2010, the new International Green Construction Code (IGCC) and the International Energy Conservation Code (IECC)* energy code requirements for continuous insulation.

The STYROFOAMTM Panel Core 20 insulation board from Dow has a closed cell structure which helps prevent liquid movement through the material and provides exceptional thermal performance with an R-value of 5.0 per 1”.  

The use of Sto TurboStickTM, a unique polyurethane spray foam adhesive, to attach the insulation board prevents thermal bridging from mechanical fasteners.  

Sto Therm ci XPS meets NFPA 285 fire testing acceptance criteria for wall assemblies, and the light-weight system creates less solid waste in production and at end-of-life than heavier claddings.  StoTherm ci XPS offers great design versatility with an extensive variety of decorative and protective 100% acrylic wall finishes which include options like brick, granite, limestone, stucco and metal, as well as the unique, patented self-cleaning StoLit® Lotusan® finish with Lotus-Effect® technology.
