Kemper System Buys STS Coatings


Seneca, NY-based waterproofing and roofing product manufacturer Kemper System America Inc. has acquired STS Coatings Inc., of Comfort, TX, and its four brands.

STS Coatings’ Wall Guardian Air Barrier, Roof Guardian Technologies, HeatBloc Ultra Radiant Barrier and GreatSeal Construction Sealants were a part of the deal, announced Tuesday (Dec. 13).

Terms of the transaction were not disclosed.

“Specifiers want to work with strong suppliers that can solve multiple [building envelope] challenges, including walls and foundations, and this greatly extends our range,” said Richard Doornik, president and managing director, Kemper System.

Four Brands Included

Kemper System provided the following descriptions of the brands included in the acquisition.

  • Wall Guardian Air Barrier: This spray- or brush-applied water-based liquid air barrier system offers three benefits in one—air barrier, water barrier, and vapor retarder. It is for use in cavity-wall constructions, including CMU/brick veneer, steel stud, insulated (continuous insulation), and insulated tilt-up construction.
  • Roof Guardian Technologies (RGT): These liquid-applied elastomeric roof coating systems help prolong the life of roofs, including metal, smooth-surfaced BUR, polymer-modified asphalt and single-ply roof systems. The RGT line includes 12 products including two Cool Roof rated systems, and two ENERGY STAR certified systems.
  • HeatBloc Ultra Radiant Barrier: This low-emissivity, water-based aluminum coating is engineered for attic spaces. Applied to interior underside of the roof deck, it can block over 80 percent of radiant heat to reduce cooling requirements, according to the company.
  • GreatSeal Construction Sealants: This line of caulks and sealants is widely used on doors and windows, masonry, roofing and siding. All products in the GreatSeal line are 100 percent solids, with no solvents and very low VOCs, and formulated for performance even in damp, dry or cold conditions down to 40 degrees Fahrenheit, the company notes.
