GacoSil S-20 Provides Top-Level Fire Protection with ASTM E108 A Rating Certification

Gaco Western, manufacturer of the most technologically advanced elastomeric coatings and polyurethane spray foam for the construction and waterproofing industries, will be showcasing its GacoSil S-20 – a solvent-free, eco-friendly silicone coating for commercial roofs – at the IRE show. To learn more about GacoSil S-20, visit the Gaco Western booth, #2252, at the International Roofing Expo, February 22 to 24, in New Orleans.

“Gaco Western is continuously working to improve the lifecycle of its products as well as implementing ways to reduce its environmental footprint,” said Chuck Skalski, vice president of Gaco’s Commercial Sales Division. “GacoSil S-20 is a great example of that. Not only is it an extremely high-performing commercial coating, it’s solvent-free and petroleum-free – S-20 offers an ecological advantage and meets the most stringent fire rating and building codes.”

GacoSil S-20 is a single-component, moisture-curing silicone rubber roof coating designed for use on sprayed-in-place polyurethane foam, metal, concrete, wood, built-up roofing and most single-ply roofs.

“The solvent-free silicone technology offers a new application option,” said Skalski. “With solvent-free silicone, the product fully adheres to the existing substrate, eliminating the need for tear-offs and lessening the impact on the environment and landfills. The use of GacoSil’s highly reflective coatings also provides increased UV resistance and energy savings.”

GacoSil S-20 has passed the ASTM E108 flame spread test and obtained the Underwriters Laboratories Class A fire rating – the highest level of fire protection available. Other ASTM testing provided ratings for tensile strength, tear resistance, hardness, water immersion, permeability, reflectance, emittance and flash point.

Additional product benefits:

  • Solvent and petroleum free
  • Can contribute up to 7 LEED points; rated by Cool Roof Rating Council (CRRC)
  • No ponding water issues
  • Less dirt pickup than conventional silicones
  • Durable, color stable, chalk and chemical resistant
  • Offers 1.5 gallon per square foot coverage to achieve a 10-year warranty; conventional silicone requires 2.5 gallons or more.
  • Up to 20-year product warranty

A uniquely versatile product, GacoSil S-20 can be applied to a variety of roof types:

Sprayed polyurethane foam      Cap Sheet
Metal                                         Torchdown
Concrete                                    Modified bitumen
Aged asphalt                              Built-up
Composite                                 Aged EPDM

Recent GacoSil S-20 projects include applications on commercial buildings including Sears, Target and JCPenney stores.
