GacoSil S-20 Provides a Solvent-Free, Eco-Friendly Solution for Commercial Roofs

UL-rated and Miami-Dade County approved, GacoSil S-20 is the complete waterproofing system

SEATTLE – Gaco Western, manufacturer of the most technologically advanced elastomeric coatings and polyurethane spray foam for the construction and waterproofing industries, offers GacoSil S-20 – a solvent-free, eco-friendly silicone coating for commercial roofs –

“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.
