Spray Polyurethane Foam (SPF) A uniquely different approach to roofi ng. The system is lightweight, non-toxic and it’s durable and weather-resistant. Since roof tear-off is not always necessary, SPF reduces costs, noise and inconvenience during installation and allows for contours to create slope and drainage. SPF provides two layers of protection: 1. The fi rst layer of spray-applied polyurethane foam provides a seamless, monolithic waterproof barrier with continuous fl ashings. SPF adheres to most vertical or horizontal substrates. 2. The second layer is a protective coating: Cementitious, Silicone, Urethane, Acrylic or Polyurea The Benefi ts of SPF: - Time tested system developed in the late 1960s - Refl ective, seamless, lightweight roof system - Excellent insulating ability in hot or cold climates (high R-value) to reduce energy costs - Reduces installation costs due to the ease of application - Reduces maintenance costs - Can improve indoor air quality by reducing infi ltration of air pollutants - Eliminates ponding water and fl ashing leaks - Reduces building movement and thermal shock since insulation is on outside - Provides fi re resistance with a Class A fi re rating from UL, Inc. (Underwriters Laboratory, Inc.) on various substrates - Effective in cold climates (snow and ice), tropical climates (rain and high humidity), subtropical and desert climates (low humidity, intense solar radiation) - SPF is a renewable roof system with proper annual maintenance and consistent re-application of elastomeric coating during the life cycle of the roof system A Uniquely Different Approach to Roofi ng CentiMark’s Spray Polyurethane Foam (SPF) Roof System Layers CentiMark Systems topcoat with granules CentiMark Systems topcoat without granules CentiMark Systems basecoat Polyurethane Foam insulation (Thickness = R Value) 1” of Foam = R Value of 7 Substrate: wood, metal, concrete, other Choice of topcoat fi nishes depending on use: - Cementitious Coating - Silicone Coating - Urethane Coating - Acrylic Coating - Polyurea Coating Uses for SPF: - For Roofi ng - For Insulation - For Cold Storage (Freezers & Containers) CentiMark’s Omni Guard cementitious topcoat is an impact resistant material made up of white Portland cement and special resins that act as a walk pad over the entire roof surface and also provide a Class A fi re rating.
