Metro-Detroit, MI DC-315 Coatings Contractors
Colony Insulation in Clay Township, MI, offers expert application of DC 315 Intumescent Coating, a premier fire-retardant solution designed for spray foam insulation systems. DC 315 is a water-based, intumescent coating that provides a protective thermal barrier over spray polyurethane foam (SPF), ensuring compliance with modern fire safety codes while preserving the energy efficiency and structural benefits of foam insulation.
Unlike other coatings, DC 315 is specifically engineered to work with spray foam insulation, making it the leading choice among contractors, architects, and builders seeking code-compliant fire protection. It has been tested and approved to meet IBC and IRC code requirements as a 15-minute thermal barrier when applied over a variety of spray foam products.
What Makes DC 315 Different?
DC 315 goes beyond just a surface coating—when exposed to heat or flame, it expands (intumesces) to form a thick, protective char layer that helps delay heat transfer and provides crucial fire resistance to underlying spray foam. This critical layer helps contain and slow the spread of fire, buying valuable time for evacuation and emergency response.
Key Benefits of DC 315 Fire Retardant Coating:
- Code-Compliant Thermal Barrier: Meets building codes for use over SPF, including NFPA 286 compliant assemblies.
- Easy Application: DC 315 can be applied quickly using conventional airless sprayers, ensuring fast turnaround on construction sites.
- Low VOC & Water-Based: Safe for use in occupied spaces, eco-friendly, and minimizes odor during application.
- Flexible and Durable: Adheres tightly to spray foam while remaining flexible to prevent cracking over time.
- Cost-Effective Protection: Avoid costly retrofits or delays in inspection approvals by applying a certified and approved product the first time.
Where Is DC 315 Used?
DC 315 is used anywhere spray foam insulation is installed and needs to meet fire code requirements, including:
- Commercial and residential buildings
- Warehouses and storage facilities
- Agricultural structures and barns
- Industrial plants and mechanical rooms
- Basements, attics, crawl spaces, and other concealed spaces
